What is a tear? It is a mix of water, oils, mucus.

A dry eye makes you feel uncomfortable. You may feel dry eye in certain situations such as on a plane, in an air-conditioned room, while riding a bicycle or after prolonged computer work.

Sometimes dry eye causes tears. This contradiction is called reflex tearing. It occurs due to the reduced amount of moisture in the eye itself and it causes eye irritation. It sends a signal through the nervous system for more moisture in the eye. The body sends more tears to make up for the dryness. The process is similar to when sand enters the eye.


Artificial tears are the most commonly used treatment for dry eye. If the person has chronic dry eye, the drops should be used even on days when they don’t feel dry, otherwise they can easily become dry. Also, it may require a complete lifestyle change.

Risk factors

  • Women – Less tear production is common in women, especially when they have a hormonal change, whether it is pregnancy, the use of birth control pills or menopause.
  • Diet with very low intake of vitamin A – higher intake of carrots, broccoli or fish is required.
  • Wearing contact lenses.
