whats the length of this product from forhead to chin?

If you only measure the visor, it is 7.1 inches; if you include the sweatband, it is 8.5 inches.

Does it easily adjust and fly into face/nose when used for running?

Easy to adjust nd no it doesn't bother while running...i use it for walking nd it doesn't blow away nd good when rainy

is there a protective film on the front of the shield as well as the back....If so, I cannot find how to peel the film off

Hello, I apologize but I cannot recall if there is a peel off film on the outside of this product. I purchased it for three reasons: 1. It is polarized, 2. It is one of the least expensive shields than the ones in my dermatologist office and 3. I can still read my Kindle while I lay out in the sun. Is there a way to contact the seller or distributer of this item? I will try and see if I can find the paperwork that came with the visor and see if I can find anything on the initial directions. Warm Regards, Veronica
