Contact lenses are a solution for people with impaired vision who don’t like the look or feel of eyeglasses.
But unlike eyeglasses, contact lenses require daily maintenance. Without such TLC, contact lenses can become dirty, which can lead to serious infection.
Physicians typically emphasize the importance of proper contact lens care upon prescribing lenses. That’s because of the link between dirty lenses and infections.
But the Cleveland Clinic notes that such infections are often avoidable.
According to the Cleveland Clinic, roughly 80 to 90 percent of contact lens-related eye infections are bacterial. The bacteria staphylococcus aureus, also known as ‘staph,’ is linked to many cases of contact lens-related eye infections. Staphylococcus aureus bacteria are resistant to common antibiotics, which underscores the importance of cleaning contacts to reduce the risk of infection.
Pseudomonas aeruginosa is another type of bacterial infection that can affect individuals who wear contact lenses. The Cleveland Clinic indicates that this fast-growing infection is possibly the most severe. It can lead to a hole in the cornea and there’s a significant chance of permanent scarring and vision loss.
Poor contact lens hygiene also can lead to fungal infections. Fungi such as aspergillus or fusariam pose a threat to vision and infection can occur if lenses are not properly and routinely cleaned.
The American Academy of Ophthalmology reports that, in addition to bacteria and fungi, various things can cause contact lens-related infections. Those factors include:
The buildup of microbes under the lens
Reusing or topping off contact lens solution
Failure to keep lenses clean
What are the signs of contact lens-related eye infection?
Serious vision loss or blindness can result from contact lens-related infections.
However, less severe symptoms may present themselves before the infection progresses to the point of vision loss.
Unusual redness of the eye
Tearing or discharge from the eye
The feeling that something is in the affected eye
Contact lenses require daily maintenance to prevent infection. More information is available at www.aao.org.
