People who wear reusable contact lenses are nearly four times more likely to develop a rare eye infection that could rob them of their sight, a study has found.

The British scientists behind the research also warned that wearing lenses in the shower, swimming pools and while sleeping raised the risk too.

In the study, they looked at more than 200 daily or reusable contact lens users who came to clinics with either an eye infection or another illness.

They found Acanthamoeba keratitis (AK) — which inflames the surface of the eye and can lead to blindness — was far more common among those who popped the same lenses into and out of their eyes.

The infection is triggered when the micro-organisms get onto contact lenses via a contaminated solution or dirty hands, and then enter the eye through tiny tears. 

Patients suffer eye pain, redness, blurred vision, a cloudy look to the eye and, in severe cases, may end up losing their sight. Treatment includes antiseptics that must be placed directly onto the surface of the eye, possibly for six months to a year.

Acanthamoeba keratitis: The eye infection that could leave you blind

What is Acanthamoeba keratitis (AK)?

This is an infection of the cornea, or surface of the eye, caused by a micro-organism.

How do I catch the disease?

It is most common among contact lens wearers, but can infect anyone.

The illness is triggered when the micro-organism gets into your eye either via placing contact lenses into your eye with dirty hands, or when in the shower or swimming pool while wearing the lenses. 

It then gets into the eye via tiny tears in the surface, and triggers the infection.

What are the symptoms?

 Symptoms include blurred vision, a cloudy or dirty looking cornea, eye pain, eye redness, and watery eyes. 

These can take several days to weeks to appear following infection.

Does it risk my vision?

If left untreated, the infection can lead to permanent vision loss and total blindness, the CDC says.

Other complications include inflammation of the eye that is painful, and partialy vision loss. 

What is the treatment? 

Patients are normally offered an antiseptic to help clear the infection from the eye, which is
