Smoking "may increase eye infection risk"

There is a higher risk of eye infection if people smoke, according to a new study.

An investigation carried out by specialists at the Department of Ophthalmology and Visual Sciences, at the Case Western Reserve University and University Hospitals Eye Institute, Cleveland, Ohio, said that smoking and substantial lens bacterial bioburden increase the risk of a corneal infiltrative infection in those who wear silicone hydrogel contact lenses.

Of the 127 patients who took part in the study and completed it, 38 experienced a corneal infiltrative event.

"In this study, more than 70 per cent of the total risk of [a corneal infiltrative event] in those with substantial lens bioburden is attributable to this exposure," the study authors noted.

Recent research published in Investigative Ophthalmology & Visual Science, suggested that multifocal contact lens wearers tend to drive slower at night than people who wear other means of vision correction.
