Color Vision Correction Contact Lenses
Yes, Contact lenses can correct Color Deficiency!
People who suffer from Color Vision Deficiency can still see the world in vibrant, accurate shades of color.
Specialty color blind contact lenses are designed to significantly improve color discrimination in color deficient wearers. Colorblind lenses contain a unique tint, which helps to improve the contrast between colors, by filtering the wavelength of each color you see.
While the lenses do not give the wearer perfect color vision, they allow people who have trouble distinguishing colors to see differences that previously looked similar.

These colors will be a dull yellow-brown, which can impede day-to-day activities like looking at traffic lights. It is the most common form of Color Vision Deficiency or Color Blindness.
Blue-Yellow Color-Blindness (Tritanopia) is less common. People affected confuse blue with green and yellow with violet.
Color Blind (Achromatopsia) is the truly colorless vision experienced as they see only white, black, or in shades of gray.
