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

العلبة كانت مفتوحة ومتسخة وشريط الأمان كان مقطوع

Best solution I have ever used. Been wearing contacts for 66 yrs.

I like his better than other solutions for gas perm lenses. I find it to be non irritating and my lenses don’t seem to get any build up. I have been using this product for about 6 months.

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.

My wife has worn hard lenses for 50+years. She had regularly used Boston. Had begun to experience numerous problems with her contacts and thought about giving them up. A friend suggested she try Unique pH. The results were immediate and the problems she was experiencing were gone. Extremely happy and satisfied with this solution.
