I have a Take-a-Look Mirror also, and just love it! They do come in different lengths too if that helps you any. The first one I purchased was the regular length shaft mirror. It was too short for me because it felt like I was nearly crossing my eyes trying to look sideways into the mirror. I then bought the longer length shaft, ( I believe it's about an inch or so longer ), that gets the mirror out in front of your head further. That did the trick for seeing the mirror more easily. They also have a helmet mounting kit if you prefer to mount the mirror on your helmet. I had a different mirror mounted on my helmet, but it always seemed to get knocked out of alignment too easily on the helmet. I find that mounting the Take-a-Look Mirror to my glasses suits me best. No vibrations/shaking of the mirror, and you can always see what's behind you. Steady as a rock. I have a Mirricle Mirror mounted on the handlebar, and it has too much vibration to see what's behind you except when a vehicle has its lights on. Of course high pressure tires are unforgiving as far as vibrations on all but the smoothest of road surfaces. You may be able to put some type of "heat shrink tubing" on your glasses temple piece that would allow you to fit the Take-a-Look Mirror to your glasses temple piece.
