Night blindness is an early symptom of vitamin A deficiency. This is because vitamin A is essential for the production of rhodopsin, a pigment in the retina that helps to detect light and enables night vision. Other symptoms of vitamin A deficiency may include dry skin, increased susceptibility to infections, and decreased immune function. However, headaches, hair loss, and swollen tongue are not typically associated with vitamin A deficiency.
