Can someone please help me out by giving me a name for the specific glasses style in pic related.. they are not exactly what I want but very close. I want sunglasses that have the rectangular glass but they are not polarized or are very lightly tinted so that I can use them at night. I've been searching for them by "rimless non polarized sunglasses" but nothing turns up. I want something stylish like this that looks good that I can use almost daily and go out with.

Also in the sunglass world is there a scale for polarization. Like say I want to look at sunglasses with only a very light tint is there a scale that is used?
