Accent Eye Care Color Blindness, You Can’t See the True Colors

Color blindness occurs when you are unable to see colors in the usual way. It is also known as color deficiency. Color blindness often occurs when someone cannot distinguish between some colors. It usually happens between greens and reds, and occasionally blues.
The retina contains two types of cells that detect light. They are called rods and cones. Rods pick only light and dark; they are extremely sensitive to low light levels. Cone cells detect color and are mainly near the center of your vision. Three types of cones see color: red, green, and blue. Your brain uses input from these cone cells to determine your perception of color.
How does it happen?
It can happen when one or more of the color cone cells are absent, not working or detect an abnormal color. Severe color blindness occurs when all three cone cells are dysfunctional. Mild color blindness happens when all three cone cells are present though one cone cell does not work effectively. It detects a different color.
Variable degrees of color blindness
Some people with mild color deficiencies can see color in good light but have difficulty in dim light. Others cannot distinguish some colors in any light. The most severe form of color blindness, where everything appears in shades of grey, is uncommon. It usually affects both eyes equally and remains stable throughout life.
Color blindness is something that you have from birth but can also occur later in life. Change in color vision signifies a more severe condition. If you experience a significant variation in color perception, you should see an ophthalmologist.
There is no known cure for color blindness; contact lenses and glasses are available with filters to help color deficiencies.
