I break and drop and lose sunglasses constantly, I have to buy 3 or 4 new pairs a year so I’m not interested in buying anything expensive. Until recently I bought some Chinese 5 euro crap but I would prefer to buy 10-15 euro EU made crap. Is there anything like that available?
Have you tried analyze why you break so many? Maybe there is something you could do that would be even cheaper than buy cheap sunglasses?
I break them in whatever fashion you can imagine because I forget I have them with me and sit on them, i throw them in my backpack and then smash them with 6 pack of milk, I put them in a pocket with keys and they scratch. Most of the time I just leave them somewhere because I forget about them. Idk what could be cheaper than buying them cheap.
Maybe get a glass case? I have one (two) in my messenger bag, never broke my reading nor my sunglasses, no matter how badly I treat my poor bag ;)
There are hard case and soft ones, depending your usage.
