Brown lenses do not trap as much light as a grey lens, which makes them perfect for most outdoor activities. The brown polarised lens cuts through glare while still providing enough light for the wearer to see detail on the land or on the water. Brown lenses transfer light well and sit in the medium light transmission category. Brown lenses are useful when scanning the water for fish or off-roading and general road driving where shadows can sometimes quickly change the available light. The brown lens delivers close to the natural colours you would see with the naked eye making it comfortable all day long.
