Sorry, forgot the other part of your question when describing tint. There is an estimated warehouse receipt in the first week of May, 2013, for more stock of the Diamond Supply Co Cordova Sunglasses in the Leather/Gold design.
It might be possible to see the outlines of your eyes through the Diamond Supply Co Cordova Sunglasses, but picking up details might be harder. Depends on the actual lighting as well. So sorta hard for me to say. I would recommend doing a search online for various images of people wearing this style of shades.
