A Pilot Study of the Effects of Swimming Goggles on Meibomian Glands.

There was no apparent difference in MG morphology and function between goggle-wearing swimmers and nongoggle-wearing control subjects in this study sample. Although swimming goggles have been documented as having adverse effects on the periorbital tissues, mechanical forces from long-term swimming goggle wear may not impact MG morphology or function. The tarsal plate likely plays a protective role for the MGs from external mechanical friction from swimming goggles.
