These black-frame dark-lens men's Locs gangsta shades look as rectangular as you could imagine. The way these glasses are designed makes them the perfect opportunity to blend in with all of the other items you have in your wardrobe. It's better to have a set of shades that's of a neutral color than to roll the dice and go with something that's far more daring. There are small metal logos attached to both arms of these sunglasses. The tint of the lenses is very dark, which provides light-sensitive people with an extra level of protection.
