Light Shield New The First Intelligent Anti-Glare Sun Visor for Cars, Trucks and RVs - Blocks Dangerous Sun Glare and Harmful UV Rays - Anti-Glare Shield for Snow Reflection

Too big and heavy to work on my wife’s Prius visor. She said it DID work @ reducing sun glare (when she could lower it without its weight and sheer bulk interefering with, among other things, the cars steering wheel turning)!Maybe it’s best use would be on the larger and stouter visor of a commercial truck or in the cab of a semi-truck, but NOT in a passenger car !
