At first glance, “color blindness” (more accurately described as “color vision deficiency”) is more of a quirky happenstance than a real problem. However, when one considers how many color cues we must pay attention to in order to successfully navigate our personal and professional lives, the inability to distinguish certain colors presents itself as no small matter. While it is very rare that a person does not see any color at all (achromatopsia), some people do not realize that they see colors incorrectly until they undergo an eye exam. The inability to distinguish colors is almost always hereditary, but color deficiency may also result from retinal disease or other eye disorders or be a side effect of certain medications. Color blindness is typically inherited and means that you have trouble seeing red, green, or blue or a mix of these colors.There is no cure for inherited color deficiency. People learn to distinguish colors in other ways and/or may use tinted glasses.
