• question_answer For the myopic eye, the defect is cured by :- A)  Convex lens       B)  Concave lens             C)  Cylindrical lens   D)  Toric lens

In myopia, $u=\infty ,$v=d=distance of far point By $\frac{1}{f}=\frac{1}{v}-\frac{1}{u},$ we get $f=-d$ Since f is negative, hence the lens used is concave.
