Hooray?: Auto-Tinting Contacts Coming Soon

You know those eyeglasses that automatically darken whenever you go outside? I know, they remind me of pederasts too for some reason (but they look great on you, really). Now scientists are working on transferring the technology to contact lenses.

Traditionally, these light-to-dark lenses have been constructed by coating a normal lens with a photochromic dye. When UV light hits the dye, the individual molecules expand, darkening the lens and absorbing light. Coating contacts, however, doesn't work so well.


So researchers in Singapore have laced contacts with a matrix on nano tunnels filled with these photochromic dyes. Not only has the team been successful in producing transition contacts; these contacts darken in the presence of UV light faster than standard lenses (just 10 to 20 seconds).

Researchers are now working on isolating the photochromic material to just corneal region of your eye, granting you all of the UV filtering without turning your entire iris black.

Yeah, but do they allow you see through a woman's blouse? And, more importantly, can you believe I just said blouse? I don't even know what that is!
