Hi Paula, Yes, the sunglasses we offered at Firmoo are 100% protection or UV400, which means the lens can effectively block all harmful UV. We offer 1.56 index lens for sunglasses and sunglasses can only be used for distance, not for reading, bifocal or progressive.​​​​ You can also check this link https://www.firmoo.com/help-p-157.shtml on how to choose sunglasses for reference. For any further questions or immediate assistance, you may also call our call center thru toll-free hotline at 1-855-487-6006 opens every day from 7 a.m.- 4 p.m. PST.
