Can your eyesight gradually change so that you no longer need glasses?

Yes.: As you age, there are natural changes that occur in one's eye that can result in one no longer needing glasses because their refractive correction has changed. An example would be a far sighted (hyperopic) patient requiring less of a hyperopic correction as a result of cataract development as one ages. This results in the lens of the eye becoming thicker resulting in a more myopic correction.
