Eyes Wallpapers

They 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

Eyes with resolving power have come in ten fundamentally different forms, and 96% of animal species possess a complex optical system

Image-resolving eyes are present in molluscs, chordates and arthropods
