Researchers through a recent study have found that wearing contact lenses can disrupt the delicate balance of microorganisms that live naturally on eye's surface.

Study researchers stated that compromising the balance of microorganisms can potentially cause serious infections among some users.

Researchers during the study found that wearing contact lenses on daily basis transfer bacteria from the skin to the eye, which could result in wearers suffering from inflammation and infections.

Study was based on a small sample collected from nine different contact lens users and compared the samples with 11 non-lens wearers.

Scientists carried out a detailed genetic analysis of the samples to identify the complete microbial population living on the eyes and the nearby skin of each participant.

Lead author Maria Gloria Dominguez-Bello, said in a statement that their research clearly shows that putting a foreign object, such as a contact lens, on the eye is not a neutral act.

"These findings should help scientists to better understand the long-standing problem of why contact lens wearers are more prone to eye infections than non-lens wearers".

The British Contact lens Association, which represents the UK industry, said that dirty or dusty contact lenses can cause temporary discomfort or redness. These symptoms usually improve once the lenses are removed, it said.

In more serious infections of the cornea, the transparent membrane covers the front of the eyeball. This infection is very rarer, and affects about four in 10,000 contact lens wearers.

The association said vision loss due to corneal infections associated with contact lenses is even rarer, and affects about six out of 100,000 wearers every year.
