If you have trouble seeing certain colors, your eye doctor can test to see if you have a color deficiency. You'll likely be given a thorough eye exam and shown specially designed pictures made of colored dots that have numbers or shapes in a different color hidden in them.
If you have a color vision deficiency, you'll find it difficult or impossible to see some of the patterns in the dots.
Computer or phone application tests can be useful for a quick color vision screening, but they may not be as accurate as standardized in-office testing.
