Figure 1.

(a-c) Image showing common incorrect ways of wearing face masks like the neck–beard configuration, the tickler configuration, and the overshooting masker (i.e., wearing mask with the upper end of it, covering up to the inferior aspect of the eye), respectively. (d) The image shows correct face mask configuration, but with a gap near the nasal bridge (yellow asterisk), which would be a source of aerosol spread during visual field testing. (e) A proper method of wearing face mask with the superior strip of mask pinched down on the nose (red arrow) and adhesive tape covering the entire length of the superior border to prevent aerosol contamination
