Just right

I have had everything from cheap gas station glasses to Oakley's. This is actually a great combination of both ends of the spectrum. They're not super expensive but the build quality is top-notch. I really like the frames due to the style and color. The hinges are nice and strong and look to last. And then there are the lenses. This is my favorite part. They do a good job of protecting my eyes and removing glare yet not making things so dark that I can't see.
