among the 5 senses of humans Explanation: Sight Sight, or perceiving things through the eyes, is a complex process. First, light reflects off an object to the eye. The transparent outer layer of the eye called the cornea bends the light that passes through the hole of the pupil. The iris (which is the colored part of the eye) works like the shutter of a camera, retracting to shut out light or opening wider to let in more light. "The cornea focuses most of the light. Then, it [the light] passes through the lens, which continues to focus the light," explained Dr. Mark Fromer, an ophthalmologist and retina specialist at Lenox Hill Hospital in New York City. [How the Human Eye Works] The lens of the eye then bends the light and focuses it on the retina, which is full of nerve cells. These cells are shaped like rods and cones and are named for their shapes, according to the American Optometric Association. Cones translate light into colors, central vision and details. The rods translate light into peripheral vision and motion. Rods also give humans vision when there is limited light available, like at night. The information translated from the light is sent as electrical impulses to the brain through the optic nerve. People without sight may compensate with enhanced hearing, taste, touch and smell, according to a March 2017 study published in the journal PLOS One. Their memory and language skills may be better than those born with sight, as well. "Even in the case of being profoundly blind, the brain rewires itself in a manner to use the information at its disposal so that it can interact with the environment in a more effective manner," Dr. Lotfi Merabet, senior author on that 2017 study and the director of the Laboratory for Visual Neuroplasticity at Schepens Eye Research Institute of Massachusetts Eye and Ear, said in a statement.
