Sunglasses, why not? Real pilots had them. Shouldn't be a perk either. Standard equipment. The sunglasses if modeled correctly would not eliminate the gun glare. Just cut it down. That's what real sunglasses do. If you want to take it a step farther, it would cut down the sun but also make the instrument panel darker and harder to read. I hate the sun glare and I think it is a hinderance for most players far more than it is an advantage.
