For the people with poor eyesight, the video-glasses-looking device called SightMate can improve the sight, featuring a 2 megapixel camera with a 3x zoom placed in the middle of the outer frame. The glasses sport two 640×480 displays that get images from the camera.

Also, the SightMate can compensate colorblindness, getting people vision of 20/20 to 20/40 from 20/70 and 20/200 accuity. Unfortunately, the device is quite expensive and there’s a notice that you shouldn’t use it while driving. You can already order it for $3,500.
