Color blindness is a form of color vision deficiency; the most common is the issue of distinguishing between red and green.
Berkeley, CA-based EnChroma found a fix that can help people see more color. Dr. Don McPherson the chief scientist of EnChroma calls the invention of glasses curing the color blindness is accidental.
EnChroma sells glasses for outside and inside and they have a variety of frames to choose from, the company has since sold nearly 30,000 sunglasses and indoor glasses to people around the world. A pair cost about $300 and up depending on whether a prescription is added.
EnChroma is working on new technology to help all types of color deficiencies. McPherson said they are also in the process of developing contact lenses.
