The human tear film is rapidly established after each blink, and is essential for clear vision and eye health. This paper reviews mathematical models and theories for the human tear film on the ocular surface, with an emphasis on localized flows where the tear film may fail. The models attempt to identify the important physical processes, and their parameters, governing the tear film in health and disease.

Purpose: To investigate the short-term impact of exposure to smoke from vegetation burns on ocular surface symptoms and signs.
Methods: Woody bushfuels were burnt in an enclosed room (Flammability Laboratory, University of Tasmania, Australia) to generate particulate matter and monitored in real time (Dust Trak II). Eighteen participants (aged 20-63 years, 8 males and 10 females) fitted with respirators were seated 1.

Objective: To evaluate the therapeutic efficacy and inflammatory modulatory effects of combined 0.01% atropine eye drops and orthokeratology (OK) lenses in controlling myopia progression among adolescent patients.
Methods: This retrospective study analyzed clinical data from 90 adolescent patients (90 eyes) with myopia treated from April 2021 to June 2023.

Objective: To determine the state of ocular surface and tear film in college students who are users of inhalants, mainly vapers.
Methods: We conducted a descriptive, observational, and cross-sectional study with 62 participants whose sociodemographic characteristics, ocular surface status, tear film and variables related to vaping were evaluated. Individuals with a higher (5-7 times per week of consumption) and lower frequency of vaping (1-4 times per week of consumption) were evaluated.

Purpose: This study aimed to revise data published in the literature on the effects of cataract surgery on tear film characteristics, in relation to personal clinical surgical experience.
Methods: A search was undertaken using PubMed (all years). Search terms included 'cataract surgery', 'phacoemulsification', 'cataract extraction', and 'manual small-incision cataract surgery', combined at first with 'ocular surface' and 'lacrimal film'.
