The whole idea of 'murdering out' your goggs is to make them ALL black, now if you put in a night lens such as a yellow iridium or pink iridium or blue iridium, would they be all black?
So you have at LEAST two options:
1: Live with not being able to see well at night, cause well, skiing is all about looks and having the hottest trends.
2: Invest some extra cash into a second lens/goggle, allowing you to see well at night.
3: Wrap your head in seran wrap for night skiing, its really cheap, and should work pretty well!
