Why do my glasses magnify my eyes?
In contrast, convex lenses are used for hyperopic (farsighted) prescriptions, and if the positive power (magnifying) of the lens isn’t best for how high the prescription is, this corrective lens causes big eyes behind your glasses! The higher the power, the more exaggerated the magnifying or minifying effect will be.
