Causes of computer vision syndrome health and social care essay

Posted by on Jan 21, 2018 in article | 0 comments

The computer is becoming backbone of todays occupational configurations. They will be the heartbeats of the modern world. Computers are just about everywhere from kitchen to cement mixers, from planes to pockets. Without computer, world does not have any global awareness. It has created a whole new environment. A new lifestyle has been born- no cost, rapid and universal, where persons share their understanding and expertise. Pc has pass on its wings within the nursing job likewise and nurses are no more passive users of computer technology, but are now becoming the innovators, coders and implementers of personal computers. (Suparna.K,et.al., (2005).

Vision is our virtually all precious sense. Our eyes are in constant use every waking minute of every day time. Over 80% of our learning is definitely mediated through our eyes, indicating the important function our vision plays in our daily activities. Vision disturbance is usually a silent enemy that only appears after along period of continued stress.

The National Institute for Occupational Safeness and Well being (NIOSH) reported that pc operators, who watch their Training video Display Terminals, report more eye-related problems than non- Video Screen Terminals office workers and in addition indicated that visual symptoms occur in 75-90% of Video Display Terminals employees with 22% of Video recording Display Terminals staff have musculoskeletal disorders.

A survey of optometrists indicated that 10 million eyesight examinations are each year given in American nation due to visual problems at Training video Display Terminals. This review delineated the series of symptoms which eventually referred to as Computer Vision Syndrome (CVS). This problem frequently occurs when the viewing demand of the duty exceeds the visual talents of the Video Screen Terminals customer. The American Optometric Association defines computer eyesight syndrome as that ‘complex of eye and perspective problems related to near do the job which are knowledge during or related to computer work with’. The symptoms may differ but mostly include eyestrain, headaches, blurred vision (range or near), dry out and irritated eyes, slow refocusing, throat and or backache, light sensitivity and double vision.

Using computers for long hours put repetitive stress and anxiety on body, muscle groups and joints specifically to eyes. Problems related to eyes affect all those who spend a significant time dealing with computers. There are plenty of IT pros who spend most of their time in front of screen are at threat of computer perspective syndrome. The pc technology has its pros and cons, the majority of these issues are linked to health. The increased usage of computers in the workplace has brought about the development of a variety of health concerns. Many individuals who just work at a computer Video Screen Terminal reports a higher level of job related complaints and symptoms including ocular soreness, muscular strain and stress. The amount of discomfort appears to increase with the amount of video display terminal employ. Visual discomfort and related symptoms occurring in Video Display Terminal personnel must be named a growing medical condition. Lutron, (1998).

NEED FOR STUDY:

Computer Vision Syndrome retains the distinction to be called the main occupational hazard of the 21st century. Prevention of injury and illness is obviously, the best approach, but comprehensive health care and safety programs can help lessen corporate sector’s workplace accidents, absenteeism or presenteeism and related bills. A fitness program was made to decrease the symptoms of computer perspective syndrome in software pros. A pre and post-test study was conducted to evaluate the effect of the fitness routine. The study revealed that the fitness program helped to reduce the symptoms of computer vision syndrome in program professionals. Namrata Arora Charpe and Vandana Kaushik, (2009)

According to National Association of Application Firms, (2006) reported that quantity of workers is swiftly growing in information technology (IT) sector. Around one million computer pros are graduating from various courses every year. While 10% of the task force was using pc for their occupational activities in 1980’s, the percentage of users is likely to reach 100 million by the finish of the 21st century.

A National Survey of Doctors of Optometry (NSDO), (1997) reported that more than 14% of the sufferers present with attention or vision related symptoms resulting from Video Display Terminals function. The most typical symptoms are eyestrain, headache, blurred vision, and mild sensitivity, double perspective, and color distortion. Great visual demands of Video how to write a history research paper tutorial Screen Terminals work make many individuals vunerable to the development of eyes and perspective related symptoms.

American Optometric Association (2001) has reported that 90% of computer users had visual problems and 10% possessed musculoskeletal fatigue and in addition stated that there is a rise in employee complaints about computer vision syndrome. Even though 99.99% of the risk factors will be 100% preventable, no concrete efforts are taken to ensure computer workers health.

