Function of the eye cornea

Answer 1

Because the cornea is as smooth and clear as glass but is strong and durable, it helps the eye in two ways 1. It helps to shield the rest of the eye from germs, dust, and other harmful matter. The cornea shares this protective task with the eyelids, the eyesocket, tears, and the sclera, or white part of the eye 2. The cornea acts as the eye's outermost lens. It functions like a window that controls and focuses the entry of light into the eye. The cornea contributes between 65-75 percent of the eye's total focusing power. When light strikes the cornea, it bend-or retracts-the incoming light onto the lens. The lens further refocuses that light into the retina, a layer of light sensing cells lining the back of the eye that starts the translation of light into vision. For you to see clearly, light rays must be focused by the cornea and lens to fall precisely on the retina. The retina converts the light rays into impulses that are sent through the optic nerve to the brain, which interprets them as images

Answer 2

The cornea is the transparent front part of the eye that covers the iris, pupil, and anterior chamber. Together with the lens, the cornea refracts light, accounting for approximately two-thirds of the eye's total optical power. In humans, the refractive power of the cornea is approximately 43 dioptres. While the cornea contributes most of the eye's focusing power, its focus is fixed. The curvature of the lens, on the other hand, can be adjusted to "tune" the focus depending upon the object's distance. (Wikipedia)

Answer 3

The cornea is a continuation of the sclera in the front of the eye. It is non-vascular, transparent, non-fibrous and white in colour. It is curved and it refracts light due to this

nature and the rays bend. It consists of a circular window in the middle called pupil which regulates the amount of light entering the eye. Corneal ulceration is caused by the absence of thiamine in the diet.

Answer 5

The cornea serves as a protective outer layer of the eye, helping to focus light and providing most of the eye's refractive power. It plays a key role in the eyesight by bending or refracting light as it enters the eye.

Answer 6

It is the part of your eye which picks up light rays, so it basically allows you to see.

Answer 7

The cornea refracts light.
