Verified step by step guidance

Begin by understanding the anatomy of the eye, specifically the retina. The retina is the light-sensitive layer at the back of the eye that contains photoreceptor cells.

Identify the role of the optic nerve. The optic nerve is responsible for transmitting visual information from the retina to the brain.

Locate the blind spot, also known as the optic disc. This is the area on the retina where the optic nerve exits the eye.

Recognize that the blind spot lacks photoreceptors, meaning it does not contribute to vision. This is why it is called a 'blind spot.'

Understand that the fovea centralis is a different part of the retina, responsible for sharp central vision and contains a high concentration of photoreceptors, unlike the blind spot.
