Eyeglasses work using the principle of refraction. Refraction means you are bending light. To focus light into a point means to converge it, while scattering light means to diverge it. Farsightedness and presbyopia require converging lenses to bend the light sooner and shorten the focal distance, while nearsightedness requires diverging lenses to make the light converge later and lengthen the focal distance. So eyeglasses move the point where the light rays come together so the light can focus directly on the retina. The retina is the sensitive part of the eye that perceives light and sends it to the brain.
