During the past several decades, a significant, international research effort has been directed towards understanding the composition and regulation of the preocular tear film. This effort has been motivated by the recognition that the tear film plays a critical role in maintaining corneal and conjunctival integrity, protecting against microbial challenge and preserving visual acuity. I n addition, research has been stimulated by the knowledge that alteration or deficiency of the tear film, which occurs in innumerable individuals throughout the world, may lead to desiccation of the ocular surface, ulceration and perforation of the cornea, an increased incidence of infectious disease and potentially pronounced visual disability and blindness.

To promote further progress in this field of vision research, the Tear Film & Ocular Surface Society (TFOS) was created and incorporated as a non-profit organization. The purpose of this Society is to:

Advance the research, literacy, and educational aspects of the scientific field of the tear film and ocular surface

Organize and coordinate international conferences, meetings, workshops, seminars and events to promote better understanding of the tear film and ocular surface

Stimulate interactions among members, and attract new members with diverse disciplinary interests and expertise (e.g. basic scientists, academic clinicians and industry representatives) into the field of the tear film and ocular surface
