Night Vision Problems: Symptoms, Causes & Correction

Turning the Spotlight on Poor Night Vision

Poor night vision or night blindness (and if you want to impress your friends with the medical term – Nyctalopia) refers to a more-than-normal difficulty seeing in dim light or at night. This difficulty with seeing in the dark also tends to be more noticeable when you move from a brightly lit area into a barely lit one, and vice versa. Most people report first noticing the problem when driving at night.

How Is It Diagnosed?

If you notice such symptoms and think you may have poor night vision, consult your ophthalmologist immediately. Your usual eye examination won’t reveal poor night vision, so you may need to request to be tested.

Testing for night blindness is a simple process in which your doctor will use eye drops to cause dilation and then examine your eyes with a Slit Lamp (a microscope with a bright light on it). After this, there is a series of tests that detects key identifiers of night blindness.

Poor Night Vision And Age

Poor night vision is seen as an “old age” problem. While it tends to affect people as they age, it can affect anyone at any age. However, most sufferers notice a significant loss of vision at night after their 40th year.

And things can change relatively quickly, for example, an average 50 year old may need twice as much light in order to see like an average 30 year old. In addition, poor night vision is sometimes a symptom of an underlying condition, so it’s possible that it can happen to anyone, of any age, even children.
