Poor night vision often creeps up as we get older. You might feel fine one year, then suddenly notice increased glare from oncoming headlights or difficulty seeing clearly in low-light environments. For many people, these changes are subtle at first but become more noticeable over time.

Why Adults Should Take Night Vision Problems Seriously

Glare and difficulty seeing at night can certainly be frustrating, and in some cases, they’re part of the natural aging process. However, worsening night vision can also be an early sign of an underlying eye condition. Because nighttime driving and low-light navigation rely heavily on contrast and light sensitivity, even mild changes in vision can affect safety and quality of life.

Common Causes of Poor Night Vision

Several age-related eye conditions can contribute to night vision problems.

Cataracts

By age 80, about half of adults either have cataracts or have undergone surgery to remove them. Cataracts cloud the normally clear lens of the eye, which interferes with how light is focused, making it harder to see clearly at night. In addition to glare and halos, cataracts may also cause blurry or hazy vision and a loss of color clarity. Some people even notice difficulty reading during the day.

Diabetic Retinopathy

Diabetic retinopathy affects millions of people in the U.S., with older adults making up a significant portion of those impacted. Vision changes tend to worsen gradually, often beginning with blurred vision, empty or dark areas in the field of view, or an increase in floaters. Proper diabetes management and yearly dilated eye exams are essential for reducing the risk of vision loss.

Dry Eye

Dry eye can occur at any age, but it becomes more common as we get older. When the eye’s surface isn’t properly lubricated, vision may appear blurry, and glare, halos, or streaks around lights can become more noticeable at night. Artificial tears, specialized eyewear, and small changes in daily habits, like blinking more often, can help relieve symptoms.

Glaucoma

Glaucoma affects tens of millions of people worldwide and can interfere with night vision by reducing contrast sensitivity and increasing glare and light sensitivity. Some medications used to treat glaucoma may also constrict the pupils, which can further worsen glare in low-light settings.

Macular Degeneration

Age-related macular degeneration (AMD) commonly causes people to limit nighttime driving. Symptoms may include blurry central vision, glare sensitivity, reduced contrast sensitivity, and difficulty reading road signs, especially at night.

Changes in Pupil Size

As part of the aging process, pupils may not dilate as efficiently in the dark. While dilation allows more light into the eye, it can also increase glare from headlights and streetlights, making nighttime vision more challenging.

Night vision problems can affect independence and safety, especially when driving. While these changes are common with age, they can also signal an underlying eye condition that may benefit from treatment.

Annual comprehensive eye exams allow for early detection of vision problems and can help preserve both your eyesight and your quality of life. To schedule your exam, contact North Florida Cataract Specialists and Vision Care today at 352-373-4300.
