Question

What are rods and cones in the retina of an eye ? Why is our night vision relatively poor compared to the night vision of an owl ?

Answer 1

Rods are the rod-shaped cells present in the retina of an eye which are sensitive to dim light. Cones are the cone-shaped cells present in the retina of an eye which are sensitive to bright light.

Our night vision is relatively poor compared to the night vision of an owl due to the presence of relatively smaller number of rod cells in the retinas of our eyes.
