As digital screens become more common at home and school, your child’s vision health can become a focus of concern. From computers and tablets to smartphones and TVs, children are constantly exposed to blue light waves every day. In fact, digital learning is becoming the standard for many schools across the globe. While not all blue light is bad, too much of this kind of light can cause problems such as eye strain, headaches, sleep problems, and other daily disruptions. Knowing this, you may wonder if [blue light-blocking glasses](https://www.39dollarglasses.com/lens/blue495) may be a good option for your child. Even if your kid doesn’t currently wear prescription glasses, can they benefit from blue light-blocking glasses?

Over-exposure to harmful blue light rays isn’t just a problem kids are facing in the classroom. Whether it’s doing homework or surfing the web after school, young people spend a considerable amount of time at home in front of glowing screens too. When considering the effects artificial blue light has on children’s eyesight, it can be easy to point to computer screens, video games, and smartphones as the biggest offenders. However, blue light can come from other not-so-obvious sources as well. 

For example, did you know that about 30% of the Sun’s light is blue light? While this natural blue light can be beneficial for eye health, too much of it can cause problems.  So, what can you do to ease the negative effects this kind of light may have on your child?  Additionally, what happens if you don’t take measures to limit exposure to blue light? 

Although artificial blue light gets a bad reputation, certain types of natural blue light can be beneficial. Natural blue light rays from the sun help regulate our body's “natural clocks”, also known as the circadian rhythm. This natural rhythm is what prompts us to feel sleepy at night and wake up feeling energized during the day. 

While we don’t exactly rise and fall asleep with the sun anymore, humans once depended on the sun as their main light source for millennia. This is why blue lighting – especially those from natural sources – is actually beneficial during daylight hours. While natural blue light can be helpful, too much artificial blue light over time can cause problems. This is especially true for kids. 

Too much blue light can lead to issues such as eye strain, headaches, vision problems, sleeping problems, and consequently, increased difficulty while focusing on important tasks like learning. Since sleep is so important for growing minds, it’s important to try to limit the artificial blue light levels your kids are exposed to daily. However, eliminating screens isn’t exactly the most practical solution in today's digitally dominated world.  This is where [blue-blocking glasses](https://www.39dollarglasses.com/lens/blue495) for kids can help.

Blue light-blocking glasses may not solve all of the vision changes kids face as they get older, but they may help pave the way for a smoother transition as they begin incorporating more screens into their daily lives. As kids start to use digital screens for homework, schoolwork, and afterschool activities, they may report symptoms related to excessive artificial blue light exposure. 

Blue light-blocking glasses can help provide an added layer of protection for your child’s eye health. When worn as directed, blue light-blocking glasses for kids can help filter out harmful blue light, limiting exposure and reducing the strain on your child’s eyes.  

Blue light-blocking glasses can help your kid navigate through the digital world without experiencing symptoms from overexposure to blue light. When shopping for the best [blue blockers](https://www.39dollarglasses.com/lens/blue495) for kids, [39DollarGlasses](https://www.39dollarglasses.com/) has the perfect eyewear option for your youngster’s busy lifestyles.

Do Kids Need Blue Light Glasses?

The eye is one of the most complex systems of the body. Even for those who know a lot about the eye, it’s still a wonder how we’re able to see! So for the everyday person, it’s understandable if you have trouble deciphering your prescription. To help you get to know your eyes and eyesight a little better, here’s a basic guide to the two most common eye conditions, nearsightedness and farsightedness.     

### What is nearsightedness?

Nearsightedness, or myopia, is when you can see things close to you, but things get blurry at a distance. 40% of Americans are nearsighted, making this a very common issue. If your prescription contains a negative number (-), this indicates you have myopia. A larger prescription number means more correction is needed. 

### What is farsightedness?

Farsightedness, or hyperopia, is the opposite of nearsightedness. If you have hyperopia, you are able to see things that are far away, but things up close are blurry. This is a rarer condition, affecting only 5-10% of Americans. If your prescription contains a positive number (+), this indicates you have hyperopia. A larger prescription number means more correction is needed here as well. 

However, needing reading glasses may not mean you are farsighted. You may have presbyopia, which is common in old age. It is when the lens of the eye becomes thicker and hardened and seeing things up close becomes blurry.  

