This seems like a pretty obvious answer but we’ve had many patients wear their lenses too long and get infections.
We recommend following the manufacturers guidelines and regularly replace and clean the contacts as instructed. Also adhere to the rule to immediately remove the contacts at the first hint of redness or discomfort. Over time the contact lenses will collect debris that will impact comfort and vision and which cannot be removed by cleaners. Serious vision threatening infections can result from poor contact lens hygiene and contact lens over-wear.
