Contact lens wearers have been given some top tips to ensure they maintain the health of their eyes.
New York ophthalmologist Dr Marc Werner told Fox News how contact lens wearers should be looking after their peepers.
You should never wear your contact lenses for longer than the recommended amount of time, Dr Werner said.
This is because the cornea of the eye has no blood vessels, therefore it gets oxygen from the air. When you use a contact lens, it puts a barrier up, stopping the cornea getting to the air.
"The longer you keep your lenses in without taking them out and giving the cornea a break, the more problems you will have," Dr Werner warned.
Recently, David Wright, chief executive of the International Glaucoma Association, said a set of quality standards recently introduced by the National Institute for Health and Clinical Excellence will help maintain high levels of eye care within the UK.
