Color Blind Testing

Color blindness is not a form of blindness at all, but a deficiency in the way you see color.

Color Blindness

Color blindness is not a form of blindness at all, but a deficiency in the way you see color. With this vision problem, you have difficulty distinguishing certain colors, such as blue and yellow or red and green.Color blindness (or, more accurately, color vision deficiency) is an inherited condition that affects males more frequently than females.

Contrary to popular belief, it is rare for a color blind person to see only in shades of gray.  Most people who are considered "color blind" can see colors, but certain colors appear washed out and are easily confused with other colors, depending on the type of color vision deficiency they have.

Color Blind Testing

  • Ishihara Color Vision Plates:  Patients are given a book and are instructed to call out the number or symbol that they see. 

  • Computerized Color Hue Test: Patients are presented with numbers in different hues and patients select what number they see.

Treatments for Color Blindness

Patients with color vision deficiencies have two options they can get Chromagen contacts and glasses.  These products are made with different color filters to reverse the color deficiencies.
