BLINKPreservative-Free Sterile Lubricating Eye Drops for Mild to Moderate Dry Eye Symptom Relief, 25 Count 0.01 fl oz Vials

I like the Blink brand... they feel good in my eyes. My Dr told me to get preservative free drops prior to cataract surgery. I bought these. They work great.

I've wasted so much money on eye drops and finally found these. They come in little single use droppers and make my eyes moist and not blurry. I have them in my home,my purse and my car. I feel like they are much more sanitary because they are sealed and you only have to open once. They keep my eyes from getting dry for hours.

Blink works well for my uncomfortable, itchy dry eyes. My eyes get this way when the air is dry, which it has been here in the Northeast this fall and winter.I am glad I ordered it and it provides me quite a bit of relief.All you do is snap off the top and apply it to one or both of your eyes! It’s particularly useful at night when you are trying to get ready to go to sleep!

Appears to be a good product and it should work well.

My eyes tend to get dry. These have been perfect because they are preservative free so I can put them in a heck of a lot more often than other lubricating drops. My vision is clear and it tends to work for about a half an hour to an hour before I have to reapply.

I really love this product. It helps my dry eye.

Immediate relief for dry eyes! Highly recommend

They are designed to be disposable after a single use, and you will be hard pressed to get multiple uses that maintain an ideal chemical reaction. As such, these economic ratings are not done by milliliters, but by price per whole vial. So the vials with more fluid in them are not necessarily a better deal. That said, some vials may be designed with an unsatisfactory amount of fluid per vial for even a single use. You decide.GRAND TOTAL RECOMMENDATIONSAllergan Refresh: Recommended for evening/nighttime useBausch & Lomb: HIGHLY RECOMMENDEDBlink Tears: Recommended with reservationsSimilasan: Not RecommendedSystane Ultra: HIGHLY RECOMMENDEDTears Naturale: Not RecommendedTheratears: Not RecommendedEveryone's eye chemistry is different, and different products will affect each person uniquely. So keep your mind open and be willing to try many things. Consider also: humidifiers, night gels, eyelid cleansers, microwaveable hot pads, sunglasses, and anything else out there.
