Non-invasive medical diagnostics demonstrate a propensity for dropletgeneration and should be studied to devise risk mitigation strategies againstthe spread of the SARS-CoV-2 virus. We investigate the air-puff tonometry,which uses a short-timed air-puff to applanate the human eye in a bid to detectthe early onset of glaucoma by measuring the intraocular pressure. The air-puffconsists of a vortex trailed by a high-speed jet. High-speed imaging of the eyeduring a typical tonometry measurement reveals a sequence of events startingwith the interaction between the tear layer and the air puff leading to aninitial sheet ejection. It is immediately followed by the trailing jetapplanating the central corneal section, causing capillary waves to form andinteract with the highly 3D transient expanding sheet. Such interaction withthe capillary waves and the surrounding airfield due to the trailing jet causesthe expanding sheet to undergo bag breakup, finger formation by Rayleigh Taylorinstability and further break up into subsequent droplets by Rayleigh Plateauinstability, which eventually splashes onto nearby objects, potentially formingfomites or aerosols which can lead to infections. The complex spatiotemporalphenomenon is carefully documented by rigorous experiments and corroboratedusing comprehensive theoretical analyses.
