FWIW, for my 'murican comrades - I bought the $10 variety of these
microfiber cloths and have been quite pleased with them. They're actually heavier than most microfiber cloths and do an excellent job.
My eyes are so bad that I could not wear glasses were it not for light-weight plastic lenses. In the past the description "coke bottle bottoms" did not do justice to describing how thick my classes were.
Of course, YMMV.
