You could easily find actual "safety glasses" that could still be "matching" and look cool. Something like these:

However, the idea remains the same - hardware stores (i.e. Lowes/Home Depot where I'm at, or any similar store) should carry a variety of different looking ones you could get for your drive team that would still match each other and give a cool "look". Best of luck to you!
