PurilensPlus Saline - Unisol 4 Replacement - 3 bottles x 4 oz

built like it should be, solid performance and a hole punch that creates reliably round holes so the stream is consistent. Expensive for what you get but it's better than nothing and more solid than the old Unisol. Maybe getting it locally would help that.

A preservative-free saline that is exactly what I needed for my hybrid contacts. It's a great product, works well, and the multi-packs are fantastic.

Acceptable replacement for Unisol 4.

I was happy to find this after Unisol 4 became unavailable. It seems to me to be identical to the Unisol. The mechanism for piercing the bottle is easier and more effective than the one on the Unisol 4. It arrived even more quickly than promised.

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.

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!

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.
