I've turned into a werewolf and originally had all white eyes. After, for a while, I had the silver eyes but they were very pale due to my original color. I was using the TFC console command to look at my charater and found that my character's eyes a very glitchy. The graphics and detail is all distorted. I loaded, it's still there. I'd mainly like to report this bug to the guys at bethesda. Hoping for a patch coming soon to fix some of these things!

Update: I restarted Skyrim -- it fixed the glitch. Just incase anyone runs into the same problem I did.

i think eye color bugs are alt-tab related, i have them in human form too
