Replying to Weird Lines on my Crowbar lens

So i was skiing when i realized that my lens was a little blurry. I figured it was a few fingerprints until i went inside to look at the lens. It is a black irid and on the inside of the lens, there are these very fine, small lines that extend from the very edge of the lens towards the middle of the lens. All of the lines are perfectly straight and all of them are in clusters of 5-10. Has anyone else had this? I figure they may be very tiny cracks from the lens flexing or something. but i know for sure that i have never put stress on them. i got them at camp in the summer and just used them this season. i always put them in the bag and a hard case. Do you think oakley would warranty them?
