Inventor Chris Mullin constructed these electronic sunglasses, which detect bright objects in your view and selectively darken them by turning on part of an LCD screen. He got the idea while commuting to a job that required him to drive towards the sun. The project is still in prototype phase, but he has a kickstarter set up to raise money to bring them into production.
I’ve been wanting something like this for my camera lens, but never thought about putting it on a pair of glasses. Great idea! [via Yanko Design]
