Apart from decreased tear production, there are also few dry eye causes. One such cause is the increase in the amount of tear evaporation. Factors that cause increased tear evaporation are:

  • Tears present in the eyes evaporate when they are exposed to various external factors like air, wind, heat etc. Therefore, it leads to a rapid depletion of the lubricant.
  • When you do not blink your eyes for a long period of time, like when you are concentrating on any work, for example, while reading something, driving a vehicle or working at a computer.
  • Other factors like some chronic eye disease, inflammation of the eye or heavy damage etc. can also result in reduced lubrication.
