Re: Preservatives in drops and No Preservatives?
Apparently some preservatives can irritate your eyes if you use the drops too frequently. I've read that if you are using drops more than 5 or 6 times a day, the preservatives can cause irritation, so you should use preservative free drops. In the case of a gel for nighttime, I think if you got GenTeal gel you are OK. The GenTeal products have a disappearing preservative. Does it say that on the package? Something like "preservative free in the eye"? They have some special preservative that is supposed to dissolve on contact with the eye and therefore can't cause any irritation. Hope this helps!
