Sunglasses designed to clear things up for the color blind

Upcoming sunglasses promise to make traffic signals and picking out ripe fruit easier for people with color blindness.

Color blindness, also known as color vision deficiency, is not an issue I've had to deal with. In fact, it's not something that crops up in women much. Statistics show about 1 in 10 men have some form of color blindness, so if you're not color blind yourself, you probably know someone who is.

That means there's a good chunk of the population that wouldn't mind a little assist in the color department. This is where sunglasses maker EnChroma hopes to make its mark.

EnChroma produces lenses with special optical coatings that selectively filter the light coming through to enhance the wearer's view of colors.

If these glasses work as advertised, it could help people with color blindness read things like traffic signals and fashion cues more accurately.

The idea came out of work in developing custom protective eyewear for laser surgeons. The Enchroma Cx line comes in several different versions for those with regular sight; folks with deuteranomaly (red/green blindness); and people with protanomaly (red weakness).

Perhaps the best thing about these glasses is that they will be available with Buddy Holly frames so you can be high-tech without sacrificing your charmingly nerdy look. Pricing is not yet announced, but the sunglasses will be available this fall.
