Prolonged facemask use worsened dry eye for hospital workers. Properly fitted masks with nose wires can reduce eye irritation and improve ocular surface health.
Area of Science:
- Ophthalmology
- Occupational Health
- Public Health
Background:
- Prolonged facemask use may exacerbate dry eye symptoms in essential workers.
- A mixed-methods study investigated the impact of facemasks on ocular surface health and dry eye in hospital staff.
Purpose of the Study:
- To examine the associations between facemask use, periocular environment, and dry eye symptoms in hospital workers.
- To understand the impact of facemask type and fit on ocular surface disease.
Main Methods:
- Recruited clinical and non-clinical hospital workers reporting dry eye symptoms and prolonged facemask use.
- Assessed symptoms via Dry Eye Questionnaire and Ocular Surface Disease Index (OSDI).
- Measured objective signs including corneal staining, tear break-up time (TBUT), meibography, and periocular humidity; conducted interviews for qualitative insights.
Main Results:
- 90% of participants reported worsened dry eye severity due to facemasks.
- Increased periocular humidity from masks did not prevent 66% experiencing increased eye airflow.
- Qualitative data indicated poorly fitted masks, especially around the nose, worsened symptoms.
Conclusions:
- Inadequately fitted facemasks pose discomfort and ocular surface health risks for healthcare providers and patients.
- Wearing a well-fitted facemask with a pliable nose wire can mitigate adverse effects from upward airflow.

Administering Oxygen by Mask
Administering oxygen by mask is a common nursing intervention that provides supplemental oxygen to patients with respiratory distress or chronic lung conditions. This procedure involves delivering oxygen at a specified rate through a face mask connected to an oxygen source.
Equipment
The equipment necessary for this procedure includes:
PPE Use in Healthcare Settings II: Doffing
PPE Use in Healthcare Settings I: Donning
Accessory Structures of the Eye
Transmission-based Precautions II: Airborne and Protective Environment
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...
