Lens cleaning is a small purchase that decides how your glasses look for the rest of the day. This category gathers sprays, pre moistened wipes, microfiber cloths and anti fog products, mostly from ZEISS, along with a Varilux cleaner. All of them are made for coated eyeglass lenses, which is the reason to use them instead of whatever is under the kitchen sink.
Split the decision by where you clean. At home, a spray and a microfiber cloth is the cheapest option per clean and the gentlest on a dusty lens, because the liquid lifts grit before the cloth moves across it. Away from home, individually wrapped wipes are the practical answer, since a cloth left loose in a bag collects the same dust you are trying to remove.
Anti fog is a separate decision from cleaning. If you move between cold and warm air, wear a mask at work, cook, or exercise in glasses, an anti fog spray or wipe does a job a regular cleaner does not. Fogging returns as the treatment wears off, so these are consumables rather than a one time fix.
Rinse or blow visible grit off before wiping, and keep paper towels and shirt hems away from the lens, since both are abrasive enough to leave fine scratches over time. Replace microfiber cloths when they stop picking up, and wash them without fabric softener. If your lenses carry a specialty coating, your optician can confirm which cleaners are approved for it.
