Hydration Boost, Preservative-Free Eye Drops for Dry Eyes, Instantly Moisturizes, Rehydrates, Contact Lens Friendly, Refresh & Relieve Eye Irritation, 30 Single-Use Vials (Pack of 1 )

My OD recommended these drops as a dry eye treatment for me. I cannot believe how great they work; very soothing drops that I love using. My only concern is the difficult/cumbersome dropper.

These are my go to eye drops as somebody with dry eye. My eyes used to get really dry and irritated when I would sleep to the point where I would sometimes wake up with abrasions on my eye that felt like stabs. I actually didn't think it was that bad and thought maybe it was just hurting from over dryness until optometrist confirmed these abrasions on the surface. I started using these before bed and again if I wake up to use the restroom in the middle of the night and it has significantly reduced the occurrences. Sometimes if it's really bad before going to bed I'll add some TheraTears to my eyes as well as it uses a different method for rehydration (not sure if it's good to mix but I haven't had any issues yet)

Literally, my favorite product ever! I have these all over the place. I use them 2 to 3 times a day. They are the most moisturizing eyedrop on the market. They are preservative free. They don’t cause rebound redness. They just keep your eyes moist and happy they’re great for contact lens wears, and just for general aging as we get older our eyes get dry and these are the perfect solution. The bottle is a little bit hard to squeeze which some people don’t like but that doesn’t really bother me. They don’t smell. They’re not sticky, but they are like thicker liquid going into your eye and they just feel so good.

I ordered these as a replacement for another preservative-free brand I was not satisfied with. I like these drops much more, they are not milky or make my vision temporarily blurry. They hydrate my eyes and feel fresh. The only reason I listed 4 stars instead of 5 is because I do not like how stiff and rigid the bottle is, it is hard to squeeze. The price was much better, comparable sizes and functionality, so I will most likely stick with these!

Biotrue eyedrops are the only eye drops I will purchase now. They are worth their price tag! If you suffer from dry eyes and the cheaper brands aren't providing you lasting relief, you have to give these a try. They are instantly soothing, like a hug for your eyes. And the effects last for quite a while before needing to reapply. With some of the competitor brands, I was applying constantly, every 5-10 minutes sometimes. Now I can squeeze in one drop per eye and I'm on my way for hours at a time. I spend my days staring at a computer screen so eye comfort is a must. I keep one on my nightstand, one in my home office and one in the office so I always have access when needed. The only con I can think of related to this product is when the bottle gets low, it gets a little more difficult to squeeze those last drops out, but not to the point where it is impossible. They will still come out, just with a little extra effort. It is a minor inconvenience and does not impact my love for this product. Highly recommended, very happy with my past (and continued) purchases!

After my go to brand became no longer available, I tried Biotrue on the advice of my eye doctor. They are soft and silky on the eyes and I hope they stay in business forever.

The eyedrops themselves, when you can get the solution into your eye, are great - however - if you're purchasing these eyedrops for someone with hand weakness, tremors, mobility issues in general - I (unfortunately) do not recommend buying this. :( 1. It's NOT like the standard Visine style delivery system where you barely squeeze the bottle and you've got drops everywhere (and one or two are guaranteed to hit the target). You must REALLY SQUEEZE HARD before even one drop comes out. 2. While you very firmly squeeze the bottle for quite a few seconds until a drop is released - if you have unsteady hands, and can't stand with head tilted back for more than 5-10 seconds, this will be difficult for you. 3. The cap does NOT "lock" on - you cannot tell if the cap is secure.. If you're going to put these drops in your purse, be sure to put them in a ziplock baggie to avoid the probability that the cap will come off if the bottle is loosely in a side pocket, etc. The drops are nice - they are soothing & seem to work ok. But the package design is so awful, I'm on amazon today trying to find another similar product with an easier-to-use dispensing bottle. Bummer. **Updated with a photo** Just used the drops to flush some dust out of my eye - and decided to include a photo to illustrate what the core of the problem could be. The tip is SO TINY and "barely there". With other eyedrops, you have something you can see that physically points to your eye (those of us who are blind without glasses on will "get" this lol). When you hold this away from your eye - I swear it's impossible to hit your eyeball with the drop, so you have to move it closer to your eyeball. And even then you can't get the drop to fall onto your eyeball. It needs to have an adequate-length tip that you can accurately aim at your eye to deliver the drop.