### What causes nearsightedness and farsightedness? 

Now that we know the difference, what causes these conditions? First, it helps to understand how we see. In simple terms, light enters your eye, filters through the cornea and lens which helps to focus it directly onto your retina. Your retina sends the light through the optic nerve and to your brain to process it into the image you see. Nearsightedness and farsightedness happen when light isn’t able to precisely reach your retina due to the shape of the eye and/or cornea. That’s why these two conditions are referred to as refractive errors.

In the case of nearsightedness, the light is focused in front of the retina, not quite reaching it because of an eyeball that is shaped too long or a cornea that is too curved for light to hit the retina correctly.

Farsightedness is when the light is focused behind the retina, aiming past it because the shape of the eyeball is too short or the cornea is too flat for light to hit the retina correctly. 

No matter what condition you have, corrective lenses can help you see better.

If you haven’t seen your eye doctor already, it’s important to get an expert diagnosis so that you can get the right corrective lenses to help you see clearly. Then, you’ll be free to explore the many styles of glasses and brands of contact lenses that best suit you!

Nearsighted vs. Farsighted: What’s the Difference?

Men’s glasses trends change over time, but choosing frames that look good isn’t complicated. With a few simple tricks, you can pick the best glasses for your style and easily stay on-trend. Here’s your guide to wearing the latest glasses trends.

Above all, glasses should complement your face shape. You could wear the latest frames, but you’ll feel the best if they actually match your look. 

Generally speaking, faces can fall into a few broad categories. At one end, there are squares and rectangles. These are faces with sharper features like angular jaws and wide foreheads. At the other end are rounder faces. Think softly slopped chins and rounded hairlines.

In the middle are “diamond” and “heart” faces, which have a mix of soft and square features.

In most cases, glasses that add contrast look good. If you have a soft face shape, choose bolder frames with sharp edges. They’ll enhance your jaw and balance your features. On the other hand, sharper face shapes are accented well by softer frames.

Remember that this is just a general rule of thumb. You should always go with styles that make you feel good.

Next, think about your daily attire. Glasses that match your everyday style are easy to wear and keep you effortlessly on-trend.

You’ve got three things to think about:

### Color

Frames should match your daily style. You don’t need a new pair for every outfit, just think about the shades you typically wear. Like earth tones? Go for neutrals such as white and gray. What about brighter colors? Double down with bold primaries like red and blue. (You can always skip this step and stick with simple black frames that match everything.)

### Material

Glasses can be made of anything from metal to plastic to wood and more. If you like classic styles, metal wire-frame glasses are an easy pick. For something more modern, choose clear plastic frames.

### Pattern

Plain frames look great, but you can add a pattern for a more eye-catching look. Tortoiseshell is probably the most iconic glasses frame pattern, but you can also try anything from stripes to subtle color gradients. These styles are perfect if your daily attire plays with patterns and colors.

Glasses should match your lifestyle, so consider what activities you do throughout the day. 

If you’re on the move, focus on comfort with lightweight glasses. Or keep it sharp at work with a classy pair of sleek metal frames.

Beyond style, certain lenses are better for certain activities.

For work and school, stylish glasses with an oil-resistant coating will stay clean all day. For outdoor jobs, consider adding Transitions® lenses to keep sunlight at bay.

Now it’s time to talk about the latest trends. These styles are the perfect mix of on-trend and timeless — you really can’t go wrong here.

### [Clear](https://www.39dollarglasses.com/eyeglasses/clear_white-men)

Clear frames are modern and classy, but they can swing playful too. Try wearing colorful clear frames for a brighter look.

### [Oversized](https://www.39dollarglasses.com/eyeglasses/extra_wide)

Big glasses are hot right now. Be sure to choose an oversized frame shape that complements your face for the best look.

### [Half-Rimmed](https://www.39dollarglasses.com/eyeglasses/men-semi_rimless)

Half-rimmed glasses emphasize sharp features. They’re ideal if you need glasses that look good at work and on the weekends.

### [Tortoiseshell](https://www.39dollarglasses.com/eyeglasses/men-tortoise)

Tortoiseshell is a stylish look that works on everyone. Go for the classic, or spice things up with a colorful twist.

### [Round](https://www.39dollarglasses.com/eyeglasses/men-round)

Round frames add attractive contrast to square faces. Mix and match the style with other designs, like round clear frames or round tortoiseshell.

