What is Color Blindness?



Men have often been accused of being color blind by women for their inability to distinguish slight differences in certain hues of colors, such as the difference between periwinkle and powder blue. Yes, this is a tragedy. However, this has more to do with not knowing—or caring—what the different shades of blue are. Color blindness is a real medical condition where the afflicted have an inability to see colors in the usual way.

People suffering from color blindness often have a difficulty seeing red, green, or blue, or a mix of these colors. It is very rare for someone to not be able to see any colors at all.

Most color vision problems are genetic and are often diagnosed during childhood. People have three types of cone cells in their eyes that sense red, blue, and green light. Inherited color blindness may result from a lack of one of these cone cells or they are not working properly. However, color vision problems can also result from:

           *Injuries to the eye
           * Aging
           *Side effects from medication
           *Eye conditions such as cataracts, glaucoma, and macular degeneration.

Those suffering from color blindness might have difficulty distinguishing the number in the image above. If you can’t decipher what the number is in the circular image you may want to consult an eye care professional.

For children that are suspected of having color blindness tests are typically conducted between the ages of 3 to 5 years old. For children, it is important to diagnose color blindness as soon as possible since color vision can affect learning abilities and reading development.

If you think you or your child might have color blindness or a color vision problem please contact Vision Pro to set up an appointment with one of our eye care professionals. We would be more than happy to help you on your way to healthy vision!