Majority of population involved in computer related careers, no significant exploration in computer related health problems has been completed in India compared to Western countries. The laptop vision syndromes remain under estimated and poorly understood issue at the task place. The general public, health professionals, the federal government and private industries have to be educated about this computer vision syndrome. Consequently there exists a need to have a comprehensive study about them so as to create consciousness and diminish the chance factors in the industry.

Modern nursing focuses on holistic way. It involves teaching in all respects of overall health. Nurses have the responsibility in this advanced environment of technology to identify the symptoms of Laptop Vision Syndrome and create awareness regarding the management of such concerns among computer professionals.

So, the researcher experienced that it’s one of the duties of the community overall health nurses as a health care professional to start creating awareness among people who are at risk for developing Laptop vision syndrome and in addition believes that today’s study is a stepping natural stone in this direction.

REVIEW OF LITERATURE

Review of literature can be a systematic identification, selection, critical examination and written description of related materials pertaining to the region of study or issue of fascination to expand existing understanding or even to develop new understanding Polit and Hungler,(2006).

The related literature of today’s analysis is organized and offered as follows:

Section-I: Studies linked to incidence and prevalence of Pc vision syndrome.

Section-II: Studies related to risk factors and causes of Computer vision syndrome.

Section-III: Studies related

to signs or symptoms of the computer eyesight syndrome.

Section-IV: Studies linked to Preventive aspects of Computer vision syndrome.

SECTION-I: STUDIES RELATED TO INCIDENCE AND PREVALENCE OF Pc VISION SYNDROME.

Mohamed Mabrouk Abdelaziz, et.al., (2009) conducted a report on the incidence and degree of visual defects among computer system users. In this review, 100 subjects (50 computer users and 50 non laptop users) were taken. Using common Snellen’s chart and Ishihara chart, visible acuity and colour eyesight tests were conducted. When compared to non pc users, the visual acuity of laptop users showed a substantial decrease (P<0.05). The incidence of colour eyesight is higher among pc users than non computer users. It has also revealed that there exists a noteworthy difference between samples with visual defects that use pcs and when in comparison to non laptop users and the period of exposure with (P<0.01).Visible defects are correlated to duration of exposure to the utilization of computers and attention disease. The prolonged make use of computers may cause eye strain which immediate to visual defects.

Banibrata Das and Tirthankar Ghosh, (2010) executed a s study to examine the prevalence of musculoskeletal and visual disorders among the visible display terminal. The analysis was conducted in the different business office premises in Kolkata. After choices of the locations, 100 visual screen terminal (VDT) staff are decided on randomly comprising 50 male and 50 female. An in depth study based on a altered Nordic questionnaire was performed among these visual display terminal employees for analysis period to measure the outcome of epidemiological studies on musculoskeletal disorders. The result of the study was that the Lower back problem is the key problem among visual display terminal workers. The both male and feminine visual display terminal workers also suffered pain in neck, shoulder, fore arm, wrist, elbow and different parts of the top extremities. This review revealed that the feminine visual display terminal staff suffer more discomfort sense than male visual screen terminal staff. In this study, it had been plainly mentioned that the irritation feeling was relatively great among the aged visible display terminal personnel. The prolonged period of work in an uncomfortable posture mainly lead to discomfort feeling among the visual display terminal workers. Another locating of this review was that both male and female visual display terminal employees suffered from visual anxiety due to prolonged period of work and without using of antiglare screen in a monitor. The final outcome of this study was the visible display terminal staff suffered pain generally in the higher extremities and lower backside of the body. In addition they suffered from visual stress and anxiety. Females have a higher discomfort feeling than male visual display terminal workers.

Mohamed Ali .K and Sathiyasekaran B.W.C, (2006) conducted a report on the prevalence of Carpal Tunnel Syndrome among computer system professionals and risk factors. There were 648 topics were selected from 4,276 computer specialists from 21 firms with a simple random sampling method. Carpal Tunnel Syndrome was diagnosed based on clinical features. The prevalence of Carpal Tunnel Syndrome was found to become 13.1% (95% CI 10.5-15.7%). Subjects with over 8 years of computer function, over 12 hrs of work each day and program administrators were at an increased risk for Carpal Tunnel Syndrome (OR 3.3, 4.9 and 2.5 respectively). Flexed or expanded hand position had higher risk for Carpal Tunnel Syndrome. Bigger risk for Carpal Tunnel Syndrome was found with higher exposure to computer work. Ergonomic factors are important in facilitating right positioning of palm while dealing with a computer.

