What part absorbs light and converts it into nerve impulses
What part bends light that enters the eye so that what you see is focused on your retina
What part transfers the image the eye sees to the brain for perception
Look on most diagrams of the eye.
Rods and cones
Cornea and lens
optic nerve
The part of the eye that absorbs light and converts it into nerve impulses is called the retina. The retina is located at the back of the eye and contains specialized cells called photoreceptors (specifically rods and cones) which are sensitive to light. When light enters the eye and reaches the retina, these photoreceptor cells convert the light into electrical signals or nerve impulses. These impulses are then sent to the brain through the optic nerve for further processing and interpretation.
The part of the eye that bends light to focus it on the retina is called the lens. The lens is a transparent, flexible structure located behind the iris and the pupil. Its main function is to refract or bend the incoming light rays so that they converge and form a focused image on the retina. The shape of the lens can be adjusted by the ciliary muscles surrounding it to allow for proper focusing on objects at different distances.
The part that transfers the image from the eye to the brain for perception is the optic nerve. Once the electrical signals or nerve impulses are generated in the retina, they travel through the optic nerve, which is a bundle of millions of nerve fibers. The optic nerve carries these signals from the eye to the primary visual processing areas in the brain, where they are further processed and interpreted to form the visual perception of the image being seen.
