The eyeball is attached to the orbit by muscles.

The conjunctiva secretes tears.

The choroid is richly supplied with blood vessels.

Which of the following statements about the eye structures is correct?

There is blood supply to the cornea.

Which of the following statements about the eye structures is incorrect?

Structure A is made up of living cells without nuclei.

Structure B can refract light onto the retina.

Structure C possesses a high density of rod cells but no cone cells.

Which of the following statements about the eye defects is correct?

Short sight occurs in young people only.

Short sight can be corrected by wearing spectacles with convex lenses.

Colour blindness can be prevented by taking in adequate vitamin A.

The light rays from near objects are focused behind the retina in long-sighted people.
