These drops work very well for some people and not for others. I finally found an ophthalmologist who specializes in treating chronic dry eye and she explained why. MGD stands for Meibomian Gland Dysfunction which occurs when the glands that provide the lipid (oily) portion of your tears stop functioning correctly. I have this problem, so these drops work very well for me. They are not so good for people who have dysfunction in the lacrimal glands which provide the watery portion of your tears. Those people benefit more from artificial tears. My previous ophthalmologist had me using artificial tears every two hours. Even that was not enough and my eyes bothered me all of the time. Now, I use Retaine MGD three to four times a day and am quite comfortable. What a relief! Note, I've now also had the Lipoflow procedure done and have started taking Retaine OM3 supplements to help my Meibomian Glands function again. I'm finding all three worthwhile, but the MGD drops were my first step towards relief. Read more

I live in the desert southwest and boy does this stuff come in handy! More often than not our humidity is down in the single digits, with lots of dust in the air. So, when these drops are applied it always provides wonderful relief for hours, even most of the day. Also, at night I have a problem where my eyelids don't shut tight enough and the eyeball gets really dry. So I keep these drops handy and they really really help! What impresses me is the duration of the relief, that you don't have to put drops in every 30 minutes for help. I highly recommend this product, especially for you dry-eye sufferers. Read more

I use these drops at nighttime and they mostly get me through to morning without feeling that I need to put more in when I get up. They are a whole lot cheaper than using restasis! Read more

These are ok. They take some getting used to. It's a bit difficult to squeeze the drops out sometimes so they sometimes miss the mark but the solution when I finally get it in my eye is very, very gentle. I like this over the other drops I've used. My doctor prescribed these for my dry eye problem and I have not had the stinging problem as long as I use them every day. Read more

The best treatment for dry eye. My eyes form very few tears, and this product, although it is primarily mineral oil, is very soothing and can be used several times a day, if necessary. Most other artificial tears are water based, and they can eventually be irritating if used several times a day. Not this product. Very good, yet hard to find in the stores. Read more

I read about Retaine drops when I experienced swollen eyelids and worse-than-usual dry eyes for months following cataract surgery. I showed an article on Blepharitis to my eye doctor, who agreed I should use Retaine in conjunction with several other treatments. The drops are soothing, and immediately helped my pain, so despite the cost, I'll use them indefinitely in treating my dry eyes. My eyelids are also much better. Read more

My doctor recommended this because he said I didn't have oil glands in my eyes, but my eyes actually feel better when using Tears Naturale daily. I still use Retaine once in awhile, but my eyes feel better if I don't use it very often. However, my mother swears to Retaine's effectiveness. So my recommendation is to try it, but don't buy tons of it in case you are someone like me. Read more
