Question

a) What is the function of rods and cones in our eye?
b) What is blind spot? ​

Answer 1

Answer:

a) Rods are responsible for vision at low light levels (scotopic vision). They do not mediate color vision, and have a low spatial acuity. Cones are active at higher light levels (photopic vision), are capable of color vision and are responsible for high spatial acuity.

b) Blind spot, small portion of the visual field of each eye that corresponds to the position of the optic disk (also known as the optic nerve head) within the retina. There are no photoreceptors (i.e., rods or cones) in the optic disk, and, therefore, there is no image detection in this area.

Answer 2

Answer:

Blind spot is a small area of the retina insensitive to light where the optic nerve leaves the eye
