Hmmmm........the vendor website you link says these are safe on non-coated glass. Nearly all photo lenses are coated. Also take note that the towelettes are made of paper, which is probably the reason for the warning about lens coating. Safety eyewear is usually hardened, and therefore compatible with this product, but I did in fact damage the coating on a pair of safety glasses using this very product. The coating took on a mottled appearance after a while. I know a lot of credible photographers use similar products, but I am reticent to use them on photo lenses.
The materials I use to clean photo lenses are not expensive - isopropyl alcohol and cotton Q-tips. I imagine you could also use clean cotton cloth instead of Q-tips, but I find the Q-tips to work pretty efficiently.
