Which organ is responsible for vision?

The eyes are the organs responsible for vision because they contain specialized cells known as photoreceptors, which detect light and convert it into visual information. The process begins when light enters the eye through the cornea, passes through the lens, and then is focused onto the retina, where these photoreceptors are located. The retina converts this light into electrical signals that are sent to the brain via the optic nerve.

The brain plays a crucial role in processing visual information but does not directly participate in the act of vision itself; it interprets the signals received from the eyes. The ears are associated with hearing and balance, while the nose is involved in the sense of smell. Each of these other organs serves its distinct sensory function, but only the eyes are directly engaged in the process of vision.
