The blind spot is the area on the retina where the optic nerve exits the eye, and it does not have any photoreceptor cells, so images formed here cannot be seen.

What do rods do in the eye?

Back

Rods are photoreceptor cells that allow us to see in dim light and are responsible for black and white vision.

Front

What is the lens of the eye?

Back

The lens is a transparent structure that focuses light onto the retina.
