You get what you pay for. Buy quality once, buy crap over and over and over.....

Ive seen 30.00 sunglasses that block 99 percent of uva and uvb. So its really hard to see the difference in quality for me.
Even the $2 version will block UVA and UVB if you look for that kind of protection. However, do those $30 models feel comfortable when you wear them? Do they keep debris out of your eyes when you wear them? Do they scratch easily? How long do they last?
I typically get about 8 years out of my glasses wearing them essentially 24x7. Will yours take that much usage before they fail?

Now ive had real cheap sunglasses before and they gave me a headach and made me feel kinda sea sick..does anyone know what thats all about?
Distortion you may not even notice. Then their is the light transmission issue. Do they block UVA and UVB uniformly across the surface of the lense? They may look
cool 
but, they may in fact damage your eyes since they cause your pupils to dialate and don't block UVA and UVB properly, actually allowing more UVA and UVB into the eye itself.

High end

I've never thought of it like that.
I am probably a little bit of an extremist on this issue because I literally am not blind today because of good quality glasses. I took a bolt welded onto a piece of square tubing right into my right eye (my good one). It buried the lense, which did not crack or shatter, into my eye socket. Of course at that point I was severly dazed and peeled the mangled eye glass frames off my head and pryed the lense out. That whole thing was a strange experience because I was so dazed it didn't really hurt for at least an hour. Anyway....I feel passionately about eye glass safety.
Most people get suckered into slick advertising campaigns when they buy sun glasses. Am I hip, cool, etc. is all that seems to dominate in the marketplace.
Why are buying sun glasses? Is it the cool factor factor? Are you trying to be trendy, as many people do? Do you want something that keeps airborn particulate matter off the eyeball? Is glare or harsh sun a problem where you live? Do you value the safety from physical impacts (skeet shooting, work environment, etc.)? Then there is the overall comfort and durability issue?
If you frequently loose or damage glasses, then a "good" pair may not be a good investment. Like myself, if you get a good 8 to 10 years average from eye glasses, frames, lenses, then it is in fact cheaper to wear better sun glasses.
I love my Titanium frames. The eye glass shop adjusts them to fit my head and I literally cannot bend them out of shape. Sit on them, sleep in them, rip them off your head by one ear piece ... whatever, they don't loose their shape.
I also like the changable light lenses. Very dark outside, soft tint inside under harsh flourescent lights, all without any action on my part.
Headaches? Never
Glare burns? Never
Squinting? Never
etc.
You get what you pay for assuming you go to a reputable eye glass shop.
