I have this issue with fogged up sunglasses....

It seems like every time I go outside to take pictures, my sunglasses fog up. I try to rely on what I can see only to be disappointed later on with my aperture not being set properly and things either being too dark or blown out. I've tried to edit a few with this issue but I've been getting some really weird tones that people will either really like or not like at all... let me know what you think!
