“…Since then, studies have documented a prospective dose-eresponse relationship between computer use and visual symptoms (Bergqvist et al, 1992). Recently Daum showed in a series of experiments that visual discomfort was associated with lost productivity (Daum et al, 2004). Surprisingly, visual symptoms as an outcome in field-based office ergonomic interventions have received little attention (Brewer et al, 2006).…”

Objective-Examine the effect of a multi-component office ergonomics intervention on visual symptom reductions.Methods-Office workers were assigned to either a group receiving a highly adjustable chair with office ergonomics training (CWT), a training-only group (TO) or a control group (C). A work environment and health questionnaire was administered 2 and 1 month(s) pre-intervention and 3, 6, and 12 months post-intervention. Multi-level statistical models tested hypotheses.Results-The CWT intervention lowered daily visual symptoms (p < 0.01) post-intervention. The TO group did not significantly differ from the control group. The CWT group differed significantly from the TO group (p = 0.01) post-intervention. Conclusion-Workerswho received a highly adjustable chair and office ergonomics training had reduced visual symptoms and the effect was maintained through twelve months postintervention. The lack of a training-only group effect supports implementing training in conjunction with the highly adjustable chair to reduce visual symptoms.

“…Only Aaras et al (1998Aaras et al ( , 2001 and Horgen et al (2004) report on visual symptom changes resulting from both lighting changes and the use of corrective lenses. In a knowledge economy with growing numbers of workers using computers, visual strain can affect performance and overall workforce productivity (Daum et al, 2004).…”

“…37,38 Computer glasses decreased symptoms in those with computer vision syndrome 37 and have improved worker productivity. 37,39,40 Photosensitive Epilepsy Approximately 5% of patients with epilepsy are photosensitive. Four percent to 8% of the general population is photosensitive without having epilepsy-a phenomenon termed photoparoxysmal responsiveness-with the peak incidence at puberty.…”

“…Various frame styles are available, but the lens is the critical component for the desired effects on the visual system. Although authors 37,39,40 have investigated the effects of the glasses on clinical symptoms and worker productivity, to our knowledge, no one has described the neural mechanism for these effects.…”

Objective: To present the case of 2 adolescent high school student-athletes who developed postconcussion syndrome with protracted and limiting visual complaints that markedly affected academic, social, and athletic activity for a year after the onset of symptoms. Both had significant improvement soon after a unique intervention was administered.Background: A 14-year-old female soccer and softball player sustained 2 concussions in the same week. She had persistent symptoms for a year that affected her grades and precluded athletic participation. A 15-year-old male football player sustained a concussion during an altercation with 2 other male adolescents. He continued to have symptoms 1 year later, with a marked decrease in academic performance and restriction from athletics. Both adolescents reported blurry vision, photophobia, and associated headache as significant components of the postconcussion syndrome.Differential Diagnosis: Concussion, postconcussion syndrome, skull fracture, subdural hematoma, epidural hematoma, second-impact syndrome, and visually sensitive migraine.Treatment: Both patients were advised to obtain computer gaming glasses to use throughout the day. The female patient was diligent in her use of the glasses, with marked lessening of symptoms. The male patient was less accepting of the glasses but did report lessening of symptoms when using the glasses.Uniqueness: We hypothesized that postconcussion syndrome with marked visual complaints would respond to and improve with decreased stimulation of the visual system. This was attempted with the addition of computer gaming glasses. Both adolescent athletes responded well to the filtering of visual stimuli by off-the-shelf computer gaming glasses.Conclusions: Postconcussion syndrome is a persistent condition with a myriad of symptoms. Two young athletes developed postconcussion syndrome with prominent visual symptoms that lasted a year. The addition of computer gaming glasses markedly lessened symptoms in both patients.

“…Furthermore, computer user surveys conducted at work consistently reported that vision and eye problems were the most frequently self-identified health problem (Collins et al, 1991;Smith et al, 1981;Dain et al, 1988). It has been demonstrated that the health effects associated with computer use impact productivity (Daum et al, 2004;DeRango et al, 2003). The use of computers has grown exponentially in the last 25 years.…”

A replicated field intervention study evaluating the impact of a highly adjustable chair and office ergonomics training on visual symptoms

et al. 2012

Objective-Examine the effects of two office ergonomics interventions in reducing visual symptoms at a private sector worksite.Methods-A quasi-experimental study design evaluated the effects of a highly adjustable chair with office ergonomics training intervention (CWT group) and the training only (TO group) compared with no intervention (CO group). Data collection occurred 2 and 1 month(s) preintervention and 2, 6 and 12 months post-intervention. During each data collection period, a work environment and health questionnaire (covariates) and daily health diary (outcomes) were completed. Multilevel statistical models tested hypotheses.Results-Both the training only intervention (p < 0.001) and the chair with training intervention (p = 0.01) reduced visual symptoms after 12 months. Conclusion-The office ergonomics training alone and coupled with a highly adjustable chair reduced visual symptoms. In replicating results from a public sector worksite at a private sector worksite the external validity of the interventions is strengthened, thus broadening its generalizability.
