Abstract:Background. Droplet simulation often requires expensive and inaccessible equipment. Herein, we develop and assess a low-cost droplet simulation model using easily accessible materials, open-source software, and a smartphone-based cobalt blue light. Methods. The simulation model was developed using commercial-grade materials and fluorescein dye. A clear face shield was assessed ten times following a simulated cough using fluorescein dye. A conventional ultraviolet Woods lamp was compared to a smartphone-based c… Show more
“…Our group has previously demonstrated the fluorescein‐illuminating capabilities of a cobalt blue smartphone LCD screen 6,8,9 . However, its use was previously limited by the need for two smartphones: one presenting the cobalt blue screen to the patient's affected eye and a second to capture a photograph.…”

The new "Cobalt Blue Selfie" mode obviates the need for a second smartphone, allowing providers and patients to capture fluorescein-illuminated photographs much like they would obtain a selfie.…”
