Tom Ford Half-Rim Optical FT5504 - Seth Rogen
On Instagram, we can often spot Seth Rogen wearing Tom Ford Half-Rim Optical FT5504 eyeglasses.
The glasses have a Dark Havana and Gold frame and have the T logo hinges.
As seen in the pictures and as Seth mentioned himself in an Instagram post on January 22, 2019, Seth Rogen's eyeglasses have "transitional lenses" or "photochromic lenses" - optical lenses that become darker on exposure to sun / ultraviolet (UV) radiation. And in a post on February 12, he says "80% transitioned.", showing the lens effect in the photo.
