The Third Eye Bar End Mirror was invented by Malcom Brown after a friend of his died from being hit by a car. He sold it for a while under the name Safe View. Bicycle Safety, Inc. took over the marketing of it a number of years ago, and it has always been successful. The Third Eye Bar End Mirror has a 3 inch convex glass mirror with an aluminized reflective backing. The convex mirror gives you a wider range of view of whats behind, more than a flat mirror would. Be aware that vehicles may be closer than they appear.
