Wearing contact lenses may help reduce the damage that the sun can cause to people"s eyes, according to a study.
Research published in the Investigative Ophthalmology and Visual Science journal showed that overexposure to UV radiation can damage the cornea, conjunctiva and lens, and can lead to cataracts, the most common cause of visual impairment around the world.
Researcher Dr Heather Chandler, from Ohio State University"s College of Optometry, commented that adding adequate UV protection to contact lenses may be a practical solution to the problems caused by too much exposure.
"This research will help patients and doctors consider appropriate UV-blocking contact lenses for those who need vision correction, to fill in some of the UV blocking gaps left by more traditional means," she added.
