Sensory receptors in the skin have a different structure than sensory receptors in the eye. The most reasonable explanation for the difference in the structure of these receptors is that – there are many more sensory receptors in the skin than receptors in the eye.

only the sensory receptors in the eye transmit signals directly to the brain.

receptors in the skin are connected to nerve cells, but receptors in the eye are not.

receptors in the eye respond to a different type of input than receptors in the skin.
