Damage to the fovea of an eye?

Question

Would that result in

A) Diminished ability to focus

B) Lack of ability to see color

C) Diminished ability to regulate the amount of light striking the retina.

I want to say A but am I right??

Answer 1

there are cones and rods in your retina. the cones allow us to see in color, while the rods allow us to see black and white.

the fovea maculae contains the cones so your answer is B.

Answer 2

b  The fovea is where the cone cells are located.

Answer 3

The fovea is densely packed with cone cells which are not only responsible for colour vision but also give us our ability to focus and make out fine detail. So I'd pick answer A.

Foveal damage can result in distortion of colour vision, however as cone cells are present not only in the fovea but throughout the entire retina (albeit more sparsely), it wouldn't result in a complete lack of ability to see colour.

Hope this helps.
