A member asked:

As far as getting sunlight to fight off sad, is it obtained through our eyes or skin? if eyes, would we benefit more by not wearing sunglasses?

A doctor has provided 1 answer

Through your eyes: Light boxes mean to replace natural sunlight exposure which when is missing or decreased it's felt to be contributing to SAD. What's damaging to the eyes are the UV rays, so chose a box that filters UV or it emits the minimum amount. Also it helps if you wear UV filtering eye glasses.
