What Causes Eye Infections From Contact Lenses?

Despite correct contact lens cleaning routines, developing an eye infection is always possible. Some of the causes are:

  • Bacteria or viruses (having a cold, for example, can lead to adeno virus eye infection)
  • Sleeping in your contact lenses
  • Using extended-wear lenses
  • Reusing contact lens solution or not keeping contact lens cases clean

Cleaning your contact lenses correctly is necessary to keep your eyes healthy. However, if not done properly, it will create an environment for growing germs like bacteria, viruses, fungi, or parasites on the lenses, and these germs can cause eye infections.

What Are The Risks Of Contact Lens-Related Eye Infections?

Because the contact lens sits on your cornea, the most common contact lens-related eye infection is keratitis, or infection of the cornea.

When severe enough, the cornea can develop a scar, impairing your vision, and sometimes a cornea transplant is necessary.
