●Vitamin A is found in many foods, including leafy green vegetables, orange vegetables (carrots, sweet potatoes, pumpkin), eggs, and cantaloupes. A lack of access to a balanced diet with enough vitamin A can lead to vitamin A deficiency.

●Vitamin A plays an important role in your vision. To see the full spectrum of light, your eye needs to produce certain pigments for the photoreceptor cells in your retina to work properly. Vitamin A deficiency stops the production of these pigments, leading to night blindness.
