Decreasing Contact Lens Infections

Dr. Diane Spada

Contact lenses are very convenient and offer many benefits for many who require corrective eye wear.  While they are safely used by millions worldwide, they do carry a risk of eye infection. An infection of the cornea, or “keratitis”, is most commonly related to poor contact lens handling hygiene and contact lens over-wear. Organisms that can cause or contribute to a keratitis include, but are not limited to, bacteria, viruses, and other microbes.  Some symptoms of contact lens-related infections (including keratitis) may include blurry and fluctuating vision, redness of the eye, excessive tearing, and light sensitivity.  Also, a new awareness of something ‘being in your eye’, what we call a foreign body sensation, can be felt when there is an eye infection.  To decrease the risk of keratitis, ensure that you do not wear your contacts lenses for longer than the period of time approved by the manufacturer, ensure that you use fresh solution to clean and disinfect your lenses, and make sure you practice safe and hygienic handling and storage of your lenses.
