Contact lenses may be useful for restoring vision to short- or long-sighted people, but not so much at correcting color blindness. Now researchers from the University of Birmingham have developed a contact lens that can help correct certain kinds of color blindness, thanks to a safe, low cost dye.

The O2Amps glasses from 2Al labs that were developed to help read people's emotions can also assist people with color blindness.
