Night Vision Help Hendersonville, TN

Vision problems are frustrating, no matter what time of day it is. Yet if you have trouble seeing at night, those mildly annoying vision problems quickly become frightening. You need to know why your vision could be worse at night and what to do to solve the problem. The team at Judd Family Eyecare is eager to help you cope effectively with night vision issues.


What is Night Blindness?

It’s important to distinguish between overall poor vision and actual night blindness. People with night blindness can usually see normally in adequate light. At night though, they experience moderate-to-severe visual changes. Night blindness is not true blindness, but it can result in serious injuries and disconcerting symptoms of vertigo or a loss of your sense of location.

Whether you have night blindness also depends on how long you are unable to see in the dark. Most people can see adequately in the dark in about 20 minutes. Keep a vision diary during the day. If you notice that you can’t see in the dark within that time, make a note and discuss the frequency with your eye care professional.


What Causes Night Blindness?

In dim light or darkness, your pupils automatically grow larger, or dilate, to adjust. However, this dilation may cause you to lose visual focus. It may be more difficult to tell how near or far away objects are or change your focus between objects. If it takes too long for your focus to shift, you could be injured. For example, people with night blindness often should not drive after dark, because they can’t react quickly enough when headlights or traffic lights enter their visual fields.

Additionally, night blindness can worsen if your eyes constantly need to focus between light and dark. For instance, you may be susceptible to night blindness if you work at a nighttime job or if you have driven at night for several years. If you often get up at night to check email or your phone or if you suffer from insomnia, you may be at risk for night blindness, too.


Coping With Night Blindness

Your eye doctor will recommend several steps to help you cope. These may include a Vitamin A supplement or a diet rich in foods like mangoes, spinach, and carrots, which help vision. He or she may also advise you not to drive at night and to wear protective eyeglasses. If you must drive at night, keep your car windows and windshield clean, and do not look directly into oncoming headlights.
