The region of vertebrate eye, where optic nerve passes out of retina, is called

The correct answer is Blindspot.

Key Points

• Blindspot: It is that part of the vertebrate eye, where the optic nerve connects to the retina.
  • It does not have receptors that respond to light.
  • It is composed of nerve fibres that do not have the ability to reconstruct on their own. 

Additional Information 

• Fovea: It is a tiny pit located in the retina that provides the clearest vision.
  • Here, the light falls directly on the cones because of which the cone cells give the sharpest image. 
• Iris: It regulates the size of the eye and controls the amount of light entering the eye.
  •  Pigments in the iris help in creating the colour of the eye.
• Optic chiasm: It is a region in the eye where photoreceptors are absent.
