Reasons you should never wear contact lenses in the shower - and definitely not while swimming

If you've been wearing contact lenses for a while, you might find yourself becoming a bit more relaxed with the rules your eye doctor told you to stick to.

But there's a reason they give you this advice - and you might end up seriously regretting your life
choices if you don't follow them.

One of the rules is to take your contact lenses out when you shower or swim.

You might think this one is unnecessarily cautious, but flouting it could result in vision loss caused by an infection known as Acanthamoeba Keratitis - basically, a microscopic organism invading the cornea in your eye.As explained on the Moorfield Eye Hospital NHS website, this infection affects the clear 'window' at the front of the eye and can be incredibly painful.

It's caused by a microscopic organism, called Acanthamoeba, which is common in nature and is usually found in bodies of water (lakes, oceans and rivers) as well as domestic tap water, swimming pools, hot tubs, soil and air.

               Around 85% of cases of the infection have been caused by contact lens wear.

Taking a five-minute shower after your gym class or jumping in the pool on holiday without taking out your lenses could mean that this organism finds its way into your eye.

Failure to disinfect your lenses properly can increase your risk of contracting the disease, which is still very rare.

Moorfields' leaflet on the infection states: "Due to the way that UK domestic water is stored and supplied, incidence of the disease is generally higher in the UK than in other parts of the world."

If you do start to experience blurred vision or are worried about your contact lenses, do consult an eye doctor immediately.

Treatment is usually with anti-septic drops administered every few hours (including through the night) as well as anti-inflammatories and painkillers in particularly bad cases.

Vision loss

"In later stages of the disease, scarring on the front of the cornea, resulting from long-term inflammation, is usually the reason for vision loss," the NHS explains.

"In some patients, scarring can be quite extensive and may need further therapy (e.g. a cornea transplant) to rehabilitate vision once the infection is over.
