A Florida man has ended up blind in one eye after contracting a rare infection from a flesh-eating parasite during a brief snooze.Mike Krumholz, 21, took a 40-minute nap with his contact lenses in on Dec. 19 of last year and woke up with his right eye irritated and inflamed.“My contacts just felt really irritated like they were floating in my eye,” the college student told the Daily Star. “I took them out and there was nothing wrong,”However, the irritation failed to subside and Krumholz visited an optometrist the following day, where he was misdiagnosed with the herpes simplex 1 virus.After a month of continuing irritation and blurred vision, the Floridian went to a hospital, where he was eventually diagnosed with acanthamoeba keratitis following a series of tests.According to the Center for Disease Control and Prevention, the serious infection “is caused by a microscopic, free-living ameba — single-celled living organisms that are usually found in bodies of water, soil, and air.”
