5 Critical Facts about Color Blindness from Park Ophthalmology

Color vision plays a critical role in how people experience the everyday  world, whether it’s selecting fruits at the weekly Raleigh Downtown Farmers Market, or enjoying one of the many summer outdoor movie events in the Triangle. It is important to note that a small percentage of our Triangle population misses out on many experiences because they are color blind. Color blindness (also called color vision deficiency) makes average daily tasks such as driving, using computers and cooking much more difficult. Some patients have been helped with special contact lenses or eyeglasses that allow them to see color. Dr. Beth R. Friedland of Park Ophthalmology closely follows current research in Ophthalmology and her expertise brings the most current information and treatment to her patients.

Dr. Friedland offers five critical facts about color blindness:  

  • It is more common in men: Many more men than women are color blind. It is estimated that 1 in every 12 men and 1 in every 200 women are color blind.
  • It has a variety of causes: Color blindness is almost always hereditary, passed along from mother to son. It results when the color-receptors (cones) in the retina are either missing entirely or so few in number that it’s difficult to distinguish between red, green and blue. People are born color blind and the condition remains throughout life.
  • There are different types: There are different types of color blindness. Some people have less ability to see red; others have less ability to see green. Color blindness does not affect a person’s visual acuity.
  • It can affect children: It is important to check children for color blindness because the condition can affect their schoolwork. Color is used so frequently as part of the instruction in elementary school that color blind students will need extra help.
  • The diagnosis is straightforward: An ingenious method of testing for color blindness uses a selection of colored images. Hidden in the images are numbers or letters. Those with normal vision have no trouble seeing the number or letter. Doctors can determine what type of color blindness a person has by which images they are able to see on the test.

If color blindness is in the family, don’t put off having each child tested. Contact Park Ophthalmology today for an appointment and benefit from Dr. Friedland’s expertise in Pediatric Ophthalmology.
