Convex lenses cause the focal point to appear behind the lens (positive convergence). In myopia, the focal point lies somewhere between the lens and the retina, it needs to converge at a point farther than it is converging, this is why a convex lens is used, to push the focal point back so it will hit the retina.
A concave lens would do the opposite for hyperopia (the focal point appears behind the retina), it will adjust the focal point to lie more anteriorly and land on the retina.
Diverging Lens are use (reading glasses) to help correct the problem of myopia helping fix the focus which causes items far away to seem fuzy and blurry.
It would be concave lens. This is because it diverges the light before it enters the eye.
A convex lens is curved outward on both sides. Also, a convex lens, is used to enlarge objects.
