Contact lenses have made life easier for a lot of people. For one they are far more comfortable to wear than glasses, especially if you are suffering from high myopia. However, not many of us treat our contact lenses with the high level of care and hygiene that they require. It is important to remember that while they may have given you the blue eyes that you have always craved, they are more than just cosmetic devices.
Eye infections
Improper usage and care of contact lenses can give you some serious eye infections. The most common infection that contact lens wearer suffer from is keratitis, that affects the cornea. In very severe cases, it leads to corneal scarring and impaired vision that ultimately requires a corneal transplant.
Amoebic keratitis
This rare infection is caused by microorganisms found in tap water, swimming pools and hot tubs. This is one of the reasons why you should never wash with or store your contact lenses in tap water. This infection can become very serious. Ophthalmologists recommend that you always rub and rinse your lenses before storing them even if the solution is a “no-rub” one.
Bacterial keratitis
This infection is often cause by bacteria found in soil, water, sewage and plants. This is often transmitted through dirty hands so make sure that you have disinfected your hands thoroughly before you touch your lenses. Also, never, ever “top off” your old solution with a bit of new in your lens case. Throw away the old solution and use fresh solution for storage.
Fungal keratitis
This serious infection is very painful. This infection is very difficult to treat and is caused by fungal microorganisms often found in soil, water and organic matter. Sometimes fungal keratitis could also be caused by contaminated contact lens solution. In 2006, there was an outbreak of fungal keratitis caused by contaminated contact lens solution. Early treatment of fungal keratitis can prevent permanent damage to the eyes.
Corneal ulcer
This is a sore on the outermost layer of the cornea and is one of the most serious eye infections. This could be caused when you sleep with your contact lenses causing eye irritation and scratches on your cornea. Do remember to always rinse your lens case with fresh solution and let it air dry. Replace you case every three months and never wear lenses beyond their expiry.
Symptoms
If you are suffering from blurred vision, redness of the eyes, pain, excessive tearing or discharge, light sensitivity or eye irritation you could be having an eye infection. Do consult an ophthalmologist urgently because these infections can also cause blindness.
