Vitamin A: The blue Mountains Eye study found that elevated beta carotene intake was assoicated with an increased risk of macular degeneration.

Vitamin B2 (riboflavin): Deficiency can cause red eye, photosensitivty, and dry eye.

Vitamin B7 (biotin): deficiency can lead to dry scalp, dandruff, or hair loss.

Vitamin B9 (folate): unmetabolized folic acid can accelerate cardiovascular and ophthalmic vascular disease.
