They are a good all-around lens, cheap too. If you can get some persims (dark/overcast days) and some Fire irids (sunny days). You probebly will be blinded on a sunny day. I tested out mine a week ago on a super bright day (not skiing, but I wish!) and I had to skint, not even looking at the sun.
Heres a couple pics to show what the lens really looks like, not the mock-up on oakley.com:
^the good thing is what you see through them is like 95% what it would look like with your naked eye. Oakley says its like 60% or something but Persimmon is basically clear with a light brown coat. Not really, but they look that way.
