Question

Area of retina devoid of rods and cones is

• A. Yellow spot
• B. Blind spot
• C. Blue spot
• D. Black spot
• E. Red spot

Answer 1

The correct option is B Blind spot

Blind spot is the region in eye where no photoreceptor cells i.e. no cones and rods are present . It is the region from where optic nerve leaves the eye and retinal blood vessels enter the eye. The part of retina where these photoreceptor cells are absent forms the optic disc on which blind spot is present. The vision is nil in the region of blind spot.

So, the correct answer is 'Blind spot'.
