The SunBlaster is the revolutionary new dual-lens glare protector that provides instant relief from the blinding sun and reflective surfaces while driving. The SunBlaster is made of durable, shatterproof polycarbonate and attaches to any vehicle visor in just seconds. Solid visors block vision but SunBlaster offers a completely unobstructed view of the entire road ahead while providing protection from harmful UVA and UVB rays for driver and passenger all year long. Helps to reduce headaches and fatigue caused by eyestrain.
