A photochromic lens is made with small molecules of silver halide and chloride built into the body of the lens, which undergoes a chemical process on exposure to UV radiation or sunlight. The aforementioned chemical process leads the in-built molecules to change in size and orientation, thus darkening the appearance of the photochromic lens and giving it the sunglass tint. Since this chemical process is reversible, the lenses return to clear once the wearer returns to a place with limited UV radiation or no sunlight.
Benefits of Photochromic Lens

Purchasing specially designed eyeglasses that are equipped with a photochromic lens can be a great investment for those with specific needs within one pair of eyewear.
Let us take a look at some of the benefits of a photochromic lens within eyewear:

• Cost-Effective:

Since a photochromic lens can be installed within a pair of simple prescription lenses, the need for a second pair of tinted sunglasses for the outdoors is eliminated. The two-in-one solution helps the wearer get the benefits of both glasses in an adaptive pair while cutting down on any high costs the wearer might have in terms of buying a second set of eyewear.

• Protection from Radiation:

The central objective of a photochromic lens is to protect the wearer from significant exposure to UV radiation when outdoors. Since prolonged exposure to unfiltered sunlight can lead to eye problems and even blindness, investing in a protective pair is crucial.

• Convenience:

As aforementioned, the double-solution provided by a pair of glasses equipped with a photochromic lens is great for wearer’s convenience as their everyday-wear prescription glasses can turn into tinted sunglasses the moment they step outside.

• Long-term Eye Health:

Protection from UV Radiation is imperative for eye health in the long run. To keep problems like cataracts, blurred vision, and headaches at bay, investing in a pair of photochromic lenses is essential.

The nature of a photochromic lens within eyewear is to fulfil different functions within one useful pair. Explore our website, and we can help you find the perfect pair of photochromic eyeglasses for your convenience, so you can look stylish and stay protected at the same time.
