Changes with aging include Decreased retinal illuminance (amount of light reaching the retina), visual acuity, contrast sensitivity, and peripheral vision Presbyopia (decreased ability to accommodate), which impairs depth perception Decreased ability to adapt to changes in light and heightened sensitivity to glare, which impair night driving Ocular diseases common with aging include Age-related macular degeneration Cataracts Glaucoma Diabetic retinopathy In many states, central visual acuity and peripheral vision are routinely tested by the Department of Motor Vehicles when a license is renewed.
