Would have preferred to give these replacement lens 3 1/2 stars.
Love the oakleys but changing lenses is more than tricky....it's a nightmare.....removing a lens isn't too difficult but installing a lens....yikes. Took me one hour to install one lens....I'm now going to tackle the 2nd one. If you think you're going to switch with any frequency, think again....unless you're a lot stronger than I am.
