    I have a big head! These glasses are wide enough to fit my large skull! I love the way they look and feel. Best glasses I've had yet. The price is great as well. Which is even more important.

    First time buyer with yesglasses. I’m very impressed. The glasses seem very well built. Excellent packaging, case, and lens cleaning cloth. I will be referring them to my family and friends
