December 16, 2020Can you comment on supplements like Preservision? Does that help with dry eyes?
There is no evidence that PreserVision can improve dry eye. Although another supplement similar to one of the PreserVision formulations used in clinical research (this formulation is not available in the U.S.) did show benefit for dry eye symptoms, the primary ingredient in this formulation was omega-3 fatty acids. Omega-3 fatty acids alone can improve dry eye (as noted in our answer above), but there is no evidence that added vitamin/antioxidant ingredients - such as those in PreserVision - provide additional benefit for dry eye.
