“…Their study also has shorter duration of near task compared to the present study. Even though 20 min of near task in the present study seem longer compared to previous studies, [2][3][4]8 it is still considered short compared to a study by Teoh et al 5 where subjects had 2 h of VDU tasks. The difference in their subjects' mean NIBUT was 3.71 s. It is possible that the short duration task in this study had resulted in the relatively small difference of preand post-task NIBUT (mean difference = 1.20 s, preclear NIBUT = 6.59 and post -CLEAR NIBUT = 5.39 s).…”

BackgroundReading from tablets is fundamental to modern culture. This study measured differences in the blink rate and symptoms of ocular discomfort in healthy participants during reading from a tablet and a paper book.MethodsForty healthy, normal males subjects were recruited for this study. Subjects were video recorded during reading a text presented on an electronic device (9.7 inch tablet) and a hard copy format, for 15 min. Ocular discomfort experienced during reading was scored using a visual analog scale. Each participant was examined performing one of the two tasks (randomized) on one visit and the other on a separate visit (crossover design). All subjects were evaluated before the reading tasks and every 5 min during 15 min of reading.ResultsThe mean ± standard deviation blink rate was 19.74 ± 9.12/min at baseline. The blink rate decreased significantly under both reading conditions (to 11.35 ± 10.20 and 14.93 ± 10.90/min when reading from a book and a tablet, respectively). There was no significant difference in the blink rate over 15 min during either type of reading. The mean discomfort symptom scores were 148 for the book and 134 for the tablet; both were significantly higher than baseline. A gradual increase in symptoms was found every 5 min during both types of reading.ConclusionThe study confirmed that both the blink rate and ocular discomfort symptoms were strongly affected during performance of close visual tasks. Both reading conditions affected blinking; this may interfere with tear film dynamics. Such effects were reflected in the immediate development of ocular symptoms, which increased significantly during both types of reading.

“…Eye problems, constituting a widespread but largely unknown epidemic among computer users, are the most common symptoms [25-30]. Dry eye is a common cause of, or is at least associated with, greater asthenopia symptoms among VDT workers [31-35]. Clinical observations have long suggested that VDT users may be at increased risk of developing dry eye disease [2,15,36], and epidemiologic data evidence the magnitude of the problem [36-38].…”

BackgroundA Web-based self-check system including a brief questionnaire would seem to be a suitable tool for rapid disease screening.ObjectiveThe purpose of this preliminary study was to test a Web-based self-screening questionnaire for drawing attention to dry eye disease among general Internet users and identifying those with a higher risk of developing the condition.MethodsA survey website was launched and used to recruit participants from general Internet users. In the first phase, volunteers were asked to complete a Web-based self-screening questionnaire containing 12 questions on dry eye symptoms. The second phase focused on the respondents who reported five or more dry eye symptoms and expressed their intention to seek medical attention. These participants performed the Schirmer test, for evaluating tear production, and completed a paper-based lifestyle questionnaire to provide relevant background data.ResultsOf the 1689 visitors to the website, 980 (58.0%) volunteers completed the Web-based self-screening questionnaire. Among these, 355 (36.2%) respondents reported five or more dry eye symptoms. Then, 99 (27.9%) of the symptomatic participants performed the Schirmer test and completed the paper-based lifestyle questionnaire. Out of these, 32 (32.2%) had abnormal tear production (≤5 mm).ConclusionsThe proposed Web-based self-screening questionnaire seems to be a promising tool for raising awareness of dry eye disease among general Internet users and identifying those with a higher risk of developing the condition, although further research is needed to validate its effectiveness.

The Effect of Antireflection Film Use on Blink Rate and Asthenopic Symptoms during Visual Display Terminal Work

Abstract: Visual display terminal work appears to be associated with asthenopic symptoms and decreased blink rates. The use of AR films on computer displays may prevent both reflections of light from screen surfaces and reduction in blink rates resulting in fewer asthenopic symptoms.
