What is Color Blindness?
People who are color blind are actually color deficient and lack the ability to distinguish certain colors from each other. The most common form of color blindness is a red-green deficiency. This type of color deficiency is classified as deuteranopia or deuteranomaly.
Those who are color deficient are unable to see certain colors under normal light.
Who is Affected?
Millions of people worldwide are affected by color blindness. 8% of American males are color deficient. 0.5% of females are color deficient. That’s 1 in 12 men and 1 in 200 women. There are a variety of color deficiencies, but red-green is the most common.
People tend to think that those who are color blind see only black and white. Color blindness actually describes a diminished ability to see colors, which results in seeing variations of brown. Folks who see only black and white shades are monochromats and have poor overall vision, but this is a rare condition.
Most color blindness is inherited genetically. Women are the carriers of the genetic condition and it is carried on the X chromosome. There are medical conditions and diseases that cause acquired color vision deficiencies.
Symptoms and Causes of Color Blindness
Red-green color deficiency is the most common and these people see the world differently. Their red and green photopigments overlap abnormally making it difficult to distinguish colors from each other.

Solving the Problem
EnChroma functions similar to antibiotics when you are sick.
Antibiotics work by attacking specific bacteria that are making you ill. EnChroma works by using a filter to target certain photopigments that cut out select wavelengths of light to enhance specific colors.
This patent-pending method is called ‘multinotch’ filtering. EnChroma lenses divide the overlapping red and green colors, thereby improving vision for this type of color deficiency.
Are EnChroma Lenses Available in Prescription?
EnChroma is available in single vision, bifocals and progressive lenses. We can conveniently design EnChroma lenses to fit nearly any of the 2500 frames in our upscale showroom.
