Vitamin D and Dry Eye

In the December 2024 edition of the Cornea Journal, Dr. Antonia Vieira and colleagues published a study about dry eye and vitamin D.

They reference the fact that there is an association between Vitamin D deficiency and dry eye disease. There is some evidence that replenishing vitamin D in patients with deficiency can improve the ocular surface.

So, if your eyes are dry, perhaps you should test your vitamin D level and take vitamin D supplements.
