Colorblindness FAQs in Spartanburg, SC

Colorblindness is not "blindness" but simply the failure of photopigments (due to genetic abnormalities) to correctly differentiate various shades of blues, greens, reds, and yellows. Your Spartanburg optometrists diagnose color blindness using standardized color vision tests and can treat colorblindness by prescribing corrective lenses that make it easier to discern colors.

What is Colorblindness?

Colorblindness is a hereditary eye disorder interfering with one’s ability to distinguish certain colors from other colors; color blindness involves genetic defects in specialized pigments that undergo chemical changes after absorbing light. These cone-shaped photopigments are found only in the retina and support the perception of visual and color details.

Is Color Blindness a Strictly Inherited Disorder?

The majority of people diagnosed with colorblindness have simply inherited this problem. In some cases, eye diseases, injuries, and aging can disrupt the functioning of retinal photopigments and cause color blindness. Diabetic retinopathy, cataracts, macular degeneration, and glaucoma are a few eye diseases that may promote the development of color blindness.

What is Red-Green Color Blindness?

Red-green color blindness is diagnosed in more boys than girls and is the most common type of colorblindness. People with red-green colorblindness have abnormal red photopigments that make red, orange and yellow seem greenish and greener than other colors.

If a person has little to no properly functioning red cone cells, they will see lighter shades of orange and green as yellowish. Defective green cone cells cause you to see greens and brownish-yellows as beige, tan or light brown. Abnormal green photopigments will make it difficult to differentiate between blues and violets while greens and yellows appear reddish.

What is Blue-Yellow Color Blindness?

Less common than red-green color blindness is blue-yellow color blindness, a disorder affecting blue cone photopigments. Someone with blue-yellow colorblindness may perceive blues as green and have trouble distinguishing red and yellow from pink. In addition, some people with blue-yellow color blindness may be unable to tell the difference between yellows and violets.

What Treatment is Available for Colorblindness?

Our eye doctors in Spartanburg can prescribe lenses to help differentiate colors in bright light conditions. There are also smartphone visual aid apps for colorblind people that allow them to see colors correctly through a photograph. Other useful apps offer information about primary colors and different shades of these colors to help colorblind people select ripe fruits and vegetables or matching and complementary clothing colors.

  • "I was notified that my glasses were ready for pick up. I went to the office without an appointment and the receptionist directed me to the appropriate area. I received my glasses, had a minor adjustment made by the technician, and was out the door 10 minutes after arriving! Great staff and great service."
