Transition lenses are photochromic lenses. When these lenses come in contact with UV light (found in sunlight), the lenses transition into a dark tinted lens. The photochromic molecules of the lens are activated by UV light which changes their structure, ultimately causing the lens to darken.

 

What are the benefits of Transition lenses?
One versatile pair of glasses – rather than switching back and forth between your eyeglasses and sunglasses throughout the day, you have one convenient pair
Eye protection everywhere you go – Transition lenses offer protection from harmful blue light and block 100% of UV light
Reduced glare and eye fatigue – because Transition lenses darken based on the amount of light you’re being exposed to, these lenses minimize glare and help maintain the proper amount of light entering your eye
Perfect for varying light levels – Transition lenses respond to the amount of light in your environment, that means there’s an appropriate lens shade for every lighting
Great for kids – kids typically are exposed to approximately 3x the amount of sunlight than adults, making them more prone to the hazardous effects of UV exposure. Transitions help ensure full time eye protection and promote healthy ocular development
