Introduction

Poor color vision is an inability to distinguish among certain shades of color. Although most people call it colorblindness, true colorblindness describes a total lack of color vision. The ability to see only shades of gray is rare.

Most people with poor color vision can't distinguish between certain shades of red and green. Less commonly, people with poor color vision can't distinguish between shades of blue and yellow.

Poor color vision is an inherited condition in most cases. However, eye diseases and the effects of some medications also can cause color deficiency. Men are more likely to be born with poor color vision.