Richa Talwar, et.al., (2009) conducted a study to determine the prevalence of health and wellbeing disorders among computer pros and its association with working environment conditions. The study design was cross sectional. There were 200 computer professionals considered as sample size from Delhi which included software developers, call centre workers, and data access employees. The prevalence of visible problems in the study group was 76% (152/200), and musculoskeletal complications were reported by 76.5% (153/200). The result of the analysis exposed that there is a gradual increase in visual complaints as the quantity of hours spent for working on computers daily improved and the same relation was determined to be true for musculoskeletal problems as well. Visual problems were significantly less in people using antiglare screen and those with enough lighting in the area. Musculoskeletal challenges were found to come to be substantially lesser among those using cushioned seats and soft keypad. A substantial proportion of the computer system pros were found to become having health problems and this denotes that the occupational health and wellbeing of the people employed in the computer field should be emphasized as a field of concern in occupational wellness.

SECTION II: STUDIES LINKED TO RISK FACTORS AND FACTORS BEHIND COMPUTER VISION SYNDROME

Izquierdo JC,et.al., (2007) executed an observational study to recognize the risk factors resulting in the computer eyesight syndrome . Twenty-eight participants answered a validated questionnaire and got their workstations observed. The questionnaire evaluated the personal, environmental, ergonomic elements and physiologic response of laptop users. The distance from the eye to the computers monitor (A), the computers monitor height (B), and visual axis height (C) were measured. The difference between monitor height and visual axis height was calculated and called D. Angles of turn to the computer screen were calculated applying the formula [position=tan-1(D/A)]. Angles were split into two groups individuals with angles of gaze which range from 0 degree to 13.9 degrees were included in Group 1; and participants gazing at angles bigger than 14 degrees were contained in Group 2. Statistical analysis of the evaluated variables was done. The findings of the study revealed that laptop users in both groupings used more tear supplementations (as part of the syndrome) than predicted. This association was statistically significant (p < 0.01). Participants in Group 1 reported more pain than participants in Group 2. Associations between your computer perspective syndrome and various other personal or ergonomic variables were not statistically significant.

Zairina A good. Rahman and Suhaila Sanip, (2011) conducted a report to identify sociodemographic and computer system related predictors for computer system vision syndrome .Computer vision syndrome (CVS) is an eyes and vision concerns related to the actions that experienced with regards to the application of computer. Cross-sectional research and face-to-face interviews and workstation evaluation was done. The locating of this study revealed that 68.1% reported computer eyesight syndrome symptoms. Among the samples, simply 19.3% of the respondents put their laptop on computer desk and 61.9% got at least ten minutes rest while on constant one hour computer function. Multivariate logistic regression examination disclosed that the predictors for laptop vision syndrome were female (OR=2.3), age <27 years old (OR=2.89), employ correction spectacle/lenses (OR=1.91), certainly not taking regular rest (Or perhaps=1.78) and use laptop > 7 hours each day (OR=2.01). plus the study concluded that the utilization of correction lenses and very long duration on continuous laptop do the job predispose a person to acquire computer vision syndrome . Resting their eyes in between continuous computer do the job will be helpful to reduce possibility to get computer vision syndrome.

Rosenfield M, et.al., (2012) conducted a study on ramifications of induced oblique astigmatism on symptoms and studying effectiveness on viewing a screen. The researcher recorded the symptoms of the computer system user after a 10 minutes period of reading from a pc keep an eye on either through the habitual distance refractive correction or with a supplementary of -1.00 or -2.00D oblique cylinder added of these lenses among 12 samples. The length correction condition was repeated to determine the repeatability of the symptom and monitored the samples examining speed accuracy for the time of 10 min trial. The findings of the study revealed that there was no factor in reading charge or the amount of errors between your three astigmatic conditions, but there was a significant change in the median total symptom scores for the 0, 1 and 2D astigmatic conditions being 2.0, 6.5 and 40.0 respectively (p < 0.0001). The coefficient of the full total symptom score was ± 13.46. The study concluded that the occurrence of induced astigmatism manufactured a significant increase in post-task symptoms but did not affect reading rate or the amount of reading problems. The correction of little astigmatic refractive mistakes is significant in optimizing patient comfort and ease during computer operation.

