BLINKTears Lubricating Eye Drops Preservitive Free, Moisturizing & Soothing for Mild to Moderate Dry Eyes, with Hyaluronate, Reduces Discomfort, Long-Lasting Hydration, 0.01 Vials (25 Count)

This product gets the job done. I wear contacts most often and my eyes tend to get dry. Blink adds enough moisture to help ease the dry sandpaper feeling that sometimes happens with dry eye. And it doesn't burn upon application like some other eye products do. The relief doesn't last for hours on end, but it definitely helps for a short while. No build up or weird feeling in the eyes. Easy to open and close the bottle, no leakage while carrying it around all day. Solid choice for temporary dry eye relief.

Really does refresh my eyes! Individual applicators are easy to use without worrying about preservatives.

packaging is wonderful, no extra drops flooding your eyes. this packaging prevents waste of excess drops! love this product and buy regularly.

Okay, my eyes have been feeling like two little deserts lately, thanks to screen time and maybe just getting older (ugh). Picked up these Blink Boost Preservative-Free drops hoping for some relief, and yeah, they definitely deliver on that front.Putting a drop in feels instantly soothing – like giving your eyeballs a tiny, much-needed drink. Big plus that they're preservative-free, 'cause I tend to use drops throughout the day, and who needs extra chemicals, right? They don't sting or blur my vision much either, which is great.So, the 4 stars instead of 5? It's the bottle, man. This fancy preservative-free dispenser has a mind of its own sometimes. Getting that perfect single drop requires a certain finesse, a specific angle, maybe a whispered prayer? Sometimes I nail it, sometimes I get nothing, sometimes I accidentally give myself a double dose. It's not impossible, just a bit… quirky. Way more fiddly than a standard eye drop bottle.But hey, the drops inside are great. They work, they soothe, and they don't have those preservatives. 4 stars seems fair. If you need good, frequent relief, give 'em a try – just be ready for a little 'getting to know you' period with the bottle.

The drops do a good job, may need to use more than two or three times a day

I recently got Lasik surgery and they suggested these ones. I love the way they feel when I put them in my eyes and I use them throughout the day.

As I age my eyes were getting drier and drier. My optometrist recommended this as really the last step before having to look at prescription drops. These are great, and get the job done.

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.
