Adults who wear glasses should generally have their eyes checked at least once every two years according to the American Academy of Ophthalmology, with the possibility of more frequent exams depending on individual circumstances such as age, eye health, and risk factors.
More frequent eye exams (annually or as advised) are recommended if you have conditions such as diabetes, family history of eye diseases, experience vision changes or symptoms like blurry vision or eye pain, or are over 40 years old due to increased risk of age-related eye problems. Children who wear glasses usually need annual eye exams because their eyes are still developing.
Regular exams ensure your glasses prescription is current, maintain eye health by detecting conditions like glaucoma or cataracts early, and can even reveal other health issues such as high blood pressure or diabetes.
