  • Wearing contaminated lenses: parasites, fungi or bacteria can inhabit your contact lens’ surface which results in contaminating your cornea when you wear them, consequently leading infectious keratatits.
  • Viruses: for example herpes viruses and virus that triggers Chlamydia can result keratitis.
