Wearing contact lenses is generally safe, but complications can occur.
As many as 45 million people in the US wear contact lenses to improve their vision. Contacts are generally safe, but several serious complications can occur, especially if proper care is not taken.
It is very important to have good contact lens hygiene. This includes not sleeping, showering, or swimming while wearing contacts to reduce risk of serious complications. The risk of infectious keratitis can be reduced by using daily disposable contacts.
Complications from contacts can have a wide range of symptoms. Talk to an eye doctor if any of the following symptoms occur, as they may be signs of a serious complication: redness or irritation, eye pain, sensitivity to light, blurry or worsening vision, excessive tearing, or discharge.