This is a combination review of a handful of preservative free eye drops. This is by no means extensive nor thorough. There are many others on the market that I have yet to try, but these were the ones I believed to be most relevant to my needs, which consist of relief after PRK surgery. Drops reviewed: Refresh Relieva for contacts Systane Gel Drops Systane Hydration PF Biotrue Systane Ultra PF Oasis Tears Plus I will cross post this on each of the other drops' pages. I will review the drops based on relief, perceived longevity, consistency, ease of use, and relevant features. At the time of this review, I am at exactly one month post surgery. I will be rating each of these drops 5 stars on their relevant pages because they all do exactly what they're designed to do and don't have any glaring issues that warrants fewer than 5 stars. The in-post reviews are relevant to comparing between these drops. Refresh Relieva (5 stars): These drops are fantastic. I find that I want to reach for these the most often when I'm looking for good eye lubrication. These drops spread over my eye very quickly without feeling like they stick to the edges of my eyes or eyelashes. Out of all the drops other than the gel, these drops feel like they last the longest in between drops. I use this the least often and find great relief for about half an hour before I want to use them again. These drops feel less slimy than the other drops except for Biotrue. Out of all of the other bottles, it's the most traditional dropper and easiest to use, but due to the design, it may be most susceptible to contaminants and early expiration. It's the only bottle that I'm able to fit my nanodropper onto and that will potentially mitigate the potential contamination and as a result, will prevent early expiration as well as extend the number of drops due to the smaller drops the nanodropper creates. Overall, these are my favorites drops. Systane Gel (3 stars): Out of all of the drops, I reach for these least often. I thought I might try them to see if they last longer and provide the longest lasting relief. If that's what you're looking for, these drops are great, except there are drawbacks that cause me to not use them. They're sticky. If I fall asleep with them in, my eyelids get a little glued together and I sometimes have to pick the gel out of my eyelashes and that can be very uncomfortable. They provide a great deal of relief for the longest period of time and that's the saving grace for these drops, but I'd rather not deal with the slime I get all over my face when I inevitably rub my eyes due to the uncomfortable residue that sits on the edges of my eyes and eyelashes. This dropper is very easy to use and on par with the Refresh dropper. I have no complaints about the amount it drops and the ease of use. Systane Hydration (5 stars): These drops are a very close second to Refresh overall. The relief is only noticeably less than Refresh because the Refresh feels so good. These are exactly what I would expect from a high quality drop and would not be disappointed if these were the only drops available to me. They last about 20-30 minutes and are easy to use. The consistency of these drops is pretty thin. They're only ever so slightly thicker than Biotrue, Ultra, and Refresh. The dropper produces a slight bit of waste if you don't stop squeezing at the right moment but is otherwise very easy to use. Overall, my second favorite drops to use. Biotrue (4 stars): The relief that these drops provide are comparable to Refresh except they don't last as long. I end up having to use these fairly frequently because they don't last very long. I've been using these drops just to get through the bottle. These drops just feel slightly inferior to Systane Hydration in almost every aspect. They go on very nicely and don't stick to my eyelashes or the edges of my eyes as much as Systane, but they don't last as long, provide comparable relief, and the bottle is far more difficult to use. The consistency is the thinnest out of all these drops. This bottle has a special technology that requires a great deal of force to squeeze out a drop. Despite that, the bottle creates a significant amount of waste no matter how you squeeze it, and you have to squeeze it pretty hard. This bottle is my least favorite to use even if the drops are pretty decent. Overall, these are my second to last choice only beating the gels. Systane Ultra PF (5 stars): I think that if I had gotten these in a bottle, they'd be my second favorite to use. They're my go-to for when I'm on the go and need portable drops. They provide a great deal of relief and give about 30 minutes of lubrication. I almost always grab a few of these if I'm going to be out of the house for an extended period of time. The consistency is thin and far less slimy than Hydration. I find that they coat my eye very well and don't stick to my eyelashes and the edges of my eyes. My only issue with these is that they create a significant amount of waste compared to the bottles. I also end up dropping them or losing them when they drop out of my pockets, but they serve a purpose. There's always some product that gets stuck in the twist off cap, so that's a problem too. They're great for transport though, and if I had a bottle, I'd probably prefer it over Hydration. Overall, I really like these drops but I feel bad about the waste. Oasis Tears Plus (3 stars): I feel like these drops are the standard for high quality drops. They provide a fair amount of relief, they last a fair amount of time (roughly 20 minutes), and they're the second most thick drops only less thick than the gel. I don't think I'd get these drops again with these other options. I don't dislike them, but they just don't provide the same amount of relief and longevity as some of the other options. It's also smaller than the Ultra so I get fewer drops out of them. They seem to be smaller so they produce less waste, but not by much. They're very easy to use, but all of these disposable drops produce waste of materials and some product gets stuck in the twist cap, so there's always waste there as well. The Ultra is no different. Overall, I'd probably never use these unless they serve a particular purpose that I'm unaware of.
