Contact lens wearers warned not to sleep in them

A warning has been given to people who try to save time by sleeping in their contact lenses.

In an article by Lorie A Parch for Prevention, which appears on msnbc.com, expert Thomas L Steinemann urged people to take out their contact lenses when they sleep.

Steinemann, an associate professor of ophthalmology for Case Western Reserve University, said that closing one"s eyes for hours over lenses is bad for the oxygen flow to corneas.

While people should remove their contact lenses at night, he said that if they are slept in, it would be safer to wear silicone hydrogel lenses.

A silicone hydrogel contact lens by Johnson & Johnson, Acuvue Oasys for Presbyopia, was the first new multifocal contact lens product from the provider in 11 years.

The firm said that the lenses may be good for people whose eyes are dry but want to wear contacts.
