My optometrist gave it to me to use with a scleral lens, and it works well.
The description says 3x480 ml, and I would have expected 3 bottles of 480 ml. However, it came with 3 bottles of 360 ml and 6 of 60 ml. No problem; perhaps it’s even more practical, for example, for travel. However, the 60 ml bottles said “Free sample—not for sale.” Isn’t that strange?

I only received the large bottles and the small ones were missing, but it doesn't matter, for the price it was good

I have been wearing contact lenses for 20 years. It is the best thing out there among everything available. Especially if you are one of those contact lens users who wear them from morning until the next morning, you should definitely choose this solution. It does not dry out the eye at all. Whenever I have tried some other one, after just 5 hours of use I cannot open my eyes or I get itchy. As soon as I put this solution in, everything ends. Both the itching and the dryness.

I have been buying it for years again and again... I consider it one of the best!!

I find it satisfactory and effective. It is mild, quite moisturizing, and it is very convenient that you can leave the lenses inside even for just a short time before putting them back in.

It didn't fit my eyes at all. My optician recommended it to me as it matches better with the Total 30 lenses from Alcon that I have been using for years. After 1-2 hours, my eyes are completely dry and dehydrated. I will go back to Alcon Pure Moist that I had for years.

This particular solution, in my opinion, does not provide proper hydration, resulting in my lenses drying out within two to three hours, whereas normally I can wear them for up to 24 hours without them drying out

Very good and at a good price. I was using Opti-Free until it became extremely expensive and I switched to this one

It is a good product but far too expensive both compared to competitors of similar quality and for how much it actually costs to produce

I don't know if this happens only to me and with the lenses I wear (Meyers Aqualens Aspheric UV Monthly) but with this solution, I can't last 8 hours without my eyes getting blurry and completely drying out. Something I never experience with Opti Free Express.

I have been buying it for many years.
I like that I don't have to rub the lenses to clean them. With other liquids, I couldn't do that.

Very good contact lens solution. It does not cause irritations and keeps the lenses hydrated all day.

I have been using it for many years. Almost since it was first launched and I consider it the best for silicone-hydrogel lenses.

They sent it to me twice from the pharmacy as a sample, along with the lenses I purchased. Both times, when I used it for as long as the sample lasted, it dried out my eyes and the lenses would quickly become blurry, within a few days. I do not recommend it at all! I simply confirmed that what I was already using is better.

Quite mild product, I clean the lenses with a solution containing exclusively oxygen. However, with that, you cannot take them out of your eyes, put them in the solution for a while to moisturize, and then put them back directly because if you put them in fresh solution, you have to wait 6 hours, while if you put them in the solution they have already been cleaned with, there may be residues. You can also use this directly in the eye if you want, like drops.

Simply the best by far...
After 20 years of using contact lenses, I haven't changed it since the first day I tried it

The best contact lens solution I have ever purchased. It is relatively more expensive than others, but you get what you pay for. At least for this specific product, it holds true

I have severe dry eye and because I don't sleep well, I have a particularly intense problem in the morning. I can clean and moisturize my contact lens and eye about 10 times for fun. I was looking for a contact lens solution that wouldn't irritate my eyes and that I could quickly put my lenses in. I tried 6 or 7 different ones. It is by far the best of all!

I have been using it for about 10 years. Until then, I used Renu, which was good, but if I wore the lenses for many hours or if I took them out and put them back in before 4 hours passed, it would sting incredibly and irritate my eyes. Biotrue has never done that to me and now, in combination with silicone-hydrogel lenses, I have no discomfort in my eyes.

Not only did it cause irritation... It made my eye swell and caused unbearable pain for two days... Redness and itching... Very bad product... I tried it because I ran out of my own liquid and I almost couldn't see... I do not recommend it to anyone

I would buy it again, and I don't think I will change it again (I used renu for years but I think this one hydrates the lenses better)

This particular product does not personally irritate me. On the contrary, it actually relieves me due to the allergic conjunctivitis I have in my eyes (More specifically, I quote the reason I read somewhere: It has a pH similar to healthy tears, thus providing 20 hours of hydration in every drop)..
In terms of price: It's a bit pricey in the market if you look for it outside, so it's definitely worth buying from an online shop.

Exactly the same behavior as Renu, which is from the same company. Irritation and moderate hydration compared to the very good lenses of the company.

No, just no, at least in my eyes it irritates me, the first time I used it it irritated me so much that I had to throw away the lenses

Since I started using it, my eyes would turn red and itch. At first, I thought it was because of my contact lenses, but it turned out to be caused by this product. I do not recommend it.

It moisturizes the lenses very well and I can wear them for hours without being bothered. It is the best I have tried

Many times when I wear contact lenses, my eyes feel irritated. This is not one of the good solutions available on the market. There are much better solutions available at the same price. I definitely wouldn't buy it again.

I had an allergic reaction, and the ophthalmologist told me that it is probably because of the solution, so I changed it and switched to BIO TRUE. My eyes had turned red like zombies. It does not provide ANY hydration!

I had used it years ago for a very short time and it irritated me. Now, I am coming back to it again. Very good! Because I have dry eyes, it helps me a lot, excellent hydration.
Update:
After 1 month of use, I stop using it because it irritates my eyes too much.

I have been wearing contact lenses for 15 years. In my opinion, the above solution is by far the best on the market and the basic one does not contain mercury (thimerosal) like most solutions.
