It really depends on the lens. If you get Polycarbs, UV protection is part of the material. However, if you choose CR-39, then UV needs to be added. I've ordered four pairs of glasses from Coastal Contacts and I find their coatings to be terrific. I've never specifically noticed anything with the UV coating but my Uncle, who is an Opthamologist, says they are superior in their coatings. With that being said, Coastal Contacts does have a great 30 day return policy. I don't think you can go wrong.
