I've had these glasses for about a week. I have really liked them so far. They really make everything clear and colors stand out. I have never had a pair of blue light blocking glasses before, so I have nothing to compare them with on that aspect. Great for driving while cloudy or sunny, but not my favorite outside in direct sunlight. Pretty well built for a $10 pair of glasses. I'm a pretty big guy and these are on the verge of bring too large for my face, so may look huge if you're a small person. The arms are borderline too short to fit behind my ears comfortably. If I lost these, I would likely replace with the same product, I like them so well.
