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?
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.
I used to do the same when I bought cheap sunnies. I went on a whim and purchased a designer pair, and have had them 10 years now. If something has more cost, you tend to take care of it more. At least I do.
