1. Myopia is corrected by concave but hypermetropia is by convex

2. Myopia far point is decreased while in hypermetropia near point is decreased

3. Myopia eye lens is thick while in hypermetropia eye lens is thin

Hypermetropia is corrected by convex lens.

Myopia:

Myopia far point is decreased.

Hypermetropia:
