Blinking is essential for your eye health. It plays a key role in:

  • clearing debris from your eyes, like small particles from the air, dried tears, and dead cells
  • bringing nutrients and other substances to your eyes that help keep them healthy
  • wetting your eyes, which prevents dry eyes and reduces your risk of problems with your tear film
  • bringing oxygen to your eyes
