Keep an eye out for eye fatigue symptoms Computer-related vision symptoms such as eye fatigue have s om common causes that should not be ignored. Visual display Termin als (VDTs) cause symptoms such as eyestrain, visual discomfort, and vi sual fatigue (Murata et al., 1996). Detecting the likely diagnosis and tr eating the cause can result in improving performance of the user and low ering the risk of ocular problems (Anshel, 2005). Children may also ex perience the visual symptoms related to… Expand
Computer vision syndrome: A review.
The physiological mechanisms that underlie CVS are not completely understood and further research is required to better understand the physiological mechanisms underlying CVS and symptoms associated with the use of hand-held and stereoscopic displays. Expand

Use of visual display units, used for different purposes in institutions, at workplaces and other recreational areas, have risk of developing computer vision syndrome (CVS), one of the emerging public eye health problems in the world. Expand
Management of digital eye strain
Digital eye strain, an emerging public health issue, is a condition characterised by visual disturbance and/or ocular discomfort related to the use of digital devices and resulting from a range ofExpand
Intentions and behaviors to use oral supplements for computer vision syndrome
We study intentions and behavior associated with use of the oral supplement of the EyeScience Computer Eye Strain formula for computer vision syndrome. Participants (n = 588) completed a survey withExpand
Ocular symptoms associated with digital device use in contact lens and non-contact lens groups.
Key descriptors of digital eye fatigue have been identified and may then be used to help identify and evaluate specific causative, palliative, or ameliorating factors. Expand
Comparison of blinking rate in glasses-wearing and non-glasses-wearing computer vision syndrome patients.
The blinking rate per minute is increased with the increase in usage of computer per hour while those who wear glasses experience increased blinking rate. Expand
Use of digital displays and ocular surface alterations: A review.
Clinicians should adopt a treatment strategy based on a multidirectional approach, with various treatments being applied in conjunction on the effects on induced dryness signs and symptoms. Expand
The effect of trick intervention 20-20-20 on computer vision syndrome incidence in computer workers
The conclusion in this study was that there was a significant effect of trick intervention 20-20-20 on the incidence of computer vision syndrome in respondents. Expand
Is the 3× reading rule appropriate for computer users?
A significant increase in the total post-task symptoms was found after reading at the threshold distance ( T ), compared with 0.5 T and 0.25 T, and a 2× rule may be appropriate, i.e., for sustained comfortable reading, the text size should be at least twice the individual’s visual acuity. Expand
Visual impediments to learning
Cognition, learning, and motor planning are dependent upon accurate encoding of stimuli from the environment. If there is an error in, or an impediment to, sensory perception, higher cognitiveExpand


A preliminary study of the effects of computer glasses on reported VDT user symptoms: a field study
Although much research has been performed on the visual problems associated with VDT usage, little attention has been paid to the cause-effect relationship of the symptoms. Also, studies in this areaExpand
Viewing distance variation and related ophthalmological changes in office activities with and without VDUs.
This experimental study was conducted on 14 volunteer female clerks to measure viewing distance variation and related ophthalmological changes in office activities with (session 1) and withoutExpand

The relative contributions of the nature of VDT displays, workstation design, work-practices and optometric factors are discussed, drawing from the substantial body of literature which now exists on this subject. Expand
[Work efficiency and lighting conditions: an experimental study].
Assessment of working efficiency effects caused by lighting conditions characterized by "according to law" illuminations, yet in presence of high or low luminance ratios in the occupational visual field showed that high luminance ratio conditions show a decrease of the performance, which where not detected with low Luminance ratios conditions.

Short-term effects of workstation exercises on musculoskeletal discomfort and postural changes in seated video display unit workers.
Exercises done by video display unit operators while at a workstation resulted in short-term decreases in both musculoskeletal discomfort and postural immobility, suggesting that workstation exercises may be beneficial. Expand
Vertical Gaze Direction and Postural Adjustment : An Extension of the Heuer Model
The authors provide a consideration of the vergence system and suggest an extension of the original model proposed by H. Heuer, M. Drawer, T. Romer, H. Kroger, and H. Knapp (1991) to explain whyExpand
