I chose the bespoke Alutra lens for flying. The sunglasses sharpen everything, taking any glare away. They react so fast to different light conditions, but you don’t know they are reacting. I forget I am wearing the sunglasses, they are very comfortable. “When buying the sunglasses online, it was very reassuring to have an enthusiastic and knowledgeable person at the end of the phone, giving me the confidence to make a purchase. There’s no going back now, Bigatmo are great as sunglasses for pilots, and I also wear them everywhere else too!
