I purchased a gold iridium lens for my oakleys from a online moto store, and when I bought them I expected a mirror finish, but in the house i can see through them, is this normal? I put them on and hobbled to the door and looked out, and it seemed like I had a pair of "blue-blocker" sunglasses on. I thought they were for bright sunlight. Anyone have a lens like I have, and are they as described above?
