  • Avoid rubbing your eyes: Rubbing can distress the tear film and spread irritants such as dust over the eye surface.
  • Keep your hormones in check: Consult with your Healthcare Provider about the correct hormone medication or treatment for you.
  • Take care of your contact lenses: Keep lenses clean and if possible try not to wear them all the time.
  • Diet and nutrients: Eat 3 healthy and balanced meals every day. If you suffer from Dry Eye Disease consider a diet high in omega-3 fatty acids.
  • Drink plenty of water every day: If your body is dehydrated, the moisture in your eyes can also be depleted.
  • Blink!: Blink your eyes as often as possible, especially when staring at a computer screen or digital device. This will allow the moisture of the tear film to be spread over the eye surface.
