If you are shooting in low light enviroment, this is what you need. You could quick change your regular len off your Bolle goggle to your new lemon yellow len in a few seconds. However, don't wear your goggle over your MICH of PASGT helmet, otherwise the len could fall off from the goggle.
Pros: Easy to change and replace. Brightens up the surroundings
Cons: Minor fog problem, len could fall off from goggle if bent.
