Abstract
The tear film is vital for the normal function of the ocular surface, influencing transparency, optical quality, and defense against the external environment. A functional understanding of the tear film depends on a knowledge of its components and their interactions. Recent data indicate the thickness of the trilaminar tear film to be 35–40 μm, the majority (~30 μm) contributed by a mucous gel situated adjacent to the epithelial surface.1–3 This gel contains mainly secreted mucins, which interact with a variety of other components, including a number of highly glycosylated components of the ocular surface glycocalyx.4–7
