How often do I need to have my eyes examined? Everybody should have a regular checkup. Children and pre-teens should be screened by a     pediatric ophthalmologist. Teenagers should have an examination every 4-6 years Ages 20-49 should be checked at least once every 3-5 years Ages over 49, should be checked more frequently, every     1-3 years. Examination may be performed more frequently for specific purposes (diabetes, macular degeneration, etc), eye glasses prescription, contact lens fittings, or patient preference.
