You may have seen some prescription lenses that darken outdoors when they are exposed to sunlight. These aren't just a magic trick made to enhance normal glasses! These glasses use photochromic lenses which are also known as "transitions light intelligent lenses" or "transition lenses" for short. Activated by bright light, these adaptive lenses can be a great option for people who want to easily protect their eyes from harmful UV rays. Now that you know the correct term for this special type of transitions optical prescription sunglasses, read on to learn more about photochromic lenses and how helpful they can be.

How do Transition Lenses Work?

Transition lenses use a specially designed photochromic technology that are activated by UV rays. Photochromic lenses darken automatically when they are exposed to sunlight or any other light conditions that require an increase in UV light. Photochromic lenses are offered in a variety of lens materials including glass photochromic lenses, plastic, and polycarbonate. Transition lenses provide full light protection from both UV and UVB rays and many of them also have anti reflective coatings as well. Since these light adaptive lenses are sensitive, they will react differently depending on the level of visible light, whether that is bright sunlight, harsh lighting, or fluorescent lights. Standard photochromic lenses will be completely dark, like regular polarized sunglasses, when exposed to bright sun, but may only have a slight tint indoors or in other moments of everyday life with less UV exposure. This will assure that your eyes are protected from any level of UVA and UVB no matter how little. It's important to note that transitions light intelligent lenses will also protect from harmful blue light that is emitted from digital devices. Regular exposure to blue light can lead to digital eye strain and, over time, can be damaging like UV rays.

Should I get Transition Lenses?

There are many reasons why photochromic lenses may be the best option to provide the best vision care and protection for you. Here are some of the biggest benefits for choosing transitions lenses:

1) Photochromic lenses provide optimal light protection.

Glasses that utilize photochromic technology like transitions optical lenses are one of the best ways to protect your vision from ultraviolet light, UV radiation, reflective glare, blue light, or any other harmful rays on the light spectrum. They can also be extremely helpful for those who are light sensitive indoors or who may need assistance from a light adaptive lens to maintain sharper vision. Because photochromic lenses work automatically, they may provide more protection than typical non-transitions lenses when dealing with visible light changes. While photochromic lenses cost more than other eyeglass lenses, they are ultimately more cost effective in the long run since they eliminate the need to buy an additional pair of prescription sunglasses for protection from UV rays.

2) Photochromic lenses work automatically, all the time.

Photochromic lenses also protect your eyes better than regular lens materials from UV exposure, UVB rays, and the harmful blue light emitted from digital devices because they can be activated at any time. Many people may put on a pair of regular sunglasses when they are in bright light conditions, like direct sunlight, but may not realize that UVA and UVB rays can affect the eyes at lower levels as well or even during cold weather. This is why photochromic lenses or "transitions lenses" are better, because they automatically adjust to provide optimal protection depending on the UV light or any light conditions that are present.

3) Photochromic lenses are easy to start using and are more convenient.

Transitions lenses can also be added to almost any pair of prescription glasses including progressive lenses, single-vision, bifocals, and trifocals. Which means that anyone can still maintain their regular prescription glasses while also benefiting from the ease of adding variable tint lenses, like photochromic lenses. Finally, photochromic lenses (like transitions optical limited lenses) are more convenient. When going on vacation or heading to work in the morning you don't have to worry about bringing along a pair of sunglasses or blue light adaptive lenses. Simply wake up, put on your transitions lenses, and go - knowing that your eyes will be protected all day!

If you have further questions about transitions optical lenses, talk to an eyecare professional to see if photochromic lenses are right for you. Depending on your lifestyle, occupation and UV light exposure, you may even benefit from advanced photochromic performance eyewear like xtractive lenses from transitions optical limited which provide a darker lens experience.
