COLOR ME UNSURPRISED: CDC: Wearing contacts during sleep may risk serious eye damage.

A 59-year-old man was in the shower, wiping his eyes with a towel, when he heard a popping sound and felt pain shoot through his left eye.

His cornea had developed a severe ulcer and ruptured, tearing a hole in his eye. The ulcer grew from a bacterial infection the man developed after leaving his soft contact lenses in overnight during a two-day hunting trip, according to a U.S. Centers for Disease Control and Prevention case report.

Ugh. Be careful out there.
