I'd like to know if there is any reason that these wouldn't be good for cleaning refractor or eyepiece lenses. The fact that it is a premoistened towelette makes them very portable and handy to keep in an eyepiece case, especially for emergency cleaning in the field. I've used them on my coated plastic eyeglass lenses, and they seem to be very gentle. They haven't scratched my lenses and they do a good job of cleaning them. I'm posting a picture of the front and back of the package.
