“…A study showed that there is a relation between the symptoms and signs and the time used per day and duration per year of exposure to the computer [4,13,40,41]. Not taking a break between activity is also one of the factors that predispose individuals to develop CVS [42].…”

Nowadays the computer has changed and eased the lives of many people in the workplace. Office work, conducting research, preparation of notes and other computer related works have always involved a range of activities, such as typing, filing, reading, and writing. With the evolution of the computer, all these tasks can now be completed using one device. Desktop, tablets, smart phones and personal computers are some of the visual display units, used for different purposes in institutions, at workplaces and other recreational areas. But apart from their advantage, usage of visual display units have risk of developing computer vision syndrome (CVS) which is one of the emerging public eye health problems in the world. CVS is one of the most important occupational hazard of the 21 st century which affects 70 percent of all computer users [1].The American Optometric Association defines CVS or digital eye strain as a ''group of eye and vision-related problems that result from prolonged computer, tablet, e-reader and cell phone use'' [2].Nearly more than half of the world's populations are using the internet as described by Internet world stats [3]. It is estimated that nearly 60 million people suffer from CVS globally, and that a million new cases occur each year [4]. The most encountered symptoms during computer usage are reduced blink rate, tired eye, headache, neck pain, blurring of vision eye strain [5-8]. It is also stated that the performance of the human vision system is reduced due to long period usage of computer and discomfort lightening conditions [9]. It is also known that blue light emitted from a computer screen can reduce the amount of melatonin [10]. Annoying reflections [11], head position and direction of gaze during performing on visual display units can lead to symptoms of CVS [5].CVS significantly impairs workplace productivity and reduces the quality of life by placing unusual strain on human physical well-being as well as reduce job satisfaction and lost work time [1,12,13]. It is also known that CVS can reduce work accuracy in specific tasks by as much as 40% [1]. Reading from a computer screen can reduce understanding ability compared to reading test on print paper [14], which in turn may affect schooling or work-

“…One of the most prevalent is a collection of vision problems termed computer vision syndrome (CVS). CVS, also known as digital eye strain, encompasses many types of vision issues related to increased screen time, including dry eyes, ocular discomfort and diplopia 21. There is a positive relationship between symptom severity and the duration of exposure to computers.…”

“…There is a positive relationship between symptom severity and the duration of exposure to computers. Symptoms may appear after ≥2 hours of computer screen use 21. CVS is also incredibly common – approximately 40%–90% of adults and 80% of adolescents experience symptoms of CVS during or after screen time 22,23.…”

Historically, visual acuity has been the benchmark for visual function. It is used to measure therapeutic outcomes for vision-related services, products and interventions. Quantitative measurement of suboptimal visual acuity can potentially be corrected optically with proper refraction in some cases, but in many cases of reduced vision there is something else more serious that can potentially impact other aspects of visual function such as contrast sensitivity, color discrimination, peripheral field of view and higher-order visual processing. The measurement of visual acuity typically requires stimuli subject to some degree of standardization or calibration and has thus often been limited to clinical settings. However, we are spending increasing amounts of time interacting with devices that present high-resolution, full color images and video (hereafter, digital media) and can record our responses. Most of these devices can be used to measure visual acuity and other aspects of visual function, not just with targeted testing experiences but from typical device interactions. There is growing evidence that prolonged exposure to digital media can lead to various vision-related issues (eg, computer vision syndrome, dry eye, etc.). Our regular, daily interactions (digital behavior) can also be used to assess our visual function, passively and continuously. This allows us to expand vision health assessment beyond the clinic, to collect vision-related data in the whole range of settings for typical digital behavior from practically any population(s) of interest and to further explore just how our increasingly virtual interactions are affecting our vision. We present a tool that can be easily integrated into digital media to provide insights into our digital behavior.

“…If this syndrome is not resolved immediately, it can hinder daily activities, cause discomfort, increase work errors, reduce worker productivity, and decrease job satisfaction. The effect of eye damage tends to increase as exposure length per day and duration per year increases with the risk of permanent damage and takes years to appear (Mussa, 2016). However, not everyone considers CVS to have serious negative effects, primarily on eye health, due to the long time for CVS severity to take form.…”

Introduction: Computer Vision Syndrome (CVS) or digital eye strain is a collection of eye problems related to vision. The telemarketing division in Bank X has 10 hours working time per day and 60 hours per week. This study aimed to determine CVS complaints among telemarketing workers and analyze the factors that caused CVS complaints in workers. Methods: The study used a cross-sectional study design, with a total sample of 53 workers. The variables studied were lighting intensity, monitor distance, age, refractive disorders, eye rest, and eye protection. The study used a lux meter to measure the light intensity and the Snellen chart to see eye refraction abnormalities. Results: The results determined that 77.4% of computer workers in Bank X Telemarketing division experienced CVS complaints while 22.6% did not experience CVS. The results of statistical tests showed that light intensity, monitor distance, refractive disorders, and eye rest were associated with CVS complaints, while age and eye protection equipment were not related to CVS complaints. Conclusion: Most telemarketing workers experienced CVS complaints caused by lighting intensity, monitor distance, refractive disorders, and eye rest.
