Really nice. Great fit and when my son out them on he was impressed at how great the vision through these lens were.
This is my son's second pair of Rec Specs. Having special needs and not understanding why he needs to keep his glasses on, we needed to purchase a sturdy pair with a strap to keep them on and ensure they're durable. Last time I purchased the pair from the optometrist's office. However, this time I ordered them myself directly from the website. I was pleased with the ease of choosing, trying, and returning the samples. I was even more pleased with how quickly the pair I purchased was received.
This is our second pair if the same frames. They are very durable and stylish. He using them for all day safety glasses.
