Boston One Step Liquid Enzymatic Cleaner, Preservative-Free Protein Remover for Rigid Gas Permeable (RGP) Lens, Sterile Single-Use Dispensers, 15 Count

I can't use Boston contact solution. It irritates my eyes. These vials I can use though. A simple, effective cleaner. Put a drop in each well with saline and let them sit overnight. Rinse in the morning and enjoy comfortable RGP lenses. If you store hygenically, you can get two or three uses per vial. I don't like the plastic waste but the product is great.

Do you wear extended-wear contact lenses? I do monthlies because of travel and in case I forget to take my lenses out, and monthlies worn for long days or for multiple days straight can get very stubborn to remove protein and lipid deposits. Enzyme cleaner to the rescue! I use an ultrasonic lens cleaner daily, and it's OK, but I still need to use hydrogen peroxide cleaners semi-regularly, but even all of that does not remove all of the deposits, so by the time week 2 of lens use comes around, even if I avoid sleeping with the lenses in, the lenses cloud up and I can't see distance for crap -- my uncorreced distance vision is stil better than 20/20 - this is mostly for reading due to eyestrain and I prefer contacts for the wider field of focus. I've scrubbed the lenses like my opthamologist recommends, and the ultrasonic cleaner was a yuge improvement but still not great. Even combining scrubbing, the peroxide cleaner, followed by opti-free in the ultrasonic cleaner, doesn't remove all the deposits. I knew an enzyme cleaner would take care of this but I've looked for enzyme cleaners for months and could not find any at Sprawk*Mart, CVS, Walgreens, grocery stores, costco, Sam's club, etc. all to no avail. I electrophoresis could also break down the proteins, but electrophoresis contact lens cleaners are BRAND-new on the market and don't have a long track record -- I knew what eletrophoresis is I didn't even know until last week it was possible to use for cleaning contact lenses, let alone that such cleaners are on the market now. But when I was looking for a different ultrsonic cleaners or other contact cleaner methods (and being gun-shy about the expensive electrophoresis cleaner due to lack of in-deoth reviews) I spotted this Boston enzyme cleaner The Boston enzyme cleaner arrived yesterday - and I was cautiously optomistic. I took my contacts out earlier in the evening than usual, did a pre-scrub, dropped them in the ultrasonic cleaner, added opti-free, and since it uses about 4x as much cleaner as individual contacts cases, I put in 8 drops of enzyme additive, and let it sit. This morning, I dumped out the cleaner, refilled with opti-free and dipped the lens basket back in the cleaner for a final rinse, skipped the usual post-soak manual scrub, and looked at the lenses. They looked brand-new! (this is day 23 for these lenses, and they've been worn overnight twice this month and even accidentally showered once). I put them in- they felt brand-new. Visual acuity: crystal clear reading, no light haze, and my distance vision is only mildly degraded from the lens (my distance vision is still very good and even after trying about 8 different presciptions, we couldn't find any that don't degrade my distance vision at least a little bit). Even with the peroxide cleaner followed by a manual scrub, then a few minutes in a bath of opti-free in the ultrasonic cleaner then a final manual scrub and rinse, the lenses usually freel gritty at the end of week three, and have a light haze when I am in a dim room and a light is hitting my eyes, and difficulty focusing distance. There is None of that with this enzyme additive; they're just like brand-new, day 1 lenses. I'll get the electrophoroesis cleaner later as I expect that would be even better (possibly even allow using a single pair of lenses for multiple months!) but this enzyme cleaner is a real game changer. The extended wear lenses have gotten so annoying I've been debating switching to weeklies or even dailies to avoid the gritty feeling and clouded vision, or simply wearing them ONLY for computer work This enzyme cleaner ended that frustration.

I've used this product weekly for years! Lately it's been difficult to find in my local drug stores, so I'm so happy I can purchase this from Amazon! This product it easy to use. Just soak your lenses over-night in the solution and the next day your lenses will feel so comfortable! Try it.. you'll like it!

I wear gas-permeable ("hard") contact lenses. They are not very common today as most wear disposable contact lenses or get LASIK. My lenses work well for me but they need a lot of care and products including this Enzymatic Cleaner. It has disappeared from regular stores such as CVS and Target. Very pleased and relieved to find it here and price was very reasonable too.

This review is for the enzymatic cleaner. I have found that it's essential for my contacts. After I use the cleaner, I can see more clearly than before and my contacts feel more comfortable. The cleaner is quick and easy to use. It comes in individual plastic capsules with approximately 4-6 drops in each one. Each contact requires 2 drops each. After soaking them overnight, I rinse them with my conditioning solution or sterile saline solution. The nice thing about the capsule packaging is that they can be easily packed for travel.

Been using for a very long time. I can feel the difference once used. I was worried about getting expired or near expired but no issue. I will use them well before exp date.

I love these convenient, one time drops! I keep a few vials in my purse for when my eyes start to feel gritty and need rehydration. I think they are little expensive for the quantity when compared to multi-use eye drop bottles, but they are convenient, especially if someone asks if I have eye drops! You don’t want to share a bottle you use, so having individual treatments is very nice.

It’s an awesome enzymatic tear protein cleaner that cleans the lens like new. It extends the contact lens’s useful lifetime. It feels so comfortable after the lenses are cleaned. It reduces the foggy lens buildups caused by tear secretion. The more tear deposits on the lens, the more the eyes tear up, making the lens worse to wear and throw them away. When it feels like new after cleaning, it gives you much better vision for the lens. There are hardly any other options for cleaning the tear protein deposits on the lens, which cause your eye to tear and fog up. The only other product that cleans the protein deposits is bromine, which is not indicated for soft lenses. The sterile single-vial can be extended for multiple uses if you keep the vials in a sterile condition.
