The retina contains millions of specialized light-sensitive cells called photoreceptors. When light strikes these photoreceptor cells, it triggers chemical and electrical signals which are transmitted to the brain via the optic nerve. The brain receives these electrical signals and processes them into the images we perceive. It also combines the input from both eyes to create depth perception, which allows us to judge distances accurately.
