Experts say masks and patches, even wigs and hats, can make it hard for kids to see when they're out trick or treating.
One thing to remember, some masks allow you to see straight forward but don't give good peripheral vision. So it's important to help your child cross the street.
Some make-up should also be kept away from your eyes. Prevent Blindness American suggests using hypo-allergenic or non-toxic products. If you're using fake eyelashes, stick to manufacturer's instructions on the package. And even though they may look cool, never use non-prescription contact lenses. They're illegal and can cause many problems.
"The cosmetic contact lenses that are very popular around Halloween can be very dangerous. First of all, they are not prescribed by a physician. They're placed on the eye and the oxygen permeability of these lenses, the breath ability, is very, very poor," Ophthalmologist Dr. Paul Rychwalski said.
One more thing to remember to avoid an eye injury, avoid sharp props like a pitch fork.
