I bought these more out of curiosity than anything, but I really did need a decent pair of driving sunglasses. (I didn't get one).

I really don't understand how sellers like this can be allowed to use such misleading words to describe their merchandise in order to "con" people into buying them. There is no such thing as "high definition" when it comes to sunglasses. Like most cheap sunglasses, all these do is change the color and slightly dim the light that gets through to your eyes by wearing them. The color of the lenses is such that they will give you a little different look at things, by coloring the world yellow. And now that the novelty is over, I'll probably throw them out.

They are cheaply made, feel like they would scratch easily (although I haven't tried to scratch mine to test this), and I don't really expect anything long term out of these. It's no wonder you can find a pair for as little as about $4 bucks.

They deserve one star because there's no option for no stars. Save your money.
