How do eyeglasses help you see clearly?

Answer: Bend light so it focuses on the retina

Make everything look bigger — Wrong. Glasses do not simply magnify everything. Their main job is to redirect light so the image focuses correctly in the eye.

Train your eyes to focus better — Wrong. Glasses do not train the eye. They optically correct refractive errors while you wear them.

Bend light so it focuses on the retina ✓ — Correct! Eyeglasses help by bending incoming light so the image lands on the retina. For myopia, concave lenses spread light; for hyperopia, convex lenses converge it. They compensate for focusing errors rather than simply magnifying the scene or training the eye.
