I found a few styles from O4L that are quite similar and can get them
with tinting.

Those are just a few, in fact I found quite a few that looked very
similar. So take a look around their selection of glasses (especially
in the alloy-eyeglasses section).
P.S. The zenni links are not working at the moment for some reason.
