There are different types of color blindness related to the malfunction of different types of cones. Why would it be particularly useful to study those rare individuals who are color blind only in one eye or who have a different type of color blindness in each eye?
Studying the same person with different color vision in the different eyes will give us more opportunities to understand the working of the eye
Color blindness occurs when you are unable to see colors in a normal way. It is also known as color deficiency. Color blindness often happens when someone cannot distinguish between certain colors. This usually happens between greens and reds, and occasionally blues.
If we study the person having color blindness in one eye or having a different type of color blindness in two different eyes, then we can compare the function of the eye in a much better way.
Since the perception of color is subjective and different people may view color differently, comparing the color vision of two-person may not give us desired result. But studying the same person with different color vision in the different eyes will give us more opportunities to understand the working of an eye.
It has become common to replace the cataract-clouded lens of the eye with an internal lens. This intraocular lens can be chosen so that the person has perfect distant vision. Will the person be able to read without glasses? If the person was near-sighted, is the power of the intraocular lens greater or less than the removed lens?
