Photochromic Lenses Explained

Transition Lenses Explained

Transition lenses, also known as Photochromic lenses, are a great option for those who don't want to have to switch between their sunglasses and daily use glasses throughout the day.

Traditionally, if you're wearing glasses with clear lenses, such as reading glasses, you would have to change to a different pair of prescription sunglasses when going outside to keep your eyes shaded from the sun.

Transition lenses are a convenient and versatile option for those who often find themselves transitioning from indoors to outdoors and don't want to carry a separate pair of prescription sunglasses.

Transition lenses also ensure your eyes receive optimal protection from UV rays no matter where you are or what you are doing. At Glasses2You We offer transition lenses with almost all of our frames, giving you thousands of options to choose from! 

How do transition lenses work?

These specially designed lenses are equipped with gas-filled technology that reacts dynamically to varying UV rays. When exposed to bright conditions, the lenses darken, providing optimal protection from the sun. As you transition indoors or encounter weaker UV intensity, the lenses promptly and seamlessly become fully transparent and clear once again.

Transition lenses from Glasses2You

We offer a light reacting lens to suit your budget and also offer the better known TRANSITIONS7® lenses (Transitions is a registered trademark of Transitions Optical, Inc., used under license by Transitions Optical Limited). 

Both of these lenses do the same job, although the TRANSITIONS® lenses tend to have a slightly longer life. These lenses are a very popular choice as you do not require separate sunglasses.