### [Aviator](https://www.39dollarglasses.com/eyeglasses/aviator-men)

Pick this timeless trend if you want something simple but striking. The classic design always looks fresh, whether you’re getting stuff done outside or at work on a computer.

[39DollarGlasses](https://www.39dollarglasses.com/) has the latest trends to keep you looking good. As a company founded by eye doctors, we offer the highest-quality glasses at the best price, from clear frames to aviators. We custom-make each pair in our New York lab and ship them straight to your door. Order your new glasses and stay in style with [39DollarGlasses](https://www.39dollarglasses.com/)!

What Glasses Are In Style For Men?

When they look for the best lenses, many ask, "Which is better, [Varilux ](https://www.39dollarglasses.com/lens/varilux)or [Crizal](https://www.39dollarglasses.com/lens/prevencia)?”  To answer the question, it’s important to understand the difference between these two products. In a nutshell, Varilux is a lens type, and Crizal is a brand of  lens treatment. Varilux, a brand of corrective lens by Essilor International, provides progressive correction for near, intermediate, and far vision.

### What are Varilux Lenses?

Glasses with [Varilux](https://www.39dollarglasses.com/lens/varilux) progressive lenses are especially beneficial to older adults who have worn glasses because of nearsightedness or astigmatism and then developed presbyopia or farsightedness.

People in their 40s and 50s, who’ve never had trouble seeing things close to them, can start having trouble reading smaller print. In other words, they become farsighted and, at some point, need glasses for close work and reading. If they already wear glasses to help with distance or astigmatism, their options are switching between two pairs of glasses, getting bifocals, or choosing progressive lenses. Switching glasses is annoying and inconvenient. People lose their reading glasses and must hunt for them or opt for wearing them on a chain around their neck. Many people often choose to get bifocals instead. Bifocals divide the lens into two separate areas for near and far vision and may or may not have an etched line to divide the two. The trouble with bifocals is that switching back and forth between the two lenses can be disorienting, even dizzying. Each time you change, your eyes need to adjust. Going up and down stairs becomes difficult for some, as does taking notes on a page while watching a screen or speaker on a stage. 
Progressive lenses like Varilux solve these problems because rather than having just two different lenses, they blend the two, creating an easy transition and a more natural sight experience. Each lens is modeled using a computer to design a seamless transition from seeing things close up and those far in the distance. A wearer's eyes will transition from far to near and everywhere between, effortlessly and smoothly.

Released in 1959 as the first progressive lens marketed,  Variluz has continued to lead the field in innovation and advancement.   Varilux S Series lenses are the most advanced progressives available today. While they provide all of the usual benefits of  Varilux lens designs, they also eliminate distortion and provide better edge-to-edge clarity. The patented lens shape and cutting-edge technology from the Varilux S Series lenses actually help people see the way they did before they needed progressive lenses.

### What is Crizal? 

[Crizal](https://www.39dollarglasses.com/lens/prevencia), also by Essilor International, is not a type of lens but a coating or finish added to any lenses. A Crizal coating will reduce uncomfortable glare from digital devices, sunlight, and bright lights at night. Sunlight through a window can make working on a document or reading more difficult because of the glare. Adjusting between bright digital light from electronic devices and a book or the road ahead can also cause problems. 
While helping with sun and digital glare is valuable, for many, a Crizal anti-glare coating is most helpful when driving at night. Crizal provides safer, more comfortable nighttime driving.  Night vision can be problematic for people with astigmatisms and can deteriorate for all of us as we age.  Sometimes eyes don’t adjust between bright light and darkness as quickly as they need to.  Streetlights, taillights, and especially oncoming headlights can make seeing well in the dark after the glare more difficult. A Crizal coating cuts the glare, allowing quicker adjustment back and forth between bright and dark conditions. If roads are wet and the light reflects off the water and into a driver's eyes, the glare can be even more dangerous, and Crizal helps with that.

The Crizal thin coat finish does more than prevent glare and improve night vision. It also helps reduce damage to lenses from smudges, dust, water, and scratches.  People, especially children and athletes, who are particularly rough on their glasses benefit tremendously from the special finish. By preventing damage, wearers see better longer and need to replace their glasses less often.

