Contact Lens Intolerance (CLI)

Do you have symptoms of CLI?

Some people experience the symptoms of CLI a few times a year, while others suffer the symptoms on a daily basis and can no longer wear contact lenses. The level of discomfort people experience can range from mild to severe, with symptoms including:

  • Dryness, itchiness, or scratchiness
  • Redness
  • Irritation
  • Inflammation
  • Pain, stinging, or other discomfort when applying contact lenses
  • Corneal abrasions
  • Corneal ulcers
  • Rationing contact lens time
  • Resorting to glasses

At Carrot LASIK & Eye Center, we encourage you to see us for an evaluation if you are experiencing symptoms of CLI. Symptoms like these should never be ignored. If you have two or more of these symptoms, schedule an appointment to see an eye doctor like the experts at Carrot LASIK & Eye Center to be evaluated.

What is Contact Lens Intolerance (CLI)?

Nearly 41 million Americans rely on contact lenses for temporary vision correction, and many prefer them to glasses. However, wearing contact lenses can result in a common and dangerous side effect known as contact lens intolerance (CLI).

Contact lens intolerance is the term used to describe the point at which the eye can no longer tolerate the foreign body (contact lens) that has been in place, and the eye begins to show signs of rejection. Contact lens wearers suffering from CLI are no longer able to apply a contact lens to their eye or wear contacts for any extended time without pain, discomfort, or injury.

Most contact lens wearers who have common refractive errors, such as nearsightedness, farsightedness, and astigmatism, have experienced some form of contact lens intolerance. Though CLI is common, and rates increase with age, it is often an overlooked issue. It can be especially frustrating for those who rely on their contact lenses for clear vision and don’t want to go back to wearing glasses.
