Detailed explanation-1: -An eyespot (sometimes ocellus) is an eye-like marking.

Detailed explanation-2: -Blind spot is the region where the optic nerve passes through the optic disk and out of the eyes. Also, it is at this very region that the blood vessels enter the eyes. It lacks photoreceptor cells (rods and cones) in the retina so the light falling at this spot does not form any image.

Detailed explanation-3: -When the light enters the human eye through the cornea, it then passes through the aqueous humor, the lens and the vitreous humor. Then the image is formed on the retina of the eye.

Detailed explanation-4: -Everyone has a spot in their retina where the optic nerve connects. In this area there are no light-sensitive cells so this part of your retina can’t see. We call this the blind spot.
