Sunglasses Input Requested

I could use a little sunglasses help. With small ears, a flat face and almost no bridge to my nose, sunglasses very quickly slide down to my nostrils. Does anyone have any advice here, particularly as we move into the sweaty season? Oh yeah, I don't want to pay tons of $$ for them because that means I'll lose them more quickly. . .

You should try the adidas evil eye or gazelle,you can get them in different sizes.Yes,they're pretty expensive in europe but i guess in the states they're a lot cheaper.The thing is if you get the right size they'll last you a lifetime.Nostril-inserts and such can be nought seperatly...
