People who wear coloured contact lenses that have not been purchased from an official retailer risk putting their eyesight at risk, one healthcare authority has warned.
According to the US regulatory body the Food and Drug Administration (FDA), many people have been attempting to imitate the characters form recent TV series and movies in recent years, which has made coloured contact lenses extra popular.
While this is fine as along as people are purchasing the contacts from a reputable and registered supplier, there is a danger that vision could be compromised if the products are bought from a vendor that does not have the authority to sell them, the FDA notes.
The body adds: "Just like regular contact lenses you should never buy contact lenses from a street vendor, a beauty supply store, or a novelty store and you should always have a prescription."
If people do not see an eyecare professional and get a prescription, then the contact lenses they receive may not fit or work properly, which could damage the eye, the FDA noted.
