Because the ability to drive preserves seniors’ independence, drivers over age 65 should do everything they can to preserve their driving skills, including having their vision checked. The American Academy of Ophthalmology recommends that those aged 65 years and older have their eyes examined once every one to two years even if they experience no issues. An exam can determine if eyeglass prescriptions need to be updated and whether there are any signs of disease that could compromise vision and hamper driving ability. For instance, cataracts can make objects appear blurry and/or make vision more sensitive to the glare of oncoming headlights, and glaucoma decreases peripheral vision, making it harder to see objects away from the direct line of sight.
P.S. “Contrast sensitivity” is particularly important for discerning objects at dawn and at dusk and should be checked in a senior’s eye exam.