### Which is Better, Varilux vs. Crizal?

While people don't necessarily need to choose between Varilux and Crizal because they can certainly have both, each product offers certain populations more benefits.
Varilux lenses help anyone who needs correction for both myopia or nearsightedness and presbyopia or farsightedness. People with astigmatisms, which are distortions of the eye and farsightedness, can also get progressive lenses like Varilux. Many people have all three conditions by the time they are in their 40s or 50s, and progressive lenses make their lives easier.  If someone has tried bifocals and struggles with disorientation and dizziness or needs clear middle-distance vision, Varilux progressive lenses are ideal.
Crizal-coated lenses are appropriate for all three vision correction needs but are especially good for those with poor night vision.  Although older people struggle with night vision, even young people with astigmatism have trouble adjusting between bright light and darkness at night. Stigmatism affects the shape of the cornea. Instead of the normal sphere shape, the cornea becomes more egg or football-shaped. The distortion changes how the eye interprets light and can cause headaches and eye strain without treatment. A Crizal coating allows eyes with astigmatism to properly focus on the visible light coming in, allowing for better night vision and adjustment between electronic screen and bookwork.

When it comes to Varilux vs. Crizal lenses, one helps wearers who need glasses to see both near and far, and the other helps people cope with glare, especially at night.  Keep in mind that you can order eyeglasses with Varilux lenses and Crizal coating to get all the benefits they each offer.

### What is Astigmatism?

Astigmatism is a common eye condition. About one in three people have it, and it generally causes blurry vision according to the National Eye Institute. Astigmatism is easily treatable with corrective lenses. It affects the cornea. You can think of the cornea as a clear dome on the surface of your eye. The dome needs to be shaped evenly to have clear eyesight. With astigmatism, the dome is slightly misshapen, almost like an oval instead of a circle. This is called corneal astigmatism.

Light travels through the cornea before reaching the rest of your eye. A properly shaped cornea will focus light rays to a single point, giving you well-focused eyesight. With a misshapen cornea, the light refracts and causes distorted vision. The refractive error can also cause eye strain. 

Lenticular astigmatism is a similar but less common condition that affects the eye’s lens rather than the cornea. Glasses can treat both types.

### Is there an Astigmatism Test?

Astigmatism is diagnosed during a standard eye exam. Your doctor might use a visual acuity test to check your vision, which includes reading letters on a chart across the room. If you have astigmatism, the letters will likely be blurry.

Your eye doctor will also determine if you have with-the-rule astigmatism or against-the-rule astigmatism. With-the-rule astigmatism means the cornea is misshapen horizontally while against is misshapen vertically. Your doctor will use this info to provide an effective glasses prescription.

Blurred vision is one of the most common astigmatism symptoms, but you may also notice headaches because of refractive errors. Cases of severe astigmatism may have more intense symptoms than slight astigmatism — you should talk to an optometrist if you’re experiencing painful symptoms.

### What is a Good Treatment for Astigmatism?

Prescription glasses are the best treatment for astigmatism. After an exam, your doctor can prescribe lenses that give you clear vision. Prescription astigmatism glasses will adjust how light enters your cornea, ensuring it’s accurately focused so your eyesight isn’t distorted. 

Wearing [contact lenses](https://www.39dollarglasses.com/contact-lenses) can also treat astigmatism. Some soft lenses (known as toric lenses) have a donut-like shape that fixes vision distortion. Glasses or contacts are both great ways to correct astigmatism.

What is Astigmatism?

You finally visited your eye doctor and got a new glasses prescription. There are words, maybe a minus sign, or a plus sign and some letters and numbers - but what does it all mean? Learning how to read your eye glasses prescription can seem difficult at first, but is something that every person who wears prescription eyewear should learn how to master. During a comprehensive eye exam, the lens power of each eyeglass prescription or contact prescription is perfectly tailored to meet the specific glasses lenses or contact lens required. It's critical to understand any eye prescription so that you can purchase the correct pair of glasses and maintain optimal eye health - but don't worry! With our ultimate guide to understanding eyeglass prescriptions, you'll soon be ready to find the perfect pair of prescription glasses in no time.

