This washing system keeps my glasses in great shape, they are completely clean and it lasts forever! I love that it gets my make-up and oils off my frame, and the lenses are CRYSTAL CLEAR!

5.0 out of 5 stars.  “The best solution for cleaning eye glasses.”, April 15, 2011

Really Effective – I kept scratching my lenses and wearing off the expensive coatings — but I needed to see clearly. What to do?
I spotted the 2020 euro lens bath and gave it a try. Now I can’t live without it. It’s easy to use and really leaves my glasses feeling and looking very clean — and it seems my glasses stay cleaner longer during the day too. After a year, my lens coatings are completely intact and my lenses are still almost perfectly clear of scratches (I blame myself because I still slip and use my old “shirt tail” cleaning method at times). I don’t think there is anything else like this out there. This truly is a “best-value” product.

I was a skeptic at first when a L.A. friend of mine gave me a bottle to try. I love my glasses and am obsessed with keeping them clean. They seem to attract all kinds of crap just sitting there reading. So I throw the glasses in this bottle and shake it up, pull them out and BAM! I wipe them with one of those lint free micro fiber cloths that come with it. Change the water frequently cause it can get real funky after a couple of weeks. Most people simply don’t want to take the time to do this and they just throw some tap water at them and wipe them with a piece of random paper that ends up scratching them. I say order at least 2!
