Does anyone wear glasses with those “transition lenses”? You know, the ones that darken to become sunglasses when you step into the light? Are we wrong in assuming that they’re kind of uncool? (Read: for old people.)
What if you could get the benefits of automatic sunglasses without the actual frames? Researchers in Singapore have now created contact lenses with the same capability; they remain clear until exposed to the UV light of the sun, and darken to shade your vision (and also protect the eye).
