Eyes are the windows to soul. Human eyes are considered as a most important organ of our body. With these beautiful eyes, one can see the beautiful creation of God – that is nature, universe etc.
Eyes are organs of the visual system. They provide organism’s vision, the ability to process visual detail, as well as enabling several photo response functions that are independent of vision.
Eyes detect light and convert it into electro-chemical impulses in neurons.
In higher organisms, the eye is a complex optical system which collects light from the surrounding environment, regulates its intensity through a diaphragm, focuses it through an adjustable assembly of lenses to form an image, converts this image into a set of electrical signals, and transmits these signals to the brain through complex neural pathways that connect the eye via the optic nerve to the visual cortex and other areas of the brain.