### Why are Eye Glass Prescriptions Important?

Knowing the level of lens power needed is necessary to order glasses or contact lenses online, or anywhere! Ordering eyeglasses with the wrong eye prescriptions can result in double vision, distance vision issues, and may even worsen near vision or cause other vision problems. Even when worn daily, an incorrect prescription won't correct farsightedness or provide the astigmatism correction needed to maintain daily eye health. Your eye care professional will make sure each eye exam correctly identifies what eyeglass prescription is needed. In most cases, the left eye will need a different lens than the right eye, and the pupillary distance will also be measured to assure the correct fit overall. Some people may even require a very specific nearsighted prescription, lenses to correct astigmatism, prism correction, or added magnifying power. If you don't know how to read your vision prescription to purchase the correct pair of glasses or contact lenses, your vision won't improve! Those who want to wear both eyeglass lenses as well as contact lenses typically need a separate eye exam and special contact lens fitting to assure the correct contact lens prescription is determined as well. Without a general understanding of the lens power needed for both eyeglass prescription and contact lenses, it's easy to accidentally order eyewear that won't work for your unique vision needs. This is why is it so important to understand how to read eye glasses prescription and contact lens prescription properly.

### How to Properly Read Eye Glass Prescriptions

Using an Eye Glass Prescription to Order RX Eye Glasses Online
Now you're ready to use your eyeglass prescription to order eyeglasses online with the correct lens power. Once you find the perfect pair of glasses or sunglasses on [39dollarglasses.com](https://www.39dollarglasses.com/), click "select lens type" to choose the type of lenses you need. You can select from distance vision glasses, reading glasses, regular bifocals, or progressives. Next, you will enter your prescription using the example eye prescription chart and eye prescription abbreviations as explained above. Be very careful to double check the eye prescription provided by your eye doctor to make sure you are entering the left eye and right eye information in the correct spaces. Don't accidentally use a minus sign if a plus sign is needed, because that will drastically change the eye prescription! After adding all the information for both eyes and entering your pupillary distance, you are ready to move on to select any lens type or coating required. And that's it! You have used your eye prescription from an eye doctor to order eyeglasses online. 

[39dollarglasses.com](https://www.39dollarglasses.com/) has a wide range of eyeglass frames and sunglasses for many eye conditions, and eye prescriptions.

How Do I Read My Eye Glasses Prescription?

Many people worry about contacts getting lost in their eyes — but don’t worry, that’s not possible. 

However, lenses can shift out of place and become temporarily stuck, and that can cause problems if not addressed.

Here’s the good news: with a few simple precautions, you can comfortably wear contacts and avoid stuck lenses. Here’s everything you should know about safely using contacts.

__How do Contacts Get Stuck?__

A stuck contact lens is uncomfortable, but it’s not typically a major problem. (You should contact an eye doctor if a lens is stuck in your eye and you can’t remove it safely.) 

Contacts get stuck for many reasons, including rubbing the eyes while wearing lenses. In this case, the lens can fold over itself and end up stuck beneath your lower or upper eyelid. You can generally fix this by closing your eye and gently massaging it, pushing the lens out from under the lid.

Sleeping while wearing contacts is another big culprit. This is usually a problem among gas permeable contact lens wearers (GP lenses). Unlike a soft contact lens, GP lenses are firm and reusable. However, they have to be removed and cleaned at night. Leaving them in while you sleep leads to bacteria build-up and dryness, which could result in a stuck lens.

The same problem applies to soft lenses. Your eyes are exposed to particles in the air throughout the day. Eyes are good at cleaning out these particles, but adding contacts to the mix can cause trouble. Without removing your contacts at night, the lenses can grow bacteria and get stuck to your eyes.

Finally, contact lenses can get stuck if you deal with dry eyes. Contacts are designed with moisture in mind. If they get too dry as a result of dry eyes, the lens can become hard to remove.

__How Can I Reduce the Risk of Getting Contacts Stuck in Eye?__

So how do you avoid contacts getting stuck? The first rule is simple: don’t sleep while wearing contacts. Wearing contacts overnight increases the risk of stuck lenses and even infections. It’s not worth it.

Next, reduce the risk of stuck lenses by being mindful of how you touch your eyes. It’s completely normal to rub your closed eyes occasionally, but that can cause problems while wearing contacts. Be careful around your contacts, just like you’d be careful around a pair of glasses. Avoid excessively touching your eyes throughout the day, and be gentle when you do touch them. (Many people rub their eyes if they feel sore or irritated. You should talk to a medical professional if you regularly experience discomfort while wearing contacts.)

