Its extremely hard to find wipes that won't scratch or otherwise damage expensive glasses or camera lenses or even monitors. The tissues are made of a microfiber paper, and soaked with basically diluted isopropyl alcohol with additional non-abrasive additives.

They're also large enough to get the job done. One packet is enough to thoroughly clean one pair of glasses (both lenses, front and back), and is more than enough for a large professional camera lens.

One is also enough to clean smudges off a monitor if you don't feel like cleaning the whole thing, although I do not recommend trying to do a regular monitor cleaning with these: get a microfiber cloth and mix up a batch of half and half 90% isopropyl and distilled water if you want to do that.

These are great, they clean without streaking, unlike the Zeiss wipes. Don't waste your time or money on Zeiss brand or any other although I have only tried the Zeiss and these. Point is, these work, not so sure about other brands aside from the Zeiss, but the Bausch & Lomb wipes work without streaking. I have experienced some very minor streaking which is barely noticeable, far from the Zeiss brand. I've found if I just use the corner of the wipe on smaller surfaces such as my small sized glasses, and lightly polish until dry, no streaks. Then quickly use the rest of the tissue on other items such as another pair of glasses, camera lens, or whatever, then I'm good to go. On bigger surface areas, such as my wide angle camera lenses or Raybans, I can use more of the tissue without streaking.

These lens cleaners are wonderful. Being pre-packaged in individual foil wraps means that they are always fresh and most when you open them. They'll leave your glasses clean and sparkling.

My husband and I both use these and love them. We bought them first in a big membership store, but when the store started selling an inferior brand we had to hunt around. I'm really glad they are on Amazon! I just bought six boxes (of 100 each) to make sure we have a good supply! They are wet enough to do two pairs of glasses, but dry instantly and streak-free!

I have glasses with an anti-scratch/anti-reflective coating. At first glace these wipes do an OK job -- but I did a lense/lense comparison with Zeiss Ultra Clarity wipes, and the difference was dramatic. The B&L leaves a cloudy film -- the Zeiss treated lense was sparkling clear.
