Eyeglasses work by bending light rays in the eyes of those who can't see well so that they reach the back of the eye properly (called the retina). When the light rays reach the appropriate part of your eyes you see better.
Eyeglasses with corrective lenses use refraction to focus light correctly onto the retina, allowing for clearer vision. The lenses bend and redirect light to compensate for any refractive errors in the eye, such as nearsightedness or farsightedness. Absorbing or reflecting light would not correct vision problems in the same way that refraction does.
be prescribed by an optometrist or an ophthalmologist. The prescription takes into account the individual's specific vision needs, such as nearsightedness or farsightedness. Wearing the correct prescription lenses helps to correct the refractive errors in the person's eyes and improves their ability to read and focus on objects at close distances.
