What is Mask Associated Dry Eye?

While the use of face masks is essential in the fight against COVID-19, there is a rise in reports of dry, uncomfortable eyes (CORE, Centre for Ocular Research and Education). Masks significantly reduce the outward spread of air. However, exhaled air still needs to disperse; when a mask sits loosely against the face the likely route is upwards. This forces a stream of air over the surface of the eye, creating conditions that accelerate tear film evaporation, leading to dry spots on the ocular surface and discomfort. 

Tips for Patients

1. Ensure that a mask is worn appropriately, particularly with spectacles or sunglasses. A carefully tapered top edge that does not interfere with blinking may help. 
2. Apply lubricating drops; ask your optometrist for personalized recommendations at your next appointment.
3. Limit time in air-conditioned environments and take regular breaks from digital devices.
