In the 1998 movie Fear and Loathing in Las Vegas, Johnny Depp wears Ray-Ban RB 3138 Shooter aviator sunglasses. The glasses in the film have custom yellow glasses, but the model itself is still widely available.
Very similar to the Ray-Ban 3030 Outdoorsman, these Shooters have a little ring between the lenses, apparently this helps during hunting or shooting, hence the name Shooter. If you can explain how this works, please contact us.
