Biotrue Hydration Boost, Preservative-Free Eye Drops for Dry Eyes, Instantly Moisturizes, Rehydrates, Contact Lens Friendly, Refresh & Relieve Eye Irritation, 0.33 FL Oz (Pack of 1)

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.

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.

The first time I use these eye drops was night and day totally different from other products. They did a great job lubing my eyes for several hours. I didn’t need more than one to two drops in each eye. It was a complete game changer. I could see clear my eye stopped burning. They’re extremely effective. There was hardly any smell. The use is phenomenal. Easy for travel. I’ll keep it in my purse all the time it does give a cooling effect to burning eyes. The quality is higher than most. The price is very desirable for what you get..

Product works great, but the dispensing method is not great. It does not do well creating droplets, mainly makes a stream. Sometimes it doesn't do anything when I squeeze it. My eyes are doused by the time I actually can get a drop or two in the eye. My wife loves their products for contacts, so gotta give them at least that. Maybe I'm just not figuring out the method, but it shouldn't be this hard to do. Just a warning to anyone who could have the same issue. Eyes feel great once I get some in them!

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.

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!

Ok so I've read reviews that says the bottle is hard to squeeze--I ignored it because I feel like all eyedrops bottles are annoying or at least the ones I've used so far. My biggest gripe with this is the amount of eyedrops that comes out. It gets all over my face every time I apply this. It's just too much. I will have to say it is hydrating for my eyes or at least slightly more hydrating than the one I'm currently using. It also doesn't have a pointed tip which makes it hard for me to apply the eyedrops Edit. It's been like 2 weeks and I'm done with a fourth of the bottle because the drops come out to big and then ends up all over my face I currently use iVizia eyedrops and I hate the bulky packaging of it which is the only reason why I'm trying other eyedrops. I will not be repurchasing these which is a shame because the packing is much less bulky than what I'm used to.
