What causes dry eyes and what to do

26th Oct 2015

The natural flow of tears provides moisture and comfort to your eyes and your tears are actually a combination of water – for moisture, oils – for lubrication, mucus – for even spreading, and antibodies and proteins for resistance to infection. Tears are secreted by glands around the eye and when there is an imbalance in the tear system you may experience dry eyes.

If you find your tears aren’t lubricating your eye properly you may experience –

  • Pain
  • A gritty sensation
  • Itching
  • Redness
  • Feeling like you have something in your eye
  • Blurry vision

Occasionally someone with dry eyes may find they have tears running down their cheeks, this is due to your eyes not getting enough lubrication and your eyes get flooded by tears to compensate, unfortunately these tears are mostly water and while they will wash debris away they don’t lubricate your eyes properly.
