Question

In your peripheral visual area (specifically 40° to the left of center), describe the density of retinal rods and cones.

Answer 1

The rods and cones are photoreceptor present in our human eyes .

These are peaked Maximum at the retina and will reduce in density towards the periphery.

At 40 degree angle vision the density of rods will be 30,000 to 40,000per mm². So the vision will decrease as it goes from centre to periphery.

The density of comes will be very few as it is maximum density at the center .

The vision at 40 degree will be normal but not that perfect and the colour cannot be detected properly
