Contrary to what hoxhunbe just wrote, the cheap crap is NOT ok. Cheap sunglasses do not block out UV rays. As a result, you put the glasses on because it is bright out. To compensate for the darkness, your pupils dilate and let in even more UV light than if you were not wearing the sunglasses in the first place. What's the big deal with UV rays? Well, besides causing skin cancer, as far as your eyes go, exposure to UVA and UVB radiation can cause cataracts, muscular degeneration, and ocular cancer.
i simply meant that they're fine as per the parameters of the OP's question, namely durability. And they are. However, your points are absolutely crucial to the advantages checklist when considering high-end eyewear. i myself should wear the better pairs I've got more often, but the cheapos sit in the drop-down sunglass holder in the ceiling of my truck, and I'm just a little too uncomfortable keeping the good ones up there. So, if I'm out driving and it's bright and I've forgotten my Ray-Bans, the dime-store pair does in a pinch.
