Slowly: In adults, eyeglass prescriptions change at the rate such that about every 2-3 years new glasses are needed.

Depends: Normally, the glasses prescription in an adult changes slowly. There are some conditions like elevated or reduced blood sugar levels that can change your prescription rapidly. Also, there are some pathologies that cause elevation or recession of the retina and change your prescription. If you feel your prescription may have changed, see your specialist eye md (ophthalmologist).
