Oakley Range Photochromic sunglasses
My outdoor sunglasses.. they are huge ! but the distortion is minimal, clarity excellent..
the downside of the large lens is they do fog up on occasion if the wind drops.
These are non polarising reactive lenses.. so they darken with UV light. being non polarising is great for digital photography as I often use circular polarisers on my lenses and polarising glasses would result in weird effects through the viewfinder!
