Transitions Lenses: More Than a Sunny Day Convenience

Most people think of light-adapting lenses as a summer feature, a way to avoid carrying a second pair of sunglasses. But the technology behind Transitions® lenses is doing more than adjusting to sunlight. It protects the eyes from damage that can build up over time, in every season.
 

How Transitions lenses work 

Transitions lenses contain photochromic molecules embedded in the lens material. When exposed to UV light, those molecules change structure and darken the lens. Indoors or in low light, the molecules return to their clear state. The result is a single pair of glasses that adjust automatically as light conditions change, without a manual switch to sunglasses. 
 

Why UV protection matters year-round 

UV exposure is not limited to bright summer days. Water, snow and pavement all reflect UV light, which means overcast skies and winter glare can expose the eyes to UV rays too. Over time, unprotected UV exposure is linked to: 

• Cataracts: Clouding of the eye's lens that can affect vision over time. 

• Macular degeneration: Damage to the part of the retina responsible for sharp, central vision. 

• Photokeratitis: A temporary but painful sunburn of the eye's surface. 

• Pterygium: Growths on the eye's surface associated with long-term UV exposure. 

Because Transitions lenses respond to UV light rather than visible brightness, they provide a layer of protection even on cloudy days when someone might not otherwise think to wear sunglasses. 
 

Who can benefit 

Transitions lenses are not limited to any one age group or lifestyle. They can be a good fit for: 

• People who spend time outdoors for work or hobbies, including gardening, walking, golfing or attending outdoor events. 
• Anyone who wears prescription glasses and wants fewer pairs to keep track of. 
• Those looking to reduce long-term UV exposure as part of overall eye health. 
• People who are light sensitive or experience glare-related discomfort. 
   

Getting started 

Transitions lenses can typically be added to a new or existing eyeglass prescription in a variety of styles and tint colors. A Prevea optician can review your prescription, lifestyle and lens options to help determine whether Transitions lenses are a good fit for you.
