What Causes Dry Eyes?

Dry Eyes is a condition encountered by numerous people. It takes place when the tears formed by the eyes are deficient in moisture, lubrication and additional characteristics that aid in giving proper protection to the eyes. Dry eyes may also be triggered by environmental causes. For example, weather, that is a source of irritation to the eyes, may result in the drying up of tears. Individuals with dry eyes frequently feel uneasiness in varied forms.

Tears are a vital defensive agent for the eyes. They not only help the eyes in getting rid of the dust, but also relieve the eyes from discomfort. In addition, tears also furnish the cornea with oxygen and nutrients, and also assist in averting eye infections. Tears consist of three dissimilar layers. The outer lipid layer comprises an oily film that checks evaporation and keeps the eyes lubricated. The middle layer consisting predominantly of water, moisturizes the eyes and also contains some nutrients and proteins that assist in curbing eye infections. The inner layer is made up of mucus that aids the tear film to spread and remain on the eyes. Every layer is vital for the wellbeing of the eyes.

Causes of Dry Eyes

  • Dry eyes can be triggered by a number of factors.
  • A widespread reason for dry eyes is aging.
  • As individuals grow, the formation of productive tears diminishes.
  • These tears evaporate more rapidly.
  • Women on the verge of menopause particularly encounter dry eye conditions because of an augmentation in hormones.
  • One more aspect is that certain individuals are incapable of producing the required volume of natural tears.
  • This complication frequently results in chronic dry eyes as the individual is not in a position to produce tears and the eyes are inadequately lubricated.
  • Environmental factors can also cause the eyes to dry up.
  • Instances of adverse environmental conditions include dusty air, dry or windy weather, or fumes like cigarette smoke.
  • This is particularly responsible for dry eyes in those who wear contact lens as the lenses suck up lubrication and the tear film.
