Images depicting each of the masks used in repeat simulations, spread of droplets, and droplets within the inside of the masks visualized with ultraviolet light. With the properly positioned cloth mask (A1), the examiner had spread of droplets onto gloves (A2). Droplets spread beyond the outer borders of the mask (A3). With the improperly positioned surgical mask (B1), the examiner had droplets on the gloves, arm, chest, and shoulders (B2). Droplets spread beyond the outer borders of the mask (B3). With a properly positioned surgical mask (C1), the examiner was clear of droplets, but droplets were detected on the side bar of the slit lamp (C2). No droplets spread beyond the outer borders of the mask (C3). With a properly positioned N95 mask (D1), no droplets were detected on examiner or the slit lamp (D2). No droplets spread beyond the outer borders of the mask (D3).
