How do the sclera and the cornea compare? The sclera is the inside layer at the back of the eyeball, and the cornea is on the outside of the eyeball. The sclera focuses light that enters the eye, and the cornea controls how much light enters the eye. The sclera does not allow light to enter the eyeball, and the cornea allows light to enter the eyeball. The sclera is the outer surface of the eyeball, and the cornea fills the inside of the eyeball.

Answer: The sclera is the outer surface of the eyeball, and the cornea fills the inside of the eyeball.

The eye is protected by tough white sac which is called as sclera. The cornea is the transparent membrane layer in the sclera which allows the light inside the eye. The surface of the cornea allows observation of object from the light.

Answer: The Sclera does not allow light to enter the eyeball, and the cornea allows light to enter the eyeball.

Explanation:

Cornea is part of Sclera. Sclera is the white outer covering of eye ball. Cornea is the curved layer in front of iris and pupil through which light enters the light and focuses on retina at the back of the eye. Hence, the correct comparison between Sclera and cornea from the given options would be that cornea allows light to enter the eyeball but Sclera does not.
