Maui JimKeokea W/Patented Polarizedplus2 Lenses Square Sunglasses

Ordered the tortoise directly from amazon. The lenses appear to have a wide horizontal strip of discoloration going across the middle. Is this normal?

Aren't these unisex and not women's only? The official site only has one listing.

do these come with a case?

What’s the Lens height for Kobe’s?
