What does Night Blindness do to people?

Night blindness (also called nyctalopia) is a condition that makes it difficult to see in low light conditions, such as at night or in dimly lit rooms.

It is caused by a deficiency of vitamin A, which is essential for the production of rhodopsin, a pigment that is necessary for vision in low light conditions.

Night blindness is most common in people who are malnourished or who have certain medical conditions, such as liver disease, diabetes, or cystic fibrosis.

Symptoms of night blindness include:

* Difficulty seeing in low light conditions

* Needing to use bright lights to see at night

* Glare from headlights or other bright lights

* Difficulty judging distances in low light conditions

Night blindness can be treated by increasing your intake of vitamin A. Good sources of vitamin A include:

* Liver

* Sweet potatoes

* Carrots

* Spinach

* Kale

* Collard greens

* Apricots

* Mangoes

* Cantaloupe

You can also take vitamin A supplements to increase your intake. However, it is important to talk to your doctor before taking any supplements, as too much vitamin A can be toxic.

Night blindness is usually a temporary condition that can be easily treated by increasing your intake of vitamin A. However, in some cases, night blindness may be a sign of a more serious underlying medical condition. If you are experiencing night blindness, it is important to see your doctor to rule out any underlying medical conditions.
