A Transitions® lens is a special type of lens that darkens in the sun and lightens when inside. This means you’ll get double the everyday wear out of the lens, as Transitions® glasses are prescription glasses that turn into sunglasses. Transitions® lenses are a hassle-free solution that makes switching between prescription glasses and sunglasses a thing of the past. Transitions®, a great brand of photochromic glasses and sunglasses, are designed to react to UV-exposure. This means that when you venture outside or are exposed to daylight, the lens automatically darkens based on the UV intensity. Similarly, when you move inside or into the shade, the lens tint brightens accordingly. There are many benefits to wearing Transitions® lenses as it means you always have the right pair of glasses at hand. Additionally, Transitions® lenses help reduce glare in bright lighting making them the perfect glasses and sunglasses combo. Furthermore, you’ll always enjoy optimal protection from the sun, as each pair of Transitions® lenses in sunglasses offers 100% UV-protection against harmful UV-rays. Plus, the 2-in-1 functionality of photochromic glasses can help you save money - as you don’t need to spend your money twice on prescription glasses and prescription sunglasses. The best part?
