My husband is 55 years old and only needs glasses to read. How often should he have an eye exam?

From the American Academy of Ophthalmology policy statement on frequency of examination: "For young individuals at higher risk for certain diseases, such as African-Americans who are at higher risk for glaucoma, comprehensive eye examinations should be considered every 2 to 4 years for those under age 40, every 1 to 3 years for those aged 40 to 54, and every 1 to 2 years for those aged 55 to 64, even in the absence of visual or ocular symptoms. Adults with no signs or risk factors for eye disease should receive a baseline comprehensive eye evaluation at age 40. For asymptomatic individuals or individuals without risk factors who are 40 to 54 years old and who have had a comprehensive eye examination, the recommended interval for evaluations is 2 to 4 years. For individuals aged 55 to 64 years old, the recommended interval for evaluations is 1 to 3 years. For individuals 65 years old or older, the American Academy of Ophthalmology recommends an examination every 1 to 2 years, even in the absence of symptoms."
