I was just wondering if anyone has tried castor oil in their eye for added moisture?
I've tried drops with castor oil in the past, emulsions like Restasis and Refresh Endura, but all they did was irritate. I'd guess b/c of the glycerin and emulsifiers.
Theoretically, like jojoba oil on a wet face, using castor oil after wetting the eye with an eyedrop should mimic the tearfilm that's naturally created by the lachrymal and meibomian glands. The eye surface being slick ,however, doesn't absorb oil like the skin. I normally use jojoba oil to remove eye makeup, occasionally adding safflower, and if too much gets in my eyes they're bothered. So I don't imagine castor oil would be any different. I just have to believe there is a natural way to make our dry eyes feel more normal. Omega 3's and flax oil do wonders internally, but topically eyedrops are not enough on their own.
