12 Strange Symptoms That Might Mean You Have a Vitamin Deficiency
5. Poor Night Vision: The Vitamin A Deficiency Indicator

Poor night vision, or difficulty seeing in low-light conditions, can be a sign of vitamin A deficiency. Vitamin A is essential for maintaining healthy vision, particularly in dim lighting. A deficiency in vitamin A can lead to night blindness, a condition where individuals struggle to see in low-light environments. Vitamin A is a key component of rhodopsin, a protein in the eyes that enables vision in low-light conditions. When vitamin A levels are insufficient, the production of rhodopsin is impaired, leading to poor night vision. In severe cases, vitamin A deficiency can also result in xerophthalmia, a condition characterized by dryness of the eyes and potential vision loss. To improve night vision and prevent vitamin A deficiency, it is important to consume a diet rich in vitamin A. Foods high in vitamin A include liver, fish, dairy products, and orange and yellow fruits and vegetables such as carrots and sweet potatoes. In some cases, supplementation may be necessary to restore optimal vitamin A levels and improve vision. By addressing this deficiency, individuals can enhance their night vision and reduce the risk of more severe eye conditions.