Lastly, you can avoid stuck lenses by addressing dry eyes. Talk to your doctor about eye dryness to get the best treatment. Your health care provider may recommend using eye drops to moisturize your eyes, which can reduce the risk of stuck lenses.

Can a Contact Get Lost in Your Eye?

Light sensitivity is a big problem if you experience migraines. Bright lights can trigger new pain and worsen existing symptoms. Either way, managing the kind of light hitting your eyes is an important step in finding relief. 

Our [Neurolux™](https://www.39dollarglasses.com/lens/neurolux-soothing) migraine glasses, can help prevent migraines and stop triggers before they cause pain by blocking harmful wavelengths. Here’s everything you need to know about glasses for migraines.

To understand why tinted glasses for migraines are so effective, we need to talk about what’s happening when light causes pain. The human eye has cells that detect light. These cells interact with other vision systems, including a sensitive nerve. For people with migraines, light “hits” that nerve and triggers painful symptoms. This can result in new migraines and makes it harder to alleviate pain. Doctors call this problem photophobia.

Scientists have identified the specific wavelengths responsible for pain. Light measuring between 480 and 520 nanometers can be particularly irritating. [Neurolux™](https://www.39dollarglasses.com/lens/neurolux-soothing) soothing lenses neutralize those painful wavelengths before they hit your eyes, especially while using screens. Think of it like a shield protecting you from migraine pain. The lenses use FL-41 glasses technology to filter out harmful light waves and help you live pain-free.

Your phone and computer screens produce harmful blue light. Too much blue light exposure can cause dry eyes, fatigue, and general eye strain. You might notice these symptoms after working at a computer for long periods or after watching a movie. Neurolux™ soothing lenses can help you avoid these symptoms. 

Computer screens can trigger migraines, but so can other light sources.  Our lenses protect you from all common light triggers. Fluorescent lighting is a common migraine trigger. You might notice its effects while shopping since a lot of stores use fluorescent lights. They may look steady, but they actually invisibly flicker faster than your eyes can process. For people with migraines, fluorescent flickering can quickly cause painful symptoms.
Neurolux glasses filter fluorescent lighting and other triggering wavelengths to prevent pain. 

You deserve migraine relief. Choosing [Neurolux™](https://www.39dollarglasses.com/lens/neurolux-soothing) glasses gives you a medically proven defense against pain by stopping light triggers before they strike. Migraine glasses aren’t a cure, but they are an excellent defense against symptoms. Neurolux light sensitivity glasses empower you to manage pain during headaches and reduce the risk of daily migraine attacks. 

At [39DollarGlasses](https://www.39dollarglasses.com/), we believe in making high-quality and affordable migraine glasses. That’s why our custom Neurolux™ lenses can be added to any frames — all starting at $89. We make migraine prevention easy with a wide selection of frame styles for everyone. You can even add [Neurolux™](https://www.39dollarglasses.com/lens/neurolux-soothing) technology to prescription lenses.

Ordering online is fast and simple. We custom-make every pair of migraine glasses in our New York lab, then ship them straight to your door. Don’t wait for another migraine to ruin your plans, get relief with Neurolux™! 


What are Neurolux™ Soothing Lenses and Do They Work?

The eyes are arguably one of the most complex systems of our bodies, so it’s only fitting that taking care of them is serious business. Did you know there are multiple professionals that specialize in just the eyes? With how similar their names all sound, you might have mistaken one for the other as you were on the hunt for a new eye doctor. Or, was just puzzled altogether as to who you should see. Read along for a quick guide to help break down each expert. 

### What is an optometrist?
The person who you regularly see for an eye exam? That is typically an optometrist. They are a doctor that specializes in eye care, who can examine, diagnose, write prescriptions for and perform minor procedures on your eyes such as laser eye surgery. Simply put, they help manage the day-to-day maintenance and care of your vision. 

After they complete an undergraduate education, optometrists are required to fulfill four years of optometry school in order to receive their doctor of optometry degree. 

### What is an ophthalmologist?
More serious eye needs call for an ophthalmologist. They are medical eye doctors who can perform both major and minor surgery, as well as all the responsibilities of an optometrist, such as routine eye exams.  

Unlike optometrists, an aspiring ophthalmologist must complete medical school plus residency to begin practicing. Some will specialize in a certain part of the eye or an eye disease, like glaucoma, or pediatric eye care, which requires additional training.  

