A. Convex lenses
B. Concave lenses
C. Contact lenses with astigmatism correction
D. Bifocal lenses

Answer

Concave lenses

Explanation

Concave lenses are used to diverge light rays before they enter the eye, helping to focus distant objects correctly on the retina.

Common mistake

Misunderstanding Myopia

Students often think that myopia is caused by the eye being too long rather than understanding that it is due to distant objects being focused in front of the retina.

Clarify that myopia occurs when the light rays from distant objects converge before reaching the retina, leading to blurred vision for far away objects.
