The Scary Side Effects of Overwearing Contacts

Simple Contacts

Contact lenses, like all other medical devices, require proper upkeep in order to limit the possibility of complications and other undesirable side effects.

Unlike the majority of your body, your corneas (along with tooth enamel, hair and nails) don’t have blood vessels to supply regular oxygen to them. Instead, they get oxygen directly from the air, so when you wear your contacts longer than the prescribed wear period (or regularly sleep with your lenses in), you restrict the amount of oxygen your eye can take in. Less oxygen means your eyes can become susceptible to a range of health conditions, ranging from mild to severe, including:

  • Keratitis (inflammation of the cornea)
  • Blurred vision
  • Redness in the eyes
  • Contact lens intolerance
  • Eyelid swelling
  • Light sensitivity
  • Eye pain
  • Eye ulcers
  • Infections

Fortunately, through proper upkeep, you can avoid and combat the effects of overwear. Learn more about wear schedules and daily upkeep here.

And, if you find yourself experiencing any of the above conditions, contact your eye doctor immediately.
