Purilens Plus Saline - Unisol 4 Replacement - 3 bottles x 4 oz

As far as I know, this is the only game in town as far as no preservative saline solution. To make a hole for the drops, you twist the top. If you leave the little white plastic piece around the neck of the bottle while making the hole, the hole is smaller. Take it off while making a hole, it's a bit bigger. The saline solution seems the same.

Too much in one bottle. So wasteful for the short life to fill lens. Not buying this again. Makes it too expensive to use.

I have keratoconus and scleral lenses. My eyes are very sensitive to Salines so Unisol was my only option. Now that Unisol is nearly impossible to find, I decided to give this a try. I must say that this solution gives my eyes the same refreshed feeling that Unisol did and for a fraction of the price!My eyeballs and my wallet are happy... thank you Purilens!

these are good, convenient bottle for travel, hard to find saline these days. of course, you don't really need these; saline is exempt from tsa rules. but they're a good size for trips of a week to 10 days anyway.

I was panicked when Unisol 4 was no longer available as I respond negatively to so many products with preservatives. Purilens was recommended by my optometrist as a comparable substitute. This is was a pleasant and comfortable substitute for Unisol 4. I truly love this product it makes wearing hard contacts comfortable!

Purilens are not sealed bottles. They have no foil seal and no click tamper turn cap either. The merchant is saying they are sealed because they seal them in a plastic baggy. BS! I have keratoconus and schleral lenses so I rather use addipaks (100 5ml individual vials for less than $18) than these things. One vial is good for both eyes once a day. So twice a day and I get 50 days worth of sterile preservative free saline. Don't trust anything without a seal. Technically its not sterile then. I tried these in my eyes (the solution sits behind my eyes while I wear my lenses...) and it makes my eyes itch and prone to eye allergies.

This came in a pack of three, which is great if they didn't expire within a few months. I ended up having to throw away the last bottle. CHECK EXPIRATION DATES if you order these.

The caps are defective and do not puncture the top so you can get the saline out. Easily fixed with a needle - but that is a process that should be unnecessary... and was a bit of a problem for us when we took a fresh bottle on vacation and then couldn't open it.
