Dry eye, blinking, and blepharospasm.
The primary purpose of the eyelids is to ensure corneal integrity. An important component of this protective function is maintaining the corneal tear film. Blink characteristics can determine tear film stability. Increasing blink amplitude thickens the lipid layer that overlies the aqueous layer of the tear film. This thickening reduces evaporation of the aqueous layer. Because each blink refor...
متن کاملEEG Eye-Blinking Artefacts Power Spectrum Analysis
Artefacts are noises introduced to the electroencephalogram’s (EEG) signal by not central nervous system (CNS) sources of electric fields inside and outside subject’s body. The artefacts impede the analysis of the signal and should be handled properly. The most common and characteristic kind of artefacts is the electrooculographic (EOG) ones, especially subject’s eye-blinking artefacts. In this...
متن کاملA Human Blinking ‘eye-on-a-chip’
This paper describes a human blinking eye-on-a-chip microdevice that reconstitutes the ocular surface in the human eye. To recapitulate the structural complexity of the ocular surface, we micro-patterned human cells derived from the cornea and conjunctiva on dome-shaped three-dimensional (3D) scaffolds in in vivo-like spatial arrangements. Moreover, this system was integrated with electromechan...
متن کاملReading between Eye Saccades
BACKGROUND Skilled adult readers, in contrast to beginners, show no or little increase in reading latencies as a function of the number of letters in words up to seven letters. The information extraction strategy underlying such efficiency in word identification is still largely unknown, and methods that allow tracking of the letter information extraction through time between eye saccades are n...
متن کاملAutomatic Recognition of Eye Blinking in Spontaneously Occurring Behavior
Previous research in automatic facial expression recognition has been limited to recognition of gross expression categories (e.g., joy or anger) in posed facial behavior under well-controlled conditions (e.g., frontal pose and minimal out-of-plane head motion). We have developed a system that detects a discrete and important facial action (e.g., eye blinking) in spontaneously occurring facial b...
