The Mole Man is extremely near-sighted due to damage his vision suffered years ago, and his eyes are extremely sensitive to bright light. He is virtually blinded by normal illumination. To counter this, he wears protective glasses (an early version of a nuclear weapons test Range Officer's flash-goggles) that both reduce bright light to levels his weak eyes can tolerate and increase dim light to levels by which he can see. His sense of hearing, smell, and touch are far more sensitive than that of a normal human; these senses are heightened, but not superhuman. He possesses a "radar sense" that supplements his own weak natural vision.
