How To Combat M.A.D.E. (Mask Associated Dry Eye)

Aside from staying home with minimal to no contact with the outside world, face masks, hand washing, and social distancing remain the key ways to slow and prevent the transmission of COVID-19. The most common complaint I hear from my patients relating to their eyes and the usage of masks has been foggy glasses, but an interesting study recently published by C.O.R.E. (Center For Ocular Research and Education) found an increase in dry eye and ocular irritation in people who wear masks for long periods of time. The reason for this has to do with the mechanics of mask wearing. When a mask is worn, especially when it is worn loosely, air flow from our breath is directed upwards towards our eyes and has the potential to cause the tear film to evaporate and cause dry eyes. This upwards flow of exhaled air  is also what causes glasses to fog. 

So what do we do? The first thing is to make sure your mask fits really well over your nose. Patients have asked me how I function wearing a mask all day vis-a-vis the fogging and I show them that when I have my mask on I wear it high on my nose with the wire on top sealed in such a way that air is not constantly escaping from the top. Other ways to seal the mask are by using a cool adhesive called Nerdwax or actually taping the mask on top. If your eyes feel dry, use a high quality artificial tear 3-4 times a day and make sure you remember to blink!  Lastly, the use of digital devices also contributes to dry eyes so make sure you are taking breaks during the workday.
