Watch out this Halloween

It’s costume time! As such, the U.S. Food and Drug Administration warns citizens to be careful about donning decorative contact lenses to change eye color, appear menacing or just get that eye-of-the-tiger look. Unlike corrective lenses, decorative lenses, sometimes called plano, don’t require a prescription and pop up around this time of year in beauty salons, convenience stores and on the Internet. Wearing them can lead to corneal ulcers and abrasion, vision impairment and even blindness. So be careful or else next year your costume could include a mandatory seeing-eye dog.
