not just for eyeglasses
was looking for a safer alternative to rubbing alcohol for cleaning my laser optics and came across koala kleaner, had to make 2 passes to get the lens clean, first was to clean off the grim /dust  and second was to clean off residue and light streaking leftover from the first step, very happy with purchase and will buy more if i need it, will need to grab the refill later