### What is an optician?
Opticians help fill the prescriptions of glasses, contacts and other eyewear made by optometrists and ophthalmologists. They cannot perform eye exams, diagnose eye diseases or write those prescriptions themselves, however, they are experts in fitting, measuring and adjusting glasses to each individual, in addition to making recommendations on what vision products or devices could best work for you. 

Each state has different qualifications to become an optician. Generally, one must complete an apprenticeship or an associate’s program and obtain a state license and/or a certificate. 

### Which eye professional do I need?
The first line of defense to any eye problems you may have is to go to your primary eye doctor, or an optometrist. They can help diagnose the issue and either provide treatment, or recommend you to an ophthalmologist who can better help you. 

For all your prescription glasses, sunglasses and contacts needs, an optician will have all the answers to have you seeing, feeling and looking your best.

How To Style These New Fall Glasses Arrivals

Out of all five senses, vision is arguably at the top of the list as one of the most important. Think of how sight is used from the moment you wake up to the moment you fall asleep. The world would be a lot less dynamic without being able to see. 

That’s why you should never slack on routine eye exams, especially if you already wear corrective lenses. Even if you have perfect vision, there are other important reasons to see your ophthalmologist or optometrist regularly. 

### 1. To Keep Up With a Changing Prescription
If you already wear glasses or contacts, it’s important to regularly get an exam to be on top of any changes in your vision so your eyesight stays sharp. 

### 2. If You Wear Contact Lenses
For contact lens wearers, your prescription most likely expires in one year. If you need to re-up on lenses, it’s imperative to get a contact lens exam so that you’re able to order more. Fit is also super important, so if there are any changes with how your contacts feel, your doctor can help recommend another brand to suit your needs. Contact lens technology is also constantly changing so they might even be able to recommend a new brand to try. 

### 3. To Detect Eye Diseases
Alongside a variety of tests, your eye doctor will usually put eye drops in your eyes to dilate your pupils so that they can get a clearer look inside. With such a close examination of your eye’s inner workings, they can check your eyes for diseases like cataracts, glaucoma and macular deterioration. This is even more important as you get older since these are usually age-related, even if you’ve never had eye issues earlier in life. 

### 4. To Catch Other Health Problems
Your eyes can actually give a great picture into your overall health. With a close look at all the blood vessels, nerves and other parts of the eye, your eye doctor can detect diseases that affect you in other parts of your body like high blood pressure, high cholesterol and even cancer– sometimes before symptoms are noticed by you. With early detection also comes early treatment which will be vital in hopefully preventing further complications. 

### 5. If You Have Diabetes
Those with diabetes are more vulnerable to certain eye diseases, specifically diabetic retinopathy, caused by high blood sugar’s effect on blood vessels. This can lead to vision loss so the American Diabetes Association recommends those with diabetes to get an eye exam yearly.


5 Reasons To Get Routine Eye Exams Even If You Have Perfect Vision

Well-loved glasses will inevitably get a little dirty. Wearing them day in and day out will gather dirt, grime, grease and smudges on your frames that will make it harder for you to see clearly. That’s why it’s important to regularly clean your glasses.

Whether you clean them as needed, or the recommended once a day, all that matters is that you do it often to keep your frames in pristine condition. 

Cleaning your glasses may seem like a simple enough task but there are a few rules to follow. Read on for the do’s and don’ts when it comes to keeping your lenses and frames in tip top shape. 

DO wash your hands before cleaning. This ensures you aren’t dirtying your glasses again after you clean them. 

DON’T use harsh chemicals. There’s no need to use any chemicals to clean your glasses as they may rub off any special coatings you have on your lenses. 

DO use soapy water. Just a little bit of dish soap and water is all that’s needed! 

DON’T use napkins, tissues, a t-shirt or towel to wipe your lenses. These materials can cause microabrasions on your lenses that can permanently damage them and cloud up your vision. 

DO use a microfiber cleaning cloth. This ensures you won’t scratch your lenses and easily wipes away dust and fingerprints.

DON’T forget to clean your microfiber cloth. A dirty microfiber cloth with buildup just won’t clean as well.

DO clean the entire frame. While cleaning your lenses, give the entire frame a wipe as well to get rid of any dirt, dust or oil, especially on the nose pads. 

DON’T forget to clean your sunglasses too! Give your sunglasses the same care as your prescription frames by gently cleaning them the same way.
