This clever Fresnel Lens device allows wide angle vision of blind areas close to your vehicle which would normally be blocked from view.  Mount this in the rear window and you'll see that child directly behind your vehicle. Mount one in your truck side window and you'll never miss a small car or cyclist beside you again! No back-up camera on your unit? No Problem. This will help relieve blind areas! If there IS a camera, this will add additional coverage to your environment. Does NOT block vision like a safety mirror can do - it's transparent!

View angle: Upward + 13 degrees.  Downward + 27 degrees. Side view adds 25 degrees of visible area.

Made of soft optical PVC material, it is easy to mount, and safe to install and use.
