Light Reactive Lenses

Lenses that darken on exposure to sunlight as well as blocking UV seemed magical in the 1960’s when they were first introduced – since then the colour changing technology has evolved, reacting at a much faster speed and they are now one of the most popular material choices for spectacle lenses

So why were they made? Many people dread going outside because of the glare and discomfort caused by the sun, resulting in headaches, eye fatigue and visual discomfort. The solution; lenses that adapt to changing light conditions. Outside in bright sunlight they go as dark as sunglasses and inside they are completely clear. Plus, they always block 100% UVA/UVB rays giving you safe, healthy vision, reduced glare and eye fatigue. So from dawn to dusk, where ever you are, your world looks more vivid, vibrant and you never miss a moment.
