Blind spot: 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.
Yellow spot: The yellow spot, also known as macula, is the centre of the eye and sharpest sight place.

1. These spots absorb blue and UV light entering the eye in excess.
2. They are not sensitive to light. 2. They are sensitive to light.
3. It is this very region wherein the main blood vessels supplying blood to the retina enter. 3. These regions are involved in high resolution vision, possible in a fair amount of light.
