Vitamins A, riboflavin (B2), and ascorbic acid (C): Their description, deficiency, and roel in eye health and vision

1 May 1979


Vitamin A nutriture does not pose a serious threat in America today; supplementation, when suggested in the absence of clinical signs of deficiency and abnormal metabolism, should be in the form of the provitamin, B-carotene, In the absence of anterior segment pathology there is no evidence that riboflavin (B2) therapy will alleviate photophobia or any other visual symptom, Vitamin C supplementation should emphasize the avoidance of both hyper and hypo-vitaminosis C, accomplished by the daily consumption of 100-150 mg of vitamin C, which will result in tissue saturation, Further research is needed to clarify any relation between axial myopia and vitamin C deficiency or disordered metabolism.
