First of these lenses are from eye glasses.
second, the ink stain if from a ball point pen I think and some of the ink stained by glasses lense while I was doing my homework, I tried cleaning the glasses with a lense cleaner, and water. I even used my lense cleaning solution and most of it is gone but some of it is still there so I was hoping one of you could give me a safe, scratch free solution to getting the stain off.
