People get vitamin A deficiency when they do not eat a balanced diet with enough vitamin A. If you have vitamin A deficiency, you may have trouble seeing at night (night blindness). If untreated, it can lead to corneal ulcers and permanent blindness. Vitamin A deficiency is treated with vitamin A supplements.
If you have any questions about your eyes or your vision, speak with your ophthalmologist. He or she is committed to protecting your sight.
