Question 5 • Physicians, Pharmacists, Dentists, Veterinarians and Other Doctors

Which is true about color blindness?

Answer
A
It is genetic and caused by dysfunction or absence of specific types of cones.
B
It happens because of the shape of the eye, which makes the light fall wrong, causing the retina to be unable to translate the light into images.
C
It is caused by trauma to the optic nerve.
D
It is caused by watching too much TV and occurs in old age.

Explanation

Color blindness most often results from inherited changes that affect the cone cells in the retina. A person may lack a type of cone or have cones that do not function normally, making it harder to distinguish certain colors. Eye shape, optic nerve trauma, and watching TV are not the usual cause described here.
