The ocular lubrication, where the eyelid constantly slides on the curved corneal surface, is
considered as one of primary lubrication systems in bio-tribology. Under reliable lubrication …

This study aims to investigate the reliability and efficacy of maximum fluorescein tear break-
up time (FTBUTmax) in diagnosing dry eye disease (DED). 147 participants were enrolled in …

We propose an alternative to the prevailing framework for modelling tear-film breakup, which
posits a layered structure with a mucus layer next to the cornea and an aqueous layer on …

Mucin polymers in the tear film protect the corneal surface from pathogens and modulate the
tear-film flow characteristics. Recent studies have suggested a relationship between the loss …

Depositing and obtaining a liquid film of uniform thickness is a problem integral to numerous
applications and requires an understanding of capillary leveling, Marangoni flows …

The influence of the shear-thinning properties on tear dynamics is analyzed using 2D
numerical simulations. The simulations were conducted in conditions close to those of the …

Evaporation is a recognized contributor to tear film thinning and tear breakup (TBU).
Recently, a different type of TBU is observed, where TBU happens under or around a thick …

The human tear film (TF) is thin multilayer fluid film that is critical for clear vision and ocular
surface health. Its dynamics are strongly affected by a floating lipid layer and, in health, that …

Tear film thinning, hyperosmolarity, and breakup can cause irritation and damage to the
human eye, and these form an area of active investigation for dry eye syndrome research …

A previous mathematical model has successfully simulated the rapid tear thinning caused by
glob (thicker lipid) in the lipid layer. It captured a fast spreading of polar lipid and a …
