I believe I purchased these about 20 years ago. The lenses are the same as when I bought them. When I wear them, they cover my eyebrows, and I thought they would be great for hiding my bare face. However, I mainly use sports-type sunglasses, so I haven't had many opportunities to wear these, and I've only used them a few times. It seems this company is no longer in business, but they were well-known in the eyewear industry. When I took them to a local optician I frequent, they raved about them, haha. These are licensed products, so there is no authentication. I have an extra Saint Laurent glasses case, so I'll include it as a bonus. There is no glasses cleaning cloth. Shipping will be on weekdays only. Thank you! ^ ^
