all oakley lenses change real quick

To change the lenses in the Elevate is actually pretty easy. Not as easy as the Air-Brake, but easy. The more you do it, the faster you get. It will probably take you 10 min (including wiping your finger prints off).

It is a easy change and like Grete said the more you do it the easier it is, wouldn't try to do it for the first time on the lift..
