Contact lens infection is a condition where harmful microorganisms, such as bacteria, fungi, and viruses, infect the eye through contact lenses. If left untreated, contact lens infection may be very painful and, depending on their origin and severity, result in vision loss and even blindness.

The most common infection brought on by contact lenses are corneal infections (keratitis), which affects the transparent dome that covers the pupil and iris in front of the eye. For worse cases, contact lens infection may cause scarring in the cornea. Such severe case may require corneal transplant if it causes total vision loss.


Symproms of contact lens infection may include the following:

  • blurry vision
  • eye pain
  • eye swelling
  • eye redness
  • eye discharge or tears
  • increased light sensitivity
  • eyes burning or itching
  • foreign object perception in the eye


Your ophthalmologist will need to do a complete eye exam in order to identify any eye infections brought on by contact lenses. Never attempt to self-diagnose any eye issue since doing so might impair your vision and postpone receiving necessary care. Also, make sure to bring your lens case to your visit since it can be useful in figuring out what’s wrong with your eyes.


Antibiotic eye drops are often used to treat eye infections. The severity of your illness will determine the kind of drops your doctor will recommend.

Your doctor may recommend extra drugs if you have any issues, such as the development of blood vessels. Also, it could be necessary to quit using contacts until the issue is fixed.

The following actions may be taken to avoid contact lens infection:

  1. Comply with your eye doctor’s recommendations for cleaning and storing your contacts.
  2. ┬áRead and adhere to the instructions on your lens cleaner. Even if you have a “no rub” solution, clean using the “rub and rinse” procedure.
  3. Put on your contacts on the timetable that is advised. After using contacts for the advised period of time, dispose of them.
  4. To ensure that your contacts fit correctly and that your prescription has not altered, get frequent eye checkups.
  5. Unless you have been given specific lenses for nighttime usage, avoid wearing your contacts while you sleep.
