In general, discuss with your primary care physician when you need to see an ophthalmologist. Go over your family’s eye health history to determine if you’re at higher risk for certain diseases.
If you wear glasses, see your eye doctor annually to keep your prescription up to date and to screen for issues like retinal detachment.
After age 40, you should see an eye doctor once every two years. In addition to screening for asymptomatic issues like glaucoma, ophthalmologists often are the first to detect conditions such as diabetes and high blood pressure.
If you experience vision changes at any time, such as blurriness or dimness, make an appointment with your eye doctor right away.
