Two groups of normal subjects were loaded an experimental visual task, or a calculating and discriminating task, on a CRT display screen under different work speeds and amounts. The colour (red, green and yellow) CFF values of the subjects were measured every 15 min during the task and their accommodative function, represented by the accommodation time, was measured before and after the task. The two groups of subjects showed no significant differences in the pattern of change in the colour CFF… 
Visual Fatigue and Performances for the 40-min Mixed Visual Work witha Projected Screen
Objective: The main purpose of this study is to evaluate the visual angle and ambient illumination effects on visual fatigue and performances while viewing from a projected screen for 40 minutes.
A Comparison of Seven Visual Fatigue Assessment Techniques In Three Data-Acquisition VDT Tasks
The results indicated that sensitivities of accommodation power, visual acuity, and CFF were greatly improved by a longer task period, but these 3 measurement techniques did not distinguish among tasks.
Flicker Test as a Load Measurement During the Combined Effect of Heat and Noise.
The results suggest that CFF can be treated as a psychophysical load indicator and changes in physiological and psychological human functions under the combined influence of heat, noise, and physical activity are determined.
An ergonomic evaluation of lens accommodation related to visual circumstances.
This study is intended to make clear the relationships between a number of external conditions, dynamic responsiveness of the lens accommodation, and microfluctuation and the effects of ageing and the difference between monocular and binocular observations are examined.
The Influence of Gender and Age on the Visual Codes Working Memory and the Display Duration - A Case Study of Fencers
Evidence showed that the duration time of display affected the corrective rate of the visual codes working memory, and female fencers' CFF ratios were higher than the male fencers'.
Effects of Display Type, Student Population, and Environment on Reading Performance of Mobile Devices
This study investigated the effects of display type, student population, and environment on search time, accuracy, workload, change of critical fusion frequency (CFF), and subjective visual fatigue
Investigation of Chinese text entry performance for mobile display interfaces
It is recommended to use a touch panel with vertical phonetic arrangement in sending Chinese text messages and mobile display manufacturers can use the results of this study as a reference for future keyboard design.
Evaluation of stereoscopic visual fatigue in experts
The method proposed is reasonably insusceptible to different viewer groups, and the results of repeated experiments are consistent, indicating that it is a promising approach to evaluate visual fatigue efficiently and objectively.


Eye-strain and changes in accommodation of the eye and in visual evoked potential following quantified visual load.
The results showed that the relaxation time in accommodation lengthened and the latency of the positive wave appearing at about 100 ms in VEP increased with the increase in visual load.
The effects of task performance on ocular accommodation and perceived size.
Two studies were conducted to test the hypothesis that performance of cognitive tasks tends to induce outward shifts in ocular accommodation that, in turn, result in changes in perceived size. In the
Influence of VDT (visual display terminals) work on eye accommodation.
Experiments showed that visual tasks in VDT work might induce temporary effects in the visual accommodation system, and changes in the accommodative function were found with statistical significance in the smaller-size character group but tended to deteriorate in the larger- size character group.
[Effects of visual and mental strain on VDT (visual display terminal) performance].
The progression of visual and mental strain in VDT work was investigated through an experimentally-designed VDT task providing a number of stressors including pacing, repetition, judgment and output decisions to measure the effects of CFF, TAF, EEG, and near-point accommodation of various changes in the duration of the testing period.
Age, degraded viewing environments, and the speed of accommodation.
Results indicated that the time to accommodate from a near to infinity target varied as a function of age, room illumination, and the distance of the near-reading task; however, during degraded viewing conditions, the accommodation time for older subjects increased as much as tenfold.
Objective evaluation of eye strain using measurements of accommodative oscillation.
The results suggest that measurement of changes in accommodative oscillation, particularly the low-frequency component (0 to 15 Hz), may provide an objective parameter of eye strain.
Effects of Repetitive Tasks with Different Degrees of Difficulty on Critical Fusion Frequency (CFF) and Subjective State
Abstract Critical Fusion Frequency (CFF) and subjective state assessed by questionnaires were determined on 18 subjects during three different types of repetitive tasks of three hours duration. The
Reaction and Response Times for Accommodation
Abstract Using an infra‐red dynamic optometer, a qualitative comparison of the accommodation responses of two observers to step changes in target position showed marked differences in their ability
A study of thresholds of critical flicker fusion frequency (C.F.) of a light stimulus in patients suffering from multiple sclerosis and the relation between C.F. and visual acuity and the visual fields in multiple sclerosis is also of considerable interest.
