Question

Match the following eye defects with their remedial lenses.

• A. Concave lenses
• B. Cylindrical lens
• C. Convex lenses
• D. Bifocal lenses

Answer 1

Myopia is corrected using concave lens as it helps converge the light on the retina which was previously conversing in front of it. Astigmatism is corrected using cylindrical lenses. Hypermetropia is corrected using convex lens which moves the image to the retina which was earlier forming beyond retina. Presbyopia is corrected using bifocal lens i.e. a combination of a convex lens and a concave lens.
