A health writer has stressed the importance of handling contact lenses responsibly.
In an article for Canadian publication Divine, Martha Li warned people not to wear their contact lenses for longer than they are supposed to.
She explained that this is unwise even if the contact lenses feel all right for the wearer.
Contact lenses also need to be thoroughly cleaned and should not be worn on irritated eyes.
Other tips she gave for eye care included eating foods that are high in zeaxanthin and lutein, such as carrots and dark green vegetables.
Smoking can also deprive the eye of oxygen by harming blood vessels.
Recently, Scarborough Today reported that research by Transitions Optical has found that 43 per cent of Britons do not realise that poor nutrition can affect eyes.
Health writer Susan Stephenson suggested eating omega-3 fish oils to help keep blood vessels in the eyes healthy and also highlighted the importance of vitamins A, C and E.
