How does night blindness affect your body?

Night blindness, also known as nyctalopia, is a condition that makes it difficult to see in low light conditions. It is caused by a deficiency of vitamin A, which is essential for the production of rhodopsin, a pigment that is necessary for night vision.

Night blindness can affect people of all ages, but it is most common in children and older adults. It can also be caused by certain medical conditions, such as liver disease, diabetes, and retinitis pigmentosa.

Symptoms of night blindness include:

* Difficulty seeing in low light conditions

* Bumping into objects in dimly lit areas

* Needing to squint or use bright lights to see

* Increased glare from headlights and other bright lights

* Difficulty driving at night

Night blindness can be diagnosed with a simple eye exam. Treatment typically involves taking vitamin A supplements or eating foods that are rich in vitamin A, such as carrots, sweet potatoes, and spinach.

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 other potential causes.
