Optical system of human eye

WebApr 9, 2024 · The human eye operates similar to a digital camera in several ways: Light focuses mainly on the cornea, which acts like a camera lens. The iris controls the light that reaches the eye by adjusting the size of the pupil, and thus it functions like the diaphragm of a camera. The lens of the eye is located behind the pupil, and it focuses light.

WebThe optic disk, the first part of the optic nerve, is at the back of the eye. The photoreceptors in the retina convert the image into electrical signals, which are carried to the brain by the optic nerve. There are two main types of photoreceptors: cones and rods. WebEyes are organs of the visual system. They provide living organisms with vision, the ability to receive and 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 (neurones).
