The Effect of Face Mask Wear on the Ocular Surface and Contact Lens Microbiome.

Mask wear resulted in marginally significant higher corneal staining of left eye samples (0.4±0.6 vs. 0.2±0.4, mask vs. no-mask wear, respectively, P =0.035), but otherwise there was no statistical support for differences between mask and no-mask wear for dry eye and CL symptoms with the OSDI and CLDEQ-8 questionnaires, respectively, or for conjunctival staining in both eyes (Table 1 ).
