interesting robow, I always kept in mind the "no dry" thing for lens cleaning, I worked in photo for many decades and always took extra care with my expensive lenses, specifically for the anti glare and reflection coatings on them, and making sure you arent doing the sandpaper thing applies the same to eyeglasses thats for sure.
Going back to my motorcycle days, having a really clear visor , and with bicycles, very clear, non scratched, sun or clear glasses, is a real priority for me, so taking care of my sunglasses is super important.
good point to bring up.
Now if people care or make the effort, thats a different matter.
