If photoreceptor cells of the retina are damaged, why will vision be affected?
Answer and explanation
Correct answer: Because they convert light into nerve signals
Photoreceptors are specialised cells in the retina. Rods and cones absorb light and convert it into electrical nerve signals, which are processed and ultimately carried to the brain through the optic pathway. If these cells are damaged, the first stage of visual signal formation fails, so vision becomes impaired. The other options describe unrelated functions.
