DO NOT BUY
"The youtube videos (official smith account) showing how to replace this lens is not helpful at all, there are also no detailed instructions or pictures. I got the old lens out and now I can’t get the new one back in. The replacement lens alone was $90 which is already overpriced and all for nothing. I should’ve listened to the other reviews and gone with a different brand. It’s crazy how they market changing lenses on the slopes, just completely not feasible. At least provide better instructions than a lady talking way too fast and not actually showing us what she’s doing. You’re better off just buying a whole new pair which probably consider a different brand."
