It’s the best—and great for your Oakleys too.

Dear 2020 Euro Lens Bath,
Greetings. I’ve been using 2020 Euro Lens Bath on my eye glasses for about 2 months now. It’s the best thing I’ve found so far. It does a very nice job of cleaning glasses, and I like the fact that my nose pads get cleaned at the same time.
My question is about my Oakley sunglasses. Will your product SAFELY clean them without any residual affect?

Dear Charles,
It’s completely safe to use 2020 Euro Lens Bath with your Oakley sunglasses. Our Lens Bath is specially formulated to protect both the lenses and coatings on all sunglasses and prescription glasses.  Simply place your sunglasses into the washer and shake gently—it shouldn’t take much. Then dry them with the micro fiber cloth using a very light touch. It really is the superior eyewear cleaning solution.

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!

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!
