How Color Blindness Works

Color deficiency, more commonly referred to as color blindness, is an optical condition in which affected people have a deficiency in one or more of the primary colors (red, green, or blue) recognized through the retina. On a deeper level: color blindness stems from an absence, mutation, or weakness in your retinal cones.

"L-cones"

Respond to long wavelengths (or 'red' wavelengths)
64% of the cones are red-sensitive

"M-cones"

Respond to medium wavelengths (or 'green' wavelengths)
32% of the cones are green-sensitive

"S-cones"

Respond to short wavelengths (or 'blue' wavelengths)
2% are blue-sensitive

How Your Eyes Perceive Color

The retinas in both of your eyes contains a collection of rods and three different types of cones with photo-pigments that sense different portions of the spectrum. Each cone is tuned to distinguish different wavelengths of light and when all cones are functioning normally an individual will not experience any form of color blindness or color deficiency.

ChromaGen lenses enhance color perception and discrimination by using selective wavelengths of light to stimulate defective cone cells which allows the patient to more accurately interpret and perceive color.

Once the appropriate ChromaGen lenses are prescribed for each eye, an individual that was unable to pass a standard color deficiency test is now able to interpret and perceive colors in the correct fashion and experience the full color spectrum.

Types of Color Blindness

Color blind individuals are generally grouped into three main categories.
