Abstract
The tear film that coats the ocular surface is the major refractive surface of the visual system [1, 2]. It impacts the quality of the retinal image by changing its homogeneity. The tear film composition changes in different status. The behavior of the tear film is dynamic between each blink; it evenly coats the ocular surface immediately after a blink to form a smooth optical interface; the tear film gradually becomes unstable in an interblink interval; and local thinning or interruption of the tear film will lead to optical distortion and scatter [3]. Nonuniform distribution of the tear film will increase intraocular aberrations and scatter, which affects the visual quality of the eye and often manifests as vision fluctuations or blurred vision in the clinic [4–7].
