What is Color Blindness?
Color blindness is often an M-L color shift or overlap issue. This is an excessive overlap of the M (green) and L (red) color cones in the eye. This overlap obscures a range of color hues and makes them hard to discern. A color blind person may see as little as 10% of the color shades that people with normal vision can see.
Treating Color Blindness
Defective color vision, often referred to as color blindness, ranges from a mild to severe inability to distinguish different color groups or shades. Red-green color deficiencies are the most common, but blue-yellow defects also occur.
Most color vision defects are inherited and affect both eyes. Some color vision loss can be due to diseases that damage the retina, optic nerve or other parts of the visual system. These defects may affect one or both eyes.
How Enchroma Works
Science & Lens Technology
EnChroma made lenses that filter wavelengths of light just where the color overlap happen. The results is that M and L cones are altered for a greater color discrimination.
Your doctor may test color vision as part of your eye examination, since changes in color vision offer important diagnostic information in a number of eye diseases. Many patients with color vision defects experience problems with work or even normal activities like driving where accurate color differentiation is critical.
