What does it mean to be color blind?
The term “color blindness” is actually a bit of a misnomer. A person who is labeled as color blind can appreciate color; however, he perceives them differently than the average person. A color blind person will still call a red flower “red” because that’s what he was taught “red” looks like. However, what the color looks like to him is actually quite different. Color blindness is usually present from birth and tends to run in families.
What if my color vision changes?
If you have a change in your perception in color or if your Optometrist finds a change in your color vision upon testing, this may be an indicator of eye disease. Changes in color vision often accompany cataracts, macular degeneration and optic nerve disease.
