What you are looking at here is not an ordinary sun visor, but a polarizing one. This is what every driver needs. Firstly, the visor screens out harmful rays of the sun. It effectively removes the glare that is so disturbing on the road. Secondly, the visor is flexible, it can be rotated 360 degrees and set up as desired. Well, and the mechanism on the spring allows you to easily install the protection on any size standard visors. Thirdly, it reliably protects not only your eyes, but you from harmful ultraviolet light. So, if you are tired of going blind on the way to work or you are tired of frying in the sun, this useful little thing will be a real salvation.
