The warning is contained in a new report from the U.S. Centres for Disease Control and Prevention (CDC), which was released at the weekend. The FDA regulates contact lenses as medical devices.
A contact lens is a thin lens placed directly on the surface of the eye. CLs are considered medical devices and can be worn to correct vision, or for cosmetic or therapeutic reasons.
In 2004, it was estimated that 125 million people use CL worldwide. According to the World Health Organisation (WHO), approximately 90 per cent of visually impaired people live in developing countries.
However, considering that globally, 80 per cent of all visual impairment can be prevented or cured, efforts to reduce poor vision are at country and continental levels.
According to the new report, nearly one in five contact lens-related eye infections reported to the U.S. Food and Drug Administration (FDA) over the last decade resulted in eye damage.
The report reviewed 1,075 reported contact lens-related infections between 2005 and 2015. The patients in those injuries said they had a scarred cornea, needed a corneal transplant or suffered a reduction in vision. According to report the CDC said, “More than 10 per cent of the patients sought emergency care…”. The Director of CDC’s Healthy Water Program, Michael Beach said, “Contact lenses are a safe and effective form of vision correction when worn and cared for as recommended. However, improper wear and care of contact lenses can cause eye infections that sometimes lead to serious, long-term damage.” As part of the strategy to prevent damage including poor vision, the CDC further urged contact lens users not to sleep wearing contact lenses. “Always use fresh contact lens solution, and replace lenses often,” the statement added.
