I have another pair of these and got this tint to use in the cloudy winter weather. I'm a guy and have a medium size head and evidently a pretty thin upper nose. These are one of the few styles I can get to sit high enough to be able to see through and not over them while riding a road bike. This is due to the adjustable nose pieces.

 The optics aren't perfect but are more than good enough and the price makes you feel a lot better when they bounce down the road/trail. Highly recommended.
