Transitions™ lenses, also known as photochromic lenses, are a type of eyeglass lens that automatically adjusts to the level of light around you. In bright sunlight, the lenses darken to reduce glare and provide more protection from the sun’s harmful UV rays. In lower light conditions, the lenses become clear again, making them ideal for indoor or night-time use.

Another benefit of Transitions™ lenses is that they provide enhanced protection from the sun’s UV rays. UV radiation is known to cause damage to the eyes, including cataracts and age-related macular degeneration. Transitions™ lenses block 100% of UVB rays and up to 90% of UVA rays, providing a higher level of protection than regular clear lenses.

One of the biggest benefits of Transitions™ lenses is that they eliminate the need for multiple pairs of glasses. With traditional glasses, you would need a separate pair for indoor and outdoor use. Transitions™ lenses can be worn all day, regardless of the lighting conditions, which can be a great convenience and cost-saving.


Polarized Transitions™ lenses are designed to reduce glare from surfaces such as water, snow, and pavements. They can be especially beneficial for outdoor activities such as fishing, skiing, and cycling.

There are different types of Transitions™ lenses available, including generation 8 Transitions™ lenses, Xtractive Transitions™, polarized Transitions™ lenses, and the latest Style-Colour Transitions™ lenses. With each generation, the technology keeps getting better and the choices available now suit everyone. They also provide enhanced protection from the sun’s UV rays and can improve visual comfort.

Overall, Transitions™ lenses are a great option for anyone who wants the convenience of one pair of glasses that can be worn in any lighting condition, especially when you’re on the move or want to travel light. Transitions™ lenses should always be considered in addition to all your existing glasses to enhance your eyewear wardrobe.
