Question

If a person with long sightedness is given spectacles with concave lenses, will he/she have a
clear vision? Justify.
​

Answer 1

Answer:

Myopia occurs when the light is focused in front of the retina. It occurs because either the eyeball is too long, or because the cornea is too curved. People with short sight are not able to see distant objects clearly. Concave prescription lenses (called as minus lenses) are used to bend light rays slightly outwards. The light rays then have a greater angle to bend back to focus when traveling through the cornea and lens. As a result, the light rays focus further back on the retina.

So, the correct answer is option C.
