We've spilled a lot of ink on the Anon M1 and M2 goggles, because they're that good. Here is an update on the M1, with more information on lens options.
UPDATE: With more time in the M2, we can still say that Anon has combined awesome optics with great engineering to create the easiest-to-use interchangeable goggle we've ever tested.
The most difficult conditions to ski in are not due to poor snow conditions, but poor light conditions. The Oakley Airbrake is highly recommended for anyone looking for easy lens-changing ability and outstanding optics.
