Construction worker Toru Nagasawa, 29, was caught after he went outside a man's apartment building and asked for directions. Nagasawa then punched the victim in the face, saying he did not answer politely enough, police said.
Nagasawa then allegedly followed the victim into his apartment and forced him to take off his contact lenses, a police spokesman said.
"Are you wearing contact lenses now? Put them in my eyes," Nagasawa told the 31-year-old victim, as quoted by the Tokyo Shimbun newspaper.
After Nagasawa's arrest Thursday in Kawasaki, just south of Tokyo, police put on display what they confiscated from his home -- 124 pairs of glasses and 30 pairs of contact lenses of a wide variety.
He reportedly stocked them in plastic bags in his room.
Police did not comment on his motive but Nagasawa reportedly said: "I felt good when I wore the glasses of a friend in my junior high school days. I have ever since been searching for glasses that fit me."
