Respiratory droplet is particle with diameter greater than 5µm, while
aerosol are ≤5µm according to the World Health Organisation. However,
infection is not neatly separated into the dichotomy of droplet versus
airborne transmission route.
Modelling and simulation have shown the importance of the conjunctival
mucosa as a route of transmission of disease in blood splashes, droplets
and aerosols containing virus. The limited reports from SARS, COVID-19
and influenza season supports its use. However, HCW do not routinely use
face shield if they consider the procedures to be unlikely to be
associated with potential contamination. They also erroneously believe
that prescription glasses is adequate protection. The issues associated
with eye shield use, may be less of a problem with face shield.
