Chapter 16, Problem 10TYR
Summary Introduction
Introduction:
The perception of items that are present in the surroundings is termed as sight or vision. This perception occurs by means of reflection or emission of light from those objects. The retina (the neural component) is one of the principle components of the eyeball. It consists of three cell layers and these cell layers are composed of ganglion cells, bipolar cells, and photoreceptor cells.

An individual has 50% less than the normal number of green cone photoreceptors in his or her retina. How would this affect his or her vision? a. This person has night blindness. He or she should start to eat more carrots to replenish the stock of retinal molecules in the retina. b. This person will have difficulty adapting to varying light levels. His or her cone receptors take much longer to adapt in a brightly lit area. c. This person does not have a colour blindness because no green cone photoreceptors are in the retina; only red, yellow, and blue photoreceptors exist. d. This person has a mild green colour blindness. He or she cannot see green colours very clearly and has difficulty distinguishing colours involving green hues.arrow_forwardWhich of the following statements explains why vision is less sharp in dim light than in bright light?a.
