Blepharitis
Eyelid margin disease is a common and persistent inflammation of the eyelids.

Symptoms include:

  • eye and eyelid irritation
  • itchiness of the eye
  • redness of the eye and/or eyelids
  • foreign body sensation

This condition frequently occurs in people who have a tendency towards oily skin, dandruff or dry eyes. With blepharitis, both the upper and lower eyelids become coated with oily particles and bacteria near the base of the eyelashes. It may cause irritation, itchiness, redness, and stinging or burning of the eye.
Conjunctivitis
Conjuctivitis

Conjunctivitis
Conjunctivitis is most commonly referred to as red or “pink” eye. The conjunctiva, which contains tiny blood vessels, produces mucus to coat and lubricate the surface of your eye. When the conjunctiva becomes irritated or inflamed, the blood vessels become larger and more prominent, making your eye appear red. Conjunctivitis may occur in one or both eyes.

Symptoms of conjunctivitis include:

  • inflammation of the eye
  • increased tearing
  • soreness of the eye
  • foreign body sensation
  • itchiness of the eye
  • hazy or blurred vision due to mucous or pus
  • excess mucous (pus)
  • crusting of eyelashes in the morning

Generally, conjunctivitis is easily treated. However, if symptoms of conjunctivitis persist for an extended period of time after treatment, you should have your eyes examined by your ophthalmologist, as these symptoms may indicate a more serious eye problem. There are several eye diseases that cause red eyes, some of which can lead to blindness unless diagnosed and treated.

Dry Eyes
Normally, the eye constantly bathes itself in tears. By producing tears at a slow and steady rate, the eye stays moist and comfortable. Sometimes people do not produce enough tears or the appropriate quality of tears to keep their eyes healthy and comfortable. This condition is known as dry eye.

The usual symptoms include:

  • stinging or burning eyes
  • scratchiness
  • stringy mucus in or around the eyes
  • excessive eye irritation from smoke or wind
  • excessive tearing
  • discomfort when wearing contact lenses
