They are not only very good, but they are also polarized, which adds a whole new level of clarity to my vision while wearing them. Speaking of the lenses themselves, I am extremely pleased with their quality.
Their customer service was top-notch and they promptly helped me reorder a new pair of lenses. I recently ordered a new lens for my Revo sunglasses, and I must say I had a fantastic experience! Even though the lens initially arrived slightly smaller than expected, it was no trouble at all to get in touch with the team and resolve the issue.