Chu C, et.al., (2011) conducted a report to identify computer vision syndrome indicators are particular to computer system function, or merely a symptom of executing a continuing near-vision task. There are thirty fresh samples those who are visually normal were requested to learn text audibly either from a standalone computer or on a paper at a screening range of fifty centimeter for a constant twenty minutes period. For the two sessions the text were used and the size and contrast were matched. For both situations, the target position and luminance were as well. After the reading sessions were over, the samples were requested to complete the written questionnaire based on their level of visual discomfort in the task time. The result of this study disclosed by discriminating the computer and hardcopy conditions and confirmed that there is a noteworthy dissimilarity in median symptom ratings with consider to blurred eyesight in the work period. (time=147.0; period =0.03) and average symptom rating (time = 102.5; period = 0.04). In both cases, symptoms were elevated when the utilization of computer system. Symptoms when the prolonged pc use was substantially poorer than those reported after hard backup fascination under similar examining situations. The result of this study will help the practitioners to improve visual comfort and proficiency during computer operation.

SECTION III: STUDIES RELATED TO SIGNS AND SYMPTOMS OF COMPUTER VISION SYNDROME.

Ranit Kishore and Ashish Arya (2011) conducted an assessment on studies linked to signs and symptoms of computer vision syndrome. Millions of men and women around the world are employing the computers not only as a business software but as a recreational merchandise aswell. Predictions indicate that completely a lot more than 70% of the working inhabitants will be using computer systems by the entire year 2011. There are also approximately 820 million internet surfers, with an envisioned explosion of users to over one billon in the next few years. This heavy computer employ causes various problems related to eyes. According to the record over 100 million persons in the usa today use computers. More than 50 percent knowledge eyestrain, headaches, blurred vision and other visible symptoms related to sustained make use of the computer the result might be quite

similar for India. This sort of stress on the visual system may also cause body tiredness and reduced efficiency at work. The authors have tied to conclude a number of the major illnesses which might come during normal functioning hours on a laptop with a number of the possible solutions of these problems.

Loh K.Y and Reddy S.C, (2008) conducted a review on the various signs or symptoms linked to the computer perspective syndrome. The invention of laptop and advancement in it has got revolutionized and benefited the society but simultaneously has caused symptoms linked to its usage such as for example ocular sprain, irritation, redness, dryness, blurred perspective and double perspective. This cluster of symptoms is known as computer perspective syndrome which is characterized by the visual symptoms which derive from interaction with computer screen or its environment. Three key mechanisms that bring about computer eyesight syndrome are extraocular device, accommodative mechanism and ocular surface system. The visual effects of the computer such as for example brightness, image resolution, glare and quality all are known factors that contribute to computer vision syndrome. Prevention is the most crucial strategy in managing computer system eyesight syndrome. Modification in the ergonomics of the working environment, patient education and proper eye care are necessary in managing computer perspective syndrome.

Miljanović B, et.al., (2007) conducted a cross sectional analysis on the visible related dry vision syndrome. Four hundred and fifty samples in Women’s Health Analysis and two hundred and forty samples had been taken for this analysis. The supplementary questionnaire involves symptoms of dry eyes in day to day activities and their issues while reading, working with computer, watching tv etc.The consequence of this analysis exposed that 1/3rd of research samples experienced clinically diagnosed dry eyes syndrome or rigorous symptoms and 2/3rd did not. Logistic regression was used to see associations of dry attention syndrome with reported dilemmas with daily actions atlanta divorce attorneys group and grouped guesses employing meta-analysis methods. Out from the samples, eighty five percent completed the additional questionnaire, comprising one hundred and thirty five Women’s Health Study and 55 Physicians’ Health Study participants with dry eye syndrome, and 250 Women’s Health Research and 149 Physicians’ Wellbeing Study participants without dried out vision syndrome. Controlling for time, diabetes, hypertension and various other factors, people that have dry eyesight syndrome were much more likely to report issues with reading ([odds ratio] OR = 3.64, 95% [confidence interval] CI 2.45 to 5.40, P < .0001); carrying out professional work (OR = 3.49, 95% CI 1.72 to 7.09, P= 0.001); using a computer (OR = 3.37, 95% CI 2.11 to 5.38, P < .0001); watching tv (OR = 2.84, 95% CI 1.05 to 7.74, P = .04); driving throughout the day (OR = 2.80, 95% CI 1.58 to 4.96, P < .0001); and driving during the night (OR = 2.20, 95% CI 1.48 to 3.28, P < .0001).

