Tests and diagnosis
By Mayo Clinic staffIf you have trouble seeing certain colors, your eye doctor can quickly and easily test to see if you have a color deficiency. Many specialists trained in diseases and disorders affecting the eye use a book containing several multicolored dot-pattern tests to provide a simple and accurate assessment of color vision deficiencies inherited at birth. If you don't have a color vision deficiency, you'll be able to pick out numbers and shapes from within the dot patterns. However, if you do have a color vision deficiency, either you'll find it difficult to see anything among the dots, or you won't see anything at all.
