Hi Andrew,  I have a patant for sunglassas that are "State of the Art" and I'm still looking for a company that would License   the above. My patent is "Unparelleled" not only safer to the eye's rays, it Blocks Blinding Glare. Don't mean to get carried away.   I'm looking into "Maui Jim Sunglasses" they say they are a pvt. Company. Jake