Barar A, et.al., (2007) gathered the info in the ophthalmologic literature from the web.. It was noted that the complex of eyesight and eyesight symptoms occurred due to prolonged use of computer and stress. Listed below are the recurrent problems from the laptop users we.e., blurred distance or near eyesight, neck and backache, dry and irritated eye, eye-strain – asthenopia, headaches, slow refocusing. In most of the designed countries, there are suggestions issued by renowned medical associations in regards to to the definition, the diagnosis, and the methods for the prevention, treatment and periodical control of the symptoms within computer users, together with an extremely detailed ergonomic legislation whereas in developing countries like India, it’s important to rouse the curiosity of ophthalmologist colleagues in understanding and recognition of these symptoms and within their treatment, or at least their improvement, through specific methods or through the cooperation with specialist occupational medicine colleagues.

SECTION IV: – STUDIES LINKED TO PREVENTIVE AREAS OF COMPUTER VISION SYNDROME

Ostrovsky A, et.al., (2012) conducted a report on ramifications of job related tension and burnout on laptop vision syndrome among high tech workers. 106 samples were one of them study. All participants completed self-survey questionnaires including demographics, pc vision syndrome, and satisfaction with work environmental conditions, job-related stress and anxiety and burnout. The finding of this study revealed that there was a significant between-group difference in the strength of computer perspective syndrome, but not in its frequency. Burnout appeared to be a significant contributing issue to the intensity and frequency of laptop vision syndrome plus the analysis showed that burnout is a significant factor in computer perspective syndrome problems among high-tech workers. The study concluded the ergonomic impression to improve health, safety and ease of the working environment among pc users, for better perception of the work environment.

Gangamma.M.P, et.al., (2010) carried out a experimental study on laptop vision syndrome and its management with triphala eye drops and SaptamritaLauha tablets. There have been a hundred and fifty one clients were taken for this study. From this, a hundred and forty one finished the procedure. Forty five patients had been advised to take Triphala eye drops in Group A; Fifty three patients had been advised to consider the Triphala eye drops and also prescribed them to consider internally SaptamritaLauha tablets. Forty three sufferers had been suggested to consider the placebo eye drops in Group 3. The result of the analysis exposed that there is a significant progress with triphala eyesight drops in the pc vision syndrome management and in addition improvement in 48.89, 54.71 and 06.98% clients in groups A, B and C with triphala attention drops and saptamritaLauha tablets.

Richardson.S, (2007) executed a cross sectional study on computer system related upper limp pain and computer perspective syndrome in Malaysia. In this review, there were one hundred and thirty-six computer users were considered as samples who had been the University learners and office staff. A rapid upper limp evaluation for any office method was employed for assessment of work-related overuse syndrome. The frequency of computer vision syndrome was examined by including a 10-stage scoring system for each and every of its distinct symptoms. The consequence of this study disclosed that many were using typical keyboard and mouse with out a few ergonomic improvements. About 50% of them had just a little low back pain as of devoid of an modifiable backrest. Countless users had higher ratings of the wrist and throat recommending raised hazard of increasing occupational overuse syndrome, which needed additional interference. Several (64%) were utilizing refractive corrections but still had high ratings of computer perspective syndrome commonly including attention fatigue, headache and burning sensation. The increase of computer system vision syndrome scores (suggesting extra subjective symptoms) correlated with increase in computer usage spells. The study figured further onsite studies are needed, to follow up this survey to diminish the hazards of developing computer perspective syndrome between young computer users.

Yee.R.W, et.al., (2007) conducted a study in signs or symptoms of computer system users and preventive procedures. The researcher likewise assessed the eye related problems through the scientific tests for prolonged computer users. There were 40 samples taken for this study for three time in a day. The scores have been computed predicated on Ocular Surface Disease Index. The evaluation had been done predicated on the scores. The samples had been requested to enjoy the video games for half an hour and the 4 treatment had been utilized in the random buy i actually.e artificial tears, MEGS, no treatment, artificial tears with MEGS(microenvironment spectacles). After the sessions were above, the samples had been requested to answer the questionnaire. The result of the study exposed that there is a noteworthy association found in the in the index value. The p values were calculated. They were regularly dissimilar in fluorescein and lissamine green discoloration with P>0.05. There is a noteworthy advancements in the scores and TBUT(Tear breakup time) and in addition there was a reliable development of progress in lissamine green staining and in fluorescein staining. The computer users anyone who has ocular complaints should gone for ocular area examination and they were cared for with separation of environmental manipulations, ocular area and artificial tears.

