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.
