Bike Peddler Take-A-Look Cyclist Mirror
The best rear-view mirror on the market, allowing you to have a constant view of what's going on behind you. It easily attaches onto your glasses or helmet (you'll need the helmet adapter), and all you'll need to do is adjust the pivot points to the correct angle. The frame is made from superlight and durable stainless steel and brass, and is specifically designed to minimise vibrations. It's adjustable for left and right-side use, and the optically correct acrylic mirror has a wide field of vision so you'll be able to see everything.
