Contact Lens Induced Acute Red Eye (CLARE)

CLARE is an inflammatory reaction of the cornea and conjunctiva (a thin and transparent membrane that covers the sclera, the white part of the eye). This infection is mostly caused by sleeping with contact lenses and is characterized by awaking with red eyes.

What are the Symptoms of CLARE?

CLARE typically presents with specific symptoms that occur after sleeping with contact lenses:

  • Waking up with red eyes
  • Eye irritation and discomfort
  • Inflammatory reaction of the cornea
  • Conjunctival inflammation
  • Mild to moderate eye redness

If you experience pain, sensitivity to light, or decrease in vision, you should see your optometrist immediately as these may indicate a more serious condition.

What Causes CLARE?

CLARE is primarily caused by improper contact lens hygiene and wear patterns. The main cause is sleeping with contact lenses, which reduces oxygen flow to the cornea and creates an environment conducive to inflammatory reactions. This condition typically develops when contact lenses are worn for extended periods without proper removal and cleaning.

How is CLARE Diagnosed?

CLARE is diagnosed through a comprehensive eye examination by an optometrist or ophthalmologist. The diagnosis is typically based on the characteristic presentation of red eyes upon waking after sleeping with contact lenses, combined with a clinical examination of the cornea and conjunctiva to assess the extent of inflammation.

CLARE Treatment

In most cases, no specific treatment is required for CLARE. The recommended approach is to discontinue contact lens wear, which usually remedies the condition naturally. However, if redness or irritation persists after 24 hours, you should see your optometrist for further evaluation.
