X Chrom Contact Lenses for Colour vision deficiency
The X-Chrom lens is a monocular corneal contact lens which significantly enhances colour perception for those with a colour deficiency.
X-Chrom contact lenses are specialty contact lenses for colour 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 colour blindness, it only aids in the perception of colours.
