Color Deficient Contact Lens
The X-Chrom lens is a monocular corneal contact lens which significantly enhances color perception for those with a color deficiency.
X-Chrom contact lenses are specialty contact lenses for color blindness. A deep red tinted X-Chrom contact lens is worn in the nondominant eye and intensifies the color of red and green objects.
This lens does not cure the vision problem of color blindness, it only aids in the perception of colors.
