Lens manufacturers say that anything other than a microfiber cloth will damage the coatings on a lens. But microfiber cloths eventually pick up crap and they look like they're a pain to wash.
How do you keep your lenses clean? Are you using cloth/kleenex or microfiber cloths? If you use microfiber cloths, how do you clean those?
Never had that issue but I pretty much only ever bought Bounty or BJs store brand. Also I basically only buy Zeno glasses and my prescription isn’t complicated so IDGAF about the lenses.
