Dry eye is a common and often chronic problem. With each blink of the eyelids, tears spread across the front surface of the eye, known as the cornea. Tears provide lubrication, reduce the risk of eye infection, wash away foreign matter in the eye and keep the surface of the eyes smooth and clear. Excess tears in the eyes flow into small drainage ducts in the inner corners of the eyelids, which drain into the back of the nose. Dry eyes can occur when tear production and drainage is not in balance. Allergies or environmental factors can play a role in a person having dry eyes. Exposure to smoke, wind and dry climates can increase tear evaporation resulting in dry eye symptoms.

Symptoms

  • Red eyes
  • Watery eyes
  • Blurry Vision
  • Scratchy or burning eyes

Prevention

You can take the following steps to reduce symptoms of dry eyes:

  • Remember to blink regularly when reading or staring at a computer screen for long periods of time.
  • Increase the humidity in the air at work and at home.
  • Wear sunglasses outdoors particularly those with wraparound frames, to reduce exposure to drying winds and the sun.
  • Wear sunglasses no matter if it is summer or another month, as wind and sun can still be present in any season.
  • Avoiding becoming dehydrated by drinking plenty of water (8 to 10 glasses) each day.
  • Avoid air getting blown in your eyes by directing car heaters away from your face.
  • Avoid environments that are drier than normal, such as deserts, airplanes, and places at high altitudes.
