These tiny doses of eye lubricant remove most of my concerns about my eyes being exposed to potential contaminants from the exposed tip of a dropper bottle inadvertently contacting an unsanitary surface or if someone asks to borrow some. Touching the tip to the eye or brushing it with a finger when opening or closing the bottle lingers in my mind as a what-if. With each single-use vial dispensing 6-8 drops consistently they make wearing extended wear contacts more comfortable and less concerning regarding potential contamination risk.

It's a retail product sold at Costco. Good expiry date. Box with viles was a little misshaped, yet its content seems to be ok. Either rigid mailer should be used (the actual was of bubble plastic), or the content itself should have additional rigid shell of some kind.

Preservative -Free Refresh Plus Lubricant Eye Drops has made a noticeable difference with my dry eyes. Through the years, I’ve tried a few other brands, but Preservative-Free Refresh Plus seems to bring the most improvements to the level of dryness and tear production. The price per vial is very economical in the 100 pack as well. Great product with a great price!

These are wonderful and convenient. Just toss a few in a pocket or purse and go. No worries about contamination or chemicals. I have used them daily for several years for my extremely dry eye caused by Shingles. Also, you cannot beat the price at Sams.

I love that these are individual vials with enough drops to refresh your eyes. I feel my eyes are safe from unwanted germs that you might get from a bottle of drops that you open, close and reopen many times. May be more expensive, but not much and so much safer.

I was pleased to find the 100 vial packages and at a decent price. Arrived much more quickly than I thought due to world circumstances... I like that Walmart is working with Costco??? to get things in consumer hands. I say this because I ordered through Walmart.com but the product came in a Costco box.

I do like the fact that I use these once and toss them, but they are difficult to use. The large bottles were easier to get drops out of, and these have just enough for 2 drops in each eye. If you miss your eye you have to use another vial. My ophthalmologist likes the preservative free vials better, too.

Great bulk pricing. There are few drops inside compared to another brand I use, and the other brand I use also provides longer lubrication. But since I need to use drops frequently, this is good for a lower bulk price. I also have a harder time aiming these compared to my other drops, as if the end doesn't aim them straight.

These eye drops are recommened by my ophthalmologist because the are one dose in sterile packaging. I like them because you cam slip them in your purse or pocket and have them available when you need them. The eyedrops really help with dry and tired eyes.

These are really good eye drops in their own individual vials. I get 2 uses out of each vial. Also good for traveling as they are lightweight and easy to carry. And when you came home they are gone, so less to carry home. They are also preservative free.
