I wore my take-a-look eyeglass mount mirror again. I really hate it, no offense to the inventors. Has anyone else gone through this? I take a really long time getting it into a position where I can see the car behind me when I'm in a bike lane. But when it is positioned well, I normally can't focus on it with my left eye without closing my right; and when I have it mounted I'm always looking out for some notorious cyclist killer when I hear a car coming, totally killing the fun of riding my bike. It sometimes sags from my glasses (I use the mirror on my prescriptions and sunglasses) and I hate taking off my glasses to adjust the mirror when I'm at an intersection and the light might turn green any second.
Are bar end mirrors really that bad? Do they make you straighten up the bars and lean away to the side just to get a clear look behind? Are they also difficult to adjust? I always look back before changing lanes if I just checked my mirror, but I feel like there are many situations that would make me grateful for having a mirror before looking; like when you need to switch lanes but you do not know if any cars are about to pass you or how close they are passing.
Does anyone use any different methods for looking back while riding on the road? I'm well familiar with the "stand up on pedals and rest chin on left shoulder" method, since I'm currently dodging the eyeglass mirror.
