Countless adults, teens and even children will be wearing coloured contact lenses this Halloween, but few are aware of the risks involved. Ever wondered what those cat-eye contacts are doing to your eyes? If you got them without a prescription, beware of health complications.
Enjoy a safe and happy Halloween by educating yourself and others about the dangers of wearing coloured contact lenses without a prescription.
Why Can Over-The-Counter Coloured Contact Lenses Cause Eye Damage?
Contact lenses made to change one’s appearance go by many names: cosmetic, theatrical, Halloween, circle, decorative, coloured, or costume contact lenses. While it’s illegal to sell coloured contact lenses without a prescription, authorities rarely enforce the law -- which means they’re still accessible in many places.
Many people believe that wearing non-prescription colour contact lenses can cause no harm. This unfortunate myth has led to many contact lens complications. For instance, when a person feels that a contact lens is “dry”, it could be because the lens is not a good fit. Ideally, the lens should follow the contour of the eye, and stay centered, with enough lens movement to allow tear exchange beneath the lens.
Furthermore, non-medical coloured contact lenses are often produced by unlicensed manufacturers that tend to use inferior plastic and toxic materials, such as lead (often used in lens colouring), which can get absorbed through the eyes into the bloodstream. These illegal lenses may also contain high levels of bacteria from unsanitary packaging, shipping, and storage conditions.
Therefore, purchasing any kind of contact lenses without a prescription or medical oversight can result in a variety of eye complications, such as corneal abrasions, eye sores, conjunctivitis, other eye infections, vision impairment and, in rare cases, even permanent vision loss.
Even if you have perfect vision, all contact lenses, including coloured contacts, require a prescription and proper fitting by an optometrist.
