Age-related eye changes can make it harder to see at night. These changes include the loss of light-sensitive eye cells called rods, which are essential for seeing at night; smaller pupils that let less light into the eyes; slowed reactions to changes in light, such as when walking into a dark room from a bright room; clouding of the lenses inside the eyes, which may cause glare around streetlights or headlights; and worsening vision that makes it harder to discern fine detail.

Vision loss has many risk factors. Some risk factors are well known, such as diabetes, high blood pressure, and older age. Other risk factors for vision loss are not as well known, such as inactivity, psoriasis, shingles, and smoking. People who have these risk factors might need eye exams more often than the standard recommendations for healthy adults (a comprehensive eye exam every two years from ages 40 to 65, and every year or two after age 65).

Night blindness makes it hard to see in dim or dark settings, which can affect safety at home and make driving dangerous after dark. While the cause varies, there are steps people can take to address these problems.
