Take-A-Look Cyclist Mirror
If you want to use a mirror on your eyeglasses, the Take-A-Look Mirror is what you need. They can be adjusted so you can look into the mirror without straining your eye. Take-A-Look mirror features three pivot points for multi-adjustments and the perfect fit. Provides optimal viewing with wide field of vision. Durable stainless steel and brass frame with an optically correct acrylic mirror.
I've tried several cyclist mirrors out, including those mounted on the bike and helmet and this mirror has been the best by far. It provides for easy mounting to the arm of your glasses (the best type of arms are those which are flat) and easy adjustments. The view for whats coming up on you from behind is excellent, clear and easy to focus on. A cyclist riding any road which is travelled by other vehicles should not be riding without a way of knowing what's behind and this is one product that will serve you well. I'd recommend this mirror to all my cycling friends
