Contact Lenses that Respond to Light

My group and I did our technology pitch on contact lenses that respond to UV light. They are similar to the transition eyewear that has been around for 30 years or so now. The UV responding contact lenses are being researched by The Institute of Bioengineering and Nanotechnology in Singapore and might be on the market in Japan and Korea in one year. I do not wear glasses or contact lenses myself, but I think it would be a great thing to have in order to protect your eyes from the sun. Athletes who prefer to wear contact lenses over glasses would benefit greatly from transition contact lenses. It is hard for football players to wear glasses with their helmets, so most wear contact lenses. The sun can still interfere with the player's game though. But with transition contact lenses, the lense would respond to the UV light within 30 seconds and protect the player's eyes. Anyway, it will be interesting to see how these turn out...
