Does wearing glasses help eyesight in the long run?

To clarify: if someone had prescription glasses, would it be more beneficial for long-term eyesight health to constantly wear the glasses or keep them off until needed? 

Scenario: Clone A and Clone B, aged 18, both need prescription glasses to see clearly. Clone A wears glasses (constantly updates the prescription as needed) and Clone B does not wear glasses ever. By the age of 30, whose eyesight would be better without glasses?

Neither option has any effect. Glasses don't permanently affect eyesight in any way. Imperfect vision is due to light not properly meeting at the back of the eye, and either a convex or concave lens is used to bend the light to compensate for this. Natural vision will deteriorate over time regardless of this simply due to aging.
