@ashby1947, and all...Hello, Ashby. I use the Dry Aid for extremely dry eyes. They're made in Japan, with Povidone and Propylene Glycol. I don't know about the preservatives, the information is on the box which I don't have. I'm sensitive to preservatives and don't ever use anything with them, and don't have any issue with these drops. I must have checked the ingredients prior to purchase, but you're on your own there.

I have double vision with lots of other dry eye problems mixed together. These are the only drops to date that help all my issues. I use them every morning and I can see clearly! No double vision for some time. I consider that miraculous for me. No itching, very cooling, no redness, no blurring, it's a real gift. They don't solve the problem. The problems return during the day, so I reuse the drops as often as I need and they help. By day's end, I don't see as well, but I'm not fussing about that. What a joy to have improved sight for the first time in years!

I hope you find good results if you try them, Ashby. They aren't cheap but they work for me. I'm grateful to have found them, on a U-Tube make-up tutorial for crying out loud! From a New York make-up stylist who focuses on older women, 40-100 years, improving our make-up as we age and many of us enjoy our gray hair. I love it! Fierce aging she calls it. I agree! And, I do look better using some of her tips. She models and has used these drops to aid her eyes for early morning modeling calls, and such. When I researched them, I found the dry eye aid and fell in love...

Hope they help you!
Blessings, Elizabeth
