The large size makes polishing much easier. They reall are head and shoulders above other microfiber cloths.

While birding, i need to clean my eyeglasses, camera, and binoculars frequently. These are the best cloths i have ever used for cleaning my glasses. When cleaning glasses they smear much less than other cloths.

They work even better if you use a lense cleaning solution with them. I have anti-reflective lenses and they work very well for them. The best thing about this microfiber cloth is that it doesn't have a pile.

Clothes are absolutely horrible for polishing clean eyeglasses. Not worth sending back. Paying for the name. Too expensive. Less than impressed.
