Judy, couple of thoughts on better coverage for driving without the soft 'spongy' type foam.
One, a couple of the 7Eye frames have a different kind of foam - it's not firm like the Dustbuster but also not porous like the Curv Z. Briza definitely has this, Churada might depending when the store that stocks it purchased their stock. If $99 is not out of the question it might be worth stopping by a dealer to check them out.
Two, EyeEco's moisture release glasses. I don't have them in stock right now but you can check them out at eyeeco.com. They have a 'bendy' kind of frame which flexes at the nose bridge and this means that even without a super-deep eyecup you can get it to fit really close to your face. Also their newest eyecup is silicone (or something like that). They have a dealer locator on their site, maybe they will have a dealer within 10 minutes driving
