Are you Color Blind?


Color blindness occurs when you or someone you love is unable to see colors in a normal way. It is also known as color deficiency. Color blindness often happens when someone cannot distinguish between certain colors. This usually happens between greens and reds, and occasionally blues. In the retina, there are two types of cells that detect light. They are called rods and cones. Rods detect only light and dark and are very sensitive to low light levels. Cone cells detect color and are concentrated near the center of your vision. There are three types of cones that see color: red, green and blue. The brain uses input from these cone cells to determine our color perception.

Color blindness can happen when one or more of the color cone cells are absent, not working, or detect a different color than normal. Severe color blindness occurs when all three cone cells are absent. Mild color blindness happens when all three cone cells are present but one cone cell does not work right. It detects a different color than normal. There are different degrees of color blindness. Some people with mild color deficiencies can see colors normally in good light but have difficulty in dim light. Others cannot distinguish certain colors in any light. The most severe form of color blindness, in which everything is seen in shades of gray, is uncommon. Color blindness usually affects both eyes equally and remains stable throughout life.

Take a look at these images and see if you can easily distinguish between the colors and what each circle contains.


We work with a Bay Area company that is helping people conquer color blindness and helping adults see colors they have perhaps spent their entire life missing. EnChroma created the new frontier in color vision technology. Their color blind glasses are uniquely engineered to give those with color blindness the ability to see more of the broad spectrum of bright colors most of us take for granted. Utilizing a patented light filter technique, EnChroma lens technology is applied with mathematical precision to address common forms of red-green colorblindness.

If you or a loved one had trouble reading the circles above, make an appointment with one of our optometrists and we can help get you a pair of Enchroma glasses that will work to help you see the world as vividly as you can.
