Night blindness is a symptom that makes it hard for you to see in dark places or for your eyes to adjust to sudden changes between bright light and darkness. Many conditions can cause it, and they can involve many parts of your eyes. Fortunately, most of the causes are treatable.

What are the most common causes of night blindness?
Conditions that can cause night blindness usually fall into two broad categories: Not enough light getting to your retinas or your retinas not working properly. Conditions that involve issues with light traveling through your eyes include: Cataracts. Glaucoma. Laser vision correction surgery (like LASIK or similar procedures). Retina-related causes of night blindness include: Rare, genetic retinal diseases like cone-rod dystrophy, retinitis pigmentosa (also called rod-cone dystrophy, similar to but not the same as cone-rod dystrophy) or congenital stationary night blindness (CSNB). Vitamin A deficiency (especially in people who have trouble absorbing vitamin A after weight loss surgeries like gastric bypass surgery).
How is night blindness treated?
Treating nyctalopia involves treating the cause. Some conditions are treatable or even curable, like cataracts or vitamin A deficiency. A few of the conditions that cause night blindness, especially genetic diseases, aren’t treatable. For these conditions, the only option is to try to limit the effects of night blindness or other symptoms. Because so many different issues can cause or contribute to night blindness, the treatments vary widely. Your eye care specialist is the best person to tell you more about what caused it and the possible treatment approaches.
Can night blindness be prevented?
Some causes of nyctalopia are preventable. An example is taking vitamin A supplements after gastric bypass surgery to avoid a vitamin A deficiency. Care at Cleveland Clinic Eye Care Find a Doctor and Specialists Make an Appointment
When should this symptom be treated by a doctor or healthcare provider?
Night blindness isn’t something you can self-diagnose or self-treat. If you notice it happening, it’s always a reason to see an eye care specialist. While most causes aren’t dangerous, they can still disrupt your eyesight, and early diagnosis and treatment may help avoid bigger issues in the future. And if you start noticing you’re having trouble seeing in dark settings, you should avoid driving or other potentially dangerous activities until you see an eye care specialist. Until they tell you it’s safe to resume those activities, it’s best not to risk the health and safety of yourself or others. Advertisement
Is night blindness a disability?
Yes, but the laws and regulations where you live are also a factor. Some places have laws and regulations that recognize night blindness as a vision impairment. Others may not. If you aren’t sure, an eye care specialist can give you a formal diagnosis and offer guidance on what you’ll need to seek disability protections, or refer you to other experts who can help. A note from Cleveland Clinic Being afraid of the dark is something that happens to adults, too —especially when they can’t see well in dim or dark settings. Nyctalopia can happen for many reasons, most of which are treatable. If you start noticing you’re having trouble seeing at night or in dark places, talk to an eye care specialist. They can determine what’s causing your issues and help find ways to treat the cause or work around its effects. Most importantly, they can help you find ways to work around, or not to fear, what you can’t see. Medically Reviewed Last reviewed by a Cleveland Clinic medical professional on 12/19/2023.
