Experts Warn Of Dangers Posed By Decorative Nonprescription Contact Lenses.


HealthDay Share to FacebookShare to Twitter (10/29, Goodwin) reported, "Contact lenses are medical devices regulated by the US Food and Drug Administration (FDA)," and "it is illegal to sell them without a prescription in the United States." However, "Halloween is a time when sales of 'special effects,' 'theatrical' and 'decorative' contact lenses spike." Although "there's nothing wrong with buying decorative contacts from an optometrist...who will make sure the lens fits your eye properly, buying cheap contacts from flea markets, street vendors or beauty supply shops is dangerous, experts warn." If the contacts don't fit or are not cared for in the proper manner, those who wear them may be injured or develop an infection that could possibly lead to blindness.
