Although parts of the world are still extremely cold right now during these last months of winter, Spring 2016 is steadily approaching. The springtime brings about a lot of sunshine and new style. Every year introduces new fashion trends, and one major accessory is eyewear. Whether it’s sunglasses for the beach or your eyeglasses that you wear for work or school, be sure to stay up to date on the latest trends.
What exactly are polarized Sunglasses? We hear this term from time to time when discussing different types of lenses that can be used for sunglasses. Many golfers and fisherman use them for sporting activities, but now polarized sunglasses are becoming one of the most popular lenses, and people are starting to wear them for daily wear. However, many people who are unfamiliar to polarized lenses do not understand what the term polarized means.
What does it mean?
The word polarized stems from these lenses having a polarizing filter, which restricts vibrations of light either wholly or partially in one direction. Non-polarized sunglasses block a certain amount of light that passes through them, but do not eliminate glare. Both non-polarized and polarized sunglasses eliminate UV rays, but you will still feel the glare on your face when wearing non-polarized sunglasses. Wearing regular sunglasses may help your vision on a sunny day, but it will affect your vision tremendously on a rainy or overcast day, or even indoors. For most people, the absence of sun glare is the biggest difference they notice when wearing polarized sunglasses.
How do they work?
Polarized sunglasses on the other hand have a microscopic layer that block the polarized light that is reflected on to your eyes by glare. Polarized lenses strengthen your vision because there is an absence of glare coming through your lenses. The tints aren’t blocking out as much light in order to help your eyes see more clearly and feel more comfortable. Due to the tint not having to be so dark, the polarized lenses will help you see objects from afar a lot easier as well as see objects in your line of vision much quicker. This is important because it will allow you to react quicker while driving. Benefits like these are one of the many reasons why polarized lenses have become widely popular. Polarized sunglasses have become the most comfortable and beneficial glasses that are on the market.
How Can I Tell?
A great way to tell if a pair of glasses is polarized is to hold them up in front of a computer screen with your arms extended away from you in an upright position. Next, rotate the glasses at a 90-degree angle and look at the computer screen through the lenses. The screen will turn black if they are polarized. If the screen stays bright and lit when rotating, then the glasses are not polarized. The light from the computer screen is polarized; therefore, the polarized sunglasses will block out the polarized light resulting in the blackout.

What’s the difference between contact lens brands? There are many different brands of contact lenses out there, and we all have a different brand that is suited best for us. But what defines the best brand for most people? The most important step you should take before purchasing either brand is consulting with your doctor. Your prescription will have a major effect on which brand your doctor will choose because everyone’s eyes require different needs. We compared two of the most popular contact lens brands out there: Acuvue Oasys and Air Optix.
These contacts are designed with Acuvue’s Hydraclear Plus technology. This popular feature has wetness built right into the lens. Your eyes will feel moist all day and there will be no need for the constant application of eye drops.
Acuvue Oasys for Astigmatism are perfect for those with astigmatism thanks to Acuvue’s accelerated stabilization design technology. The American Optometric Association defines Astigmatism as a vision condition that causes blurred vision due either the irregular shape of the cornea, the clear front cover of the eye, or sometimes the curvature of the lens inside the eye. This defect makes it difficult for contacts to fit onto your eye properly due to the irregular shape of the eye. Acuvue has contacts specially made to help those who have astigmatism. These contacts will stay put with each blink, ensuring your vision stays clear all day long. Acuvue Oasys is a well-established brand that has been around for over a decade now and has a good reputation among its wearers and doctors. These lenses are slightly thinner with a center thickness of 0.07mm compared to Air Optix, which holds a center thickness of 0.08mm. Typically, a thinner lens is more comfortable and helps allow your eyes to breathe.
Air Optix is a newer brand, but by no means should be looked down upon. They hold a great reputation in the eye care field for being rather comfortable. The lenses are made with Hydraclear technology, which means that the lenses have a high volume of moisture. This may be especially convenient for those who suffer from problems with dry eyes. Air Optix Night & Day Aqua contact lenses offer optimum moisture for everyday wear. These lenses are so lubricating that they can even be worn overnight and have been approved by the FDA for up to 30 nights of continuous wear.
Moreover, both Acuve Oasys and Air Optix are both known for their ability to block of 90% of UV-A and UV-B radiations, which have destructive effects on your eyes. Therefore, you are safe to go out and have fun in the sun with either one of these brands.
