Ocular Allergy/Eye Irritation

Ocular allergy is an inflammatory reaction of the eye surface to particles in the environment and is one of the most common ocular conditions affecting all ages.1

Allergens including seasonal allergic conjunctivitis (SAC) and perennial allergic conjunctivitis (PAC) are the most common forms of ocular allergy. SAC is intermittent in nature and is usually caused by airborne pollens. Signs and symptoms usually occur in the spring and summer. PAC can occur throughout the year with exposure to perennial allergens such as house/dust mites, mould and animal hair.1

Eye irritation occurs when the eyes come into contact with an irritating agent causing the eye to water or redden.

The particles causing this inflammatory response may be a result of environmental factors such as pollution and wind, or external allergens such as dust mites and animal hair.2 Inflammation can be asymptomatic or generate symptoms like:3

  • irritation
  • redness
  • sensitivity to light
  • tearing
  • swelling
  • burning
  • itchiness
