They do ,
when a newer variant come out , and your frame happens to be
spoiled , for example changing from the old to the new straight
jackets.
That one is the oakley display head , im sure
there's an official name for it though , i heard it's made of
expensive materials and in addition , made in USA , costs quite
expensive in comparison to sunglasses though.
Actually the warranty got cover for the lens , but
only for 30 days , that is excluding scratches , but including
manufacturing defects.
