I have only used two pairs of glasses for around 12 years, I replaced my old ones only because I left them at the gym and never got them back. The magic: I just bought the glasses at good place (not the most expensive brand in my country, but quite decent) and picked the "greatest package" of features. They offered me like four features to pick from: - anti blue light - scratch resistance - scratch resistance level 2 - something else I don't remember but sounded useful so I picked them all. The frames wasn't anthing top-branded so I paid like $200. The prices may differ around the world, I know but it's still lower than any mid-range smartphone and I suspect it should be similar in most of the world. I used to use a t-shirt without any fluid for years (results were good enough), but since covid I clean my glasses with hand sanitizer with 60% alcohol (water based, not that jelly thing that would smear the view) and 4-layered tissues, the softest ones I can find (I have allergy, so I use tissues all the times, so just by "coincidence" I always have the softest tissues you can find with me). Scratches? I can see a few, I suspect they all happened when I dropped my glasses on the concrete. I once sit on my glasses, I once dropped something heavy on the glasses I left on the floor near my bed. Frames got bended and they don't keep on my head that good anymore, so I drop them like twice a month, especially when I'm working physically on something. But still don't get scratches even by that. For contrast: My girlfriend bought the "greatest package" in a quite no-name shop (but with high rating on Google Maps, everyone is recommending the place), paid around 80% of what I paid, just because she liked the frames they were offering. After three years her glasses are scratched like hell, they look like a thing made from scratches. It's definitely time to replace them. Idk if she ever dropped them, she cleans them the same way I do. But those tiny scratches are definitely caused just by cleaning. So to everyone I recommend trying to find a good store for your glasses and spend bigger amount of money on them. If you're replacing glasses every two years your investment on something better will return fast. If you are low on money - prefer good lenses over looks. It will still be cheaper than ultrasonic cleaner and easier than treating your everyday item like an ancient artifact :)
