Night Vision Problems: Halos, Blurred Vision, and Night Blindness

How Are Night Vision Problems Diagnosed?

Blurry vision or poor night vision are good reasons to schedule an appointment with an eye doctor.

A simple exam and conversation at an eye doctor's office will uncover virtually any serious cause of night blindness. The doctor will dilate your eyes with drops and examine your eyes with a slit-lamp, an upright microscope with a bright light mounted on it.

How Is Night Blindness Treated?

A common cause of poor night vision -- cataracts -- is also one of the most treatable. Cataract surgery replaces the clouded natural lens with a clear manufactured lens known as an intraocular lens. Vision is improved, often dramatically, although many people will still need to wear glasses.

Diabetic retinopathy can be prevented by tightly controlling blood sugar levels with medicines and diet. One treatment for advanced diabetic retinopathy uses a laser to destroy tiny budding blood vessels that threaten vision. Called panretinal photocoagulation, this laser procedure preserves vision overall but may reduce night vision afterwards. 

Although vitamin A and zinc deficiency aren't common causes of night blindness, it's worthwhile to eat a diet rich in these nutrients if you're having night vision problems.
