Color blindness : Symptoms & Signs, Diagnosis & Tests
Symptoms & Signs
Symptoms vary from person to person, but may include:
- Trouble seeing colors and the brightness of colors in the usual way
- Inability to tell the difference between shades of the same or similar colors
Often, the symptoms may be so mild that some persons do not know they are color blind. A parent may notice signs of color blindness when a child is learning his or her colors.
Rapid, side-to-side eye movements and other symptoms may occur in severe cases.
Diagnosis & Tests
Your doctor or eye specialist can check your color vision in several ways. Testing for color blindness is commonly done during an eye exam.
