Causes of dry feeling eyes

What do drying environments do to your eyes?

Your eye has a natural moisturising shield over its surface called the tear film. This lubricates the eye’s surface and helps to maintain clear vision. It keeps the eye hydrated, washes out dust and debris, and helps to stop any bacteria that may enter the eye from causing infections. However, loss of moisture from the eye can disrupt this protective shield, causing your eyes to feel uncomfortable, dry and irritable.

Are you more susceptible to eye irritations?

There are certain factors that can increase your likelihood of eye irritations:

  • The natural aging process can affect the amount of tears produced
  • Hormonal changes, such as pregnancy or the menopause
  • Certain medications, such as hormone replacement therapy, antihistamines and birth control pills
  • Contact lens wear – including the use of daily disposables and lenses for extended wear
  • Long periods of concentration at a computer screen or reading
