It's called the blind spot - it can't detect light because there are no light sensitive receptor cells located here.
the answer is photoreceptors. search photoreceptors to figure out what they are.
There are two types called rods, which a simply sensitive to light and dark, and cones which are sensitive to colours. Both types are found on the retina but the rods dipsersed evenly over the surface whereas cones are concentrated on an area called the fovea.
The part of the eye which enables us to see colour are the millions of cones. Rods, on the other hand, enable night vision, but can only help one see black, white and shades of grey.
The cones in your retina (specialized nerve cells) detect different colours. This information is sent to your brain which interprets the information, allowing you to perceive certain colours.
cones
cones for color,rod are for black and white
The cones, located in the retina, detect color.
cones help us to see color
Cones help you see color and detail; rods see in black and white and detect movement in your peripheral vision.

There are two types called rods, which a simply sensitive to light and dark, and cones which are sensitive to colours. Both types are found on the retina but the rods dipsersed evenly over the surface whereas cones are concentrated on an area called the fovea.
The rods in the retina of the eyes are sensitive to low levels of light and movement. The cones are the ones that are sensitive to color and intensity, so the rods do not see color.
They fool your eyes - really your brain. Note that you don't see color, you detect frequency distributions (rods and cones of the retina) which your brain translates into colors for you.

Light travels through the pupil to the cones, which lie on the inside of the eye. It is these photoreceptors that allow the perception of color.
