Those are actually cybernetic ocular implants fused into his nervous system that can read visual information and transmit it to his brain in the same manner as his organic eyes. They’re meant to allow him to maintain his vision even when he transforms into organic forms that would inhibit the regular function of his eyes. I ripped off… er… was inspired by the idea of Kim SÃ¼skind from Planetary who used similar goggles to allow her to still see while invisible.
Hm, neat. Still looks creepy, though.
