Iridium lens? Somehow a hit and miss thing. Oakley will tell you it's due to sweat. Some people say it's the way you clean it (or whatever you used to clean it). Some had no problem even using them for years. Suggest you just replace them.

As long as it doesn't affect your daily usage you should be fine. If its affecting you directly then just get them replaced. Check with revelstoke directly or order from any optical shops who sell oakleys. Would generally cost at least rm150-200. You can also opt to buy off eBay for a cheaper alternative but you have to accept the risk of buying fakes...there are also 3rd party lens manufacturer like VL selling in eBay. Otherwise let me know which colour are you looking for perhaps I can help since I am indeed planning to pick up a pair of monster dog lens, though I haven't actually decided but I guess most likely would be fire iridium. Check in Oakley website for the replacement lens colour option. I'll be getting directly off from
Oakley.com though.

ouch...that's the sucky part of getting them here...have you picked them up yet? I'm sure you're going to enjoy it...
