“…Despite the aforementioned limitations, ours is the first study of these characteristics to analyse the relation between CVS and contact lens use in computer workers, as well as the effect of different lens materials. A notable strength of the study is the use of a recently validated questionnaire to measure CVS, which lends greater rigour to our findings as compared to previous studies of this subject. In those studies, failure to control the workplace temperature and humidity was a limitation, since it could not be known if these were outside the recommended ranges and could be affecting tear stability and, consequently, provoking increased symptoms.…”

“…Questionnaires for assessing visual fatigue and eyestrain associated with office work have been used before (Knave et al, 1985;Rajabi-Vardanjani et al, 2014;Segui et al, 2015). In Knave et al (1985), an extensive set of questions about the frequency and intensity of eye discomfort, together with musculoskeletal symptoms, was distributed to office employees.…”

VERAM, Visual Ergonomics Risk Assessment Method, is a valid, reliable, practical and easy to use risk assessment method for evaluating the visual environment. With this method, the risk factors in the visual environment is detected and interventions can be implemented to reduce the occurrence of symptoms related to poor visual ergonomics among workers in different type of work, not only computer work.A visual environment that causes glare, have to high luminance ratio and/or give too low levels of illuminance can cause eyestrain and musculoskeletal strain for individuals at work. The visual ability and experience of visual blur is significant when the risk for glare is high or the illuminance is insufficient. To increase performance and occupational health, reduce sick leave, a good visual environment is required.

“…Current questionnaires that attempt to assess visual fatigue caused by different factors such as VDT (visual display terminal) [7][8][9][10], dry eye [11][12][13][14][15][16][17][18][19][20], or binocular vision dysfunction [21][22][23][24][25][26][27][28][29][30] are onedimensional and do not assess asthenopia comprehensively. Such questionnaires were used to assess asthenopia in previous studies.…”

Background: There has been no standardized questionnaire and objective criterion for assessing and diagnosing asthenopia so far. This study aimed to design a valid and reliable questionnaire to determine the various causes of asthenopia for use by clinicians and researchers. Methods: We developed a 19-item asthenopia questionnaire (AQ-19) in two phases. In the Design phase, 17 experts, 98 patients with asthenopia and 20 controls participated to generate the item list. We generated a comprehensive 52-item list to create our 1st version. The list included selected items based on a literature review, patient interviews and the Delphi experts method. In the Validation phase, we conducted a pilot test (127 patients and 25 controls) and retest (154 patients and 24 controls) for item reduction and a questionnaire validity assessment. Results: Our initial questionnaire contained 52 symptoms and 2 self-evaluation questions. After item reduction and assessment, we generated a 19-item questionnaire. It included 19 symptom items that were classified into three domains through factor analysis. Cronbach's α for the three subscales of this version were between 0.79 and 0.85, while for the complete questionnaire Cronbach's α was 0.90, with a split-half reliability of 0.80. Factor analysis showed the three components have eigenvalues > 3 and these explained 54.3% of the variance. Conclusions: The AQ-19 has acceptable psychometric properties, making it a valid and reliable tool for ophthalmologists and optometrists to evaluate asthenopia as well as to provide clues to find its causes. It provides three levels of information: (1) Identifies the presence of asthenopia. (2) Differentiates three major causal classifications (ocular-surface, systemic, and vision symptoms). (3) Focuses in on a specific cause. The clinician must still use his or her skills to determine the exact cause. The AQ-19 questionnaire has the potential to be used in clinical trials and outcome research, and most importantly to help clinicians efficiently and effectively diagnose the cause of a patient’s asthenopia.
