The last time I had a vet checkup, my veterinarian said that my lil' guy had retained eyecaps. He just had a perfect shed a few weeks ago(one rolled up tube and all) and the "wrinkles" still appear to be there. But that's all they appear to be - just wrinkles on the surface of what I'm assuming is a protective barrier to each eye.
