That's true, glare could be a huge problem, too. I'm pretty sensitive to bright lights and always need sunglasses when I go outside, but I never wear them when I ride for some reason. I'll give that a try next time I'm out when it's sunny.

Chile Pepper, yes I am riding a road bike and have no visor on my helmet, but that's a very good point. I'll pay more attention to my neck tilt next time. Maybe I'm crouching a bit too far?
