The ChromaGen lenses are prescription-only lenses and are available as eyeglasses or contacts in 16 subtly shades.

ChromaGen works by re-synchronizing and selectively changing the wavelength of light entering the eyes, thus correcting visual reading disorders and color blindness.

Cleared by the US Food and Drug Administration, the ChromaGen technology can be prescribed as a colored filter to aid individuals who experience reading discomfort and can be prescribed to enhance color discrimination in patients with color vision deficiencies.
