What is the function of the eyes?

The eyes are the sense organs responsible for vision. Their main function is to detect light and help humans see objects, colors, shapes, distance, and movement.

The eyes collect visual information from the surroundings and send it to the brain through the optic nerves. The brain then interprets these signals to form images.
