Does wearing eyeglasses cause your vision to deteriorate? No — wearing glasses does not cause your vision to deteriorate. This is one of the most persistent myths in eye care. Especially from new eyeglasses wearers.
Glasses are a tool. When your glasses are on, you see well. When you remove your prescribe glasses, you see blurry. Wearing eyeglasses does not interact with your eye's biology, doesn't weaken your eye muscles, and doesn't your prescription to shift.
Prescriptions change because of biology — not lenses. In children and teenagers, the eye grows physically longer, which increases nearsightedness regardless of whether glasses are worn. In adults over 40, the crystalline lens inside the eye gradually loses flexibility, causing presbyopia (the inability to focus on a near target). Neither process is influenced by wearing corrective lenses.
The reason people suspect glasses are the culprit is the contrast effect — your brain get used to sharp vision, so removing your glasses makes blur feel worse than before. The quality of your blur didn't change; your perception of it did.
So, wear your glasses confidently and see the world . . . clearly.
