Unique pH Multi-Purpose Solution + RGP Lens Case. TWO 4 fl oz (120ml) bottles

The viscosity is different and advantageous. I noticed the difference immediately -- much better than other products I've tried, and it was particularly effective when I lost a lens and had to quickly prep a backup lens. I soaked the backup lens for a mere hour -- it slid into my eye without irritation and remained irritation-free. Yes, this is observational, I cannot offer scientific evidence because I have none. By my experience, the product works better and faster and I will buy it again.

Very expensive for what you get. However, it work for my gas permeable lenses.

My husband has 3 different eye diseases and he has used this for 2 full years, beginning the 3rd. He has been extremely grateful for this product! Thank you

At my last eye exam, they had this solution for use in putting the lenses back in at the end of the exam. WOW, it was comfortable. Very light feeling. I asked and they had sample bottles available. I tried that and was hooked. I've been wearing hard lenses (now, RGP) for right at 50 years and this is the most comfortable soaking/wetting solution I've ever used. Been using it for 8 months now and still think it's great.

Good quality solution!
