Which Vitamin Causes Night Blindness?

Night blindness, also known as nyctalopia, is primarily associated with a deficiency in vitamin A. Vitamin A is a crucial nutrient for maintaining good vision, especially in low-light conditions. It plays a vital role in the functioning of the retina, which is the part of the eye responsible for capturing light and sending visual signals to the brain.

When someone lacks sufficient vitamin A, their ability to see in dim light or darkness is impaired, leading to night blindness. This condition can be particularly problematic when navigating in poorly lit environments or during nighttime.

It’s important to ensure an adequate intake of vitamin A through a balanced diet that includes foods such as carrots, sweet potatoes, spinach, kale, broccoli, and liver, as well as fortified dairy products and certain fish. Severe vitamin A deficiency can lead to more severe eye problems and even blindness, so addressing any deficiency is essential for maintaining good eye health. If you suspect you have night blindness or other vision issues, it’s always best to consult with an eye care professional for proper evaluation and guidance.
