Ray-BanUnisex Original 0RB2140 Wayfarer Gradient UNA Sunglasses (pack of 1)

Do the crystal green lenses really look green or is it more of a gray/green?

Are these 54 mm or 50mm ?

The lens is dark?

What is the temple length measurement for the 54mm? Curious because I have tried these on locally and the temples don't quite reach around my ear.
