Can you develop color blindness as you grow older?

Kind of: Agree with dr. Deluise, but would also add that any problem of the optic nerve such as naion, or optic neuritis that can happen later in life can also affect your color vision. Certain medicines also have color vision related side effects.

Yes but unlikely: The typical genetic color vision anomalies are present from birth, and the types that happen later in life are usually related to an acquired damage to the retina or optic nerve. Plaquenil (hydroxychloroquine) is a drug that can cause color vision defects in some patients after many years of use.
