Your appearance won't be the only frightening thing about wearing costume contact lenses this Halloween. Your eyes might look like a lizard's for an evening, but the risk of permanent vision loss may not be worth the temporary thrill.
Contact lenses may appear harmlessly soft and small, but a big chunk of American users are improperly disposing their used lenses and adding to the planet's microplastic problem, Arizona State University researchers found.
