Factory Pilot Eyeshade System

[skibum]

Hello all. I just joined this group so I could hopefully find an answer to this question. I recently bought a box of ski stuff at an auction. Included was an Oakley Factory Pilot Eyeshade system. It has a clear lens in the frame but has three other tinted lenses. One set has small holes in the top of the lens. Is there some trick to changing out the lenses? I don't want to break them. Why three sets of tinted lenses? They also came with some extra pieces that go over your ears. I plan on using them for cross country skiing. Sincerely appreciate any advice or comments.

Nice purchase.

To change the lenses out release the bottom first around the nose piece by pulling it down. The holes are vents so they do not staem up so much when you get active. The othyer lenses are just spares. The the bits are earstems that wrapp behing your ears so they stay on while getting big air!
