Please answer this question number 14 with explanation....
Dear student,
14. With age, the eye lens loses its elasticity, and thus its becomes hard to change the focus, which leads to Presbyopia.
This defect can be corrected using bifocal glass, where the upper part is made of a concave lens that helps to see a distant object clearly and the lower part is made up of a convex lens, that helps to focus on the nearby objects.
Option b. Bifocal lens
Regards
