A new type of contact lens could help people living with color blindness. Researchers say that they could help people with a form of red-green color blindness. The contact lenses restore lost color contrast. The research was published in The Optical Society journal Optics Letters.
"Glasses based on this correction concept are commercially available, however, they are significantly bulkier than contact lenses," said Sharon Karepov, a member of the research team, said. "Because the proposed optical element is ultrathin and can be embedded into any rigid contact lens, both deuteranomaly and other vision disorders such as refractive errors can be treated within a single contact lens."
