The cornea is a tough, clear covering that keeps objects from entering the pupil.
The Cornea is the front part of the eye that covers the iris and the pupil.
help keep your eye clean
Keeps dirt , germs and grit out of your eye it is like the protective cover for your eye.
It refracts light together with the lens.
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

The cornea focuses the light from the object you are looking at into the pupil, where the image gets processed on the retina.
If I'm not mistaken, the cornea is the colorful ring surrounding the iris? I was told the cornea are the muscles that control dilation of the iris, controlling the amount of light that is allowed to enter the eye.
The reason it is colored is due to genetics. Specific amino acids produce different colors (including people like myself who's color changes, which is affected by additional acids in the food we eat).
cornea is transparent layer forming the front of eye.
Consists of the cornea and sclera. The fibrous tunic is the outer layer of the eye.
No because the cornea helps the eye to focus on objects and keeps dust and germs out of the eye.
The clear part of the eye is called the cornea. It is the front section of the eye that is a covering for eye parts like the iris and anterior chamber.
The sclera is double the thickness of the cornea. The center of the cornea is thinnest, followed by the periphery, then sclera.
Sclera
The primary function of the cornea's curved surface is to bend light rays to focus them on the retina.
The cornea is avascular because it must be basically transparent in order to function.
Consists of the cornea and sclera. The fibrous tunic is the outer layer of the eye.
So the Frog has the ability to see
No because the cornea helps the eye to focus on objects and keeps dust and germs out of the eye.
it is the covering over the eye and it protects the eye from germs on your eyelids and from the air
The corneal endothelium governs fluid and solute transport across the posterior surface of the cornea and actively maintains the cornea in the slightly dehydrated state that is required for optical transparency.
what is the cornea and what does it do
No, the anterior part of the cornea does not function as a contact lens. The cornea is the clear, dome-shaped front part of the eye that helps to focus light onto the retina. Contact lenses are external devices that are placed directly onto the cornea to correct vision or change its appearance.

welll it is the lower cornea
