What is Color Blindness?
Color Blindness or color deficiency is when a person cannot distinguish between shades or colors (most often between greens, reds, and sometimes blues). The retina in your eye has a cell that is made up on 3 cone cells. These cells detect color and determine our color perception. The three types of cone cells are red, blue, and green. The brain obtains input from these cone cells to detect color and determine our color perception. When one or more of these cells are absent, Color Blindness may occur. The severity of Color Blindness is affected by the number of cone cells absent or not working. Source: AAO

Treatment
There is no current treatment for color vision deficiency. However, people find that there are glasses/contacts that have been reported to help differentiate hues and perceptions. If you have experienced a significant change in color perception, please consult with an ophthalmologist as it may indicate a more serious condition.
