Light focus automatically increases on nearby objects

The eye is an organ of the visual system. They provide animals with vision and the ability to receive and process visual details, as well as enable many vision-independent image response functions. The eyes detect light and convert it into chemical electrical impulses in nerve cells. In higher organisms, the eye is a complex optical system that collects light from the surrounding environment, regulates its intensity through a membrane, focuses it through 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 pathways A complex nerve that connects the eye via the optic nerve to the visual cortex and other areas of the brain. Analytical eyes come in ten fundamentally different shapes, and 96% of animal species possess a complex visual system.
