Standalone device for rapid assessment of critical flicker frequency (CFF)

Bogachyov K., Pavlova M.

People receive about 90% of the information through vision. Both professional work and work on computers at home result in increased visual load. All these aspects lead to significant visual fatigue which is accompanied by various abnormalities, e.g., computer vision syndrome (CVS). This research is aimed at studying the dynamics of fatigue, monitoring of condition and detection of early stages of visual fatigue. Various methods that allow quick assessment of user's visual system efficiency are in most demand. The techniques that are able to provide an express-assessment of the visual system state and give some recommendations for correction of visually-intense work mode are particularly popular.
