Hypermetropia (Farsightedness) Explanation

Hypermetropia (farsightedness) occurs when:

• The eyeball is too short, or
• The cornea doesn't have enough curvature, or
• The lens isn't thick enough

This causes light rays to focus behind the retina when looking at near objects. A converging (convex) lens corrects this by bending light rays inward before they enter the eye.
