Do Glasses Ruin Your Eyesight?

The video debunks the myth that wearing eyeglasses ruins eyesight, explaining that vision problems are due to the shape of the eyeball, not weak eye muscles. Glasses help focus light onto the retina, reducing eye strain. Historically, optometrists under-prescribed glasses for children, believing it would prevent worsening myopia, but studies showed this was ineffective. Modern understanding is that glasses do not harm vision and may prevent deterioration. As people age, stronger prescriptions may be needed due to stiffer lenses, not because of glasses.