Shirley Telles, et.al., (2006) suggested that the yoga practice appeared to diminish visual anxiety. Dry out eye occurs due to computer vision syndrome. To decrease the visual anxiety, frequent breaks utilization of eye drops were necessary. It is also noted that the visible strain had been low in the yoga practices together with the regular breaks and eye drops. To assess the effect of a combo of yoga practices, randomized handled trial was planned. 291 professional laptop users were randomly designated to two groups, yoga (YG, n = 146) and wait list control (WL, n = 145). Both groups had been assessed at baseline and after sixty times for self-rated visual pain using a standard questionnaire. Of these 60 days the YG group practiced an hour of yoga exercise daily for five days in weekly and the hang on list control group does their regular leisure actions for just one hour daily for once duration. There have been 62 in the yoga exercises group at 60 times and 55 in the hold out list group. The scores for the two groups regarding visual distress have been compared. After 60 times, there was a much less score in the yoga exercises group, however in the wait list group confirmed that there was slightly raised scores. The consequence of the analysis exposed that the visual comfort have been reduced because of the yoga practice, as the group who got no yoga exercises intervention (WL) showed a rise in discomfort towards the end of sixty days.

Blehm C, et.al., (2005) reported that because of prolonged computer use almost all of the persons having ocular symptoms. Below computer perspective syndrome mentioned as combinations of different symptoms like redness, irritation, eyestrain, blurred vision etc and the primary cause is usually ocular and ergonomic. But mostly computer eyesight syndrome occurred because of dry eye and also due to various display characteristics. There is a treatment for computer perspective syndrome needed by combination of different approach i actually.e. joining ocular therapy with adjustment of the workstation. Proper light, anti-glare filter systems; ergonomic positioning of pc monitor and regular do the job breaks help to improve visual comfort. Lubricating eyesight drops and special pc glasses help to relieve ocular surface-related symptoms.

Dainoff. M.J, et.al., (2005) conducted a study in ergonomic on the effect of an interference on eyestrain, musculoskeletal discomfort, psychosocial stress while working on monitors. There were twenty eight female data access operators taken as

sample for this study. Interventions had been given in workstation ergonomic training/training, redesign and corrective lenses. In the pretest, the article remarked that occurrence of musculoskeletal pain were measured the visual problems. After a month of intervention, the acquiring of this study revealed that there was statistically significant in reduction of physical signs such as trigger points, throat and shoulder mobility.

Chatterjee. P.K, et.al., (2005) carried out a comparative double-blind placebo-controlled clinical trial of a organic vision drop (itone) was executed to find out its efficacy and safety in 120 sufferers with computer vision syndrome. Patients using pcs for more than 3 hours continuously per day having symptoms of watering, redness, asthenia, irritation, overseas body sensation and symptoms of conjunctival hyperaemia, corneal filaments and mucus were studied. One hundred and twenty individuals were randomly granted either placebo, tears substitute (tears plus) or itone in similar vials with certain code number and were instructed to put one drop four times daily for 6 weeks. Subjective and objective assessments were done at bi-weekly intervals. In computer vision syndrome both subjective and objective advancements were seen with itone drops. Itone drop was found substantially better than placebo (p<0.01) and almost identical results were observed with tears plus (difference had not been statistically significant). Itone is known as to be always a useful drug in pc vision.

Balci.R and Aghazadeh.F, (1998) conducted a report on impact of video display terminals screen spots on nervousness and action of individual with or without bifocal lenses among conventionally proposed workstations over expanded periods of video screen terminal user. The objective of the study was to locate out obscurity of video screen terminal users with bifocal lenses during a standard workstation raises the criticisms and hazards for tremendously collective trauma disorder and study the consequence of computer screens location for video display terminal users among or unique of bifocal on subjective analysis and performance. There were fourteen samples were used this exploration and two screen positioned at an angle 15 degree and 40 degree underneath straight eyes level. The samples were requested to read the text from the computer monitors and asked them to type in the reverse order for one hour for each meeting. The result of this study uncovered that the bifocal lenses using by man had little anxiety in the shoulders, wrists, neck, shoulders, little tiredness and much less eyestrain. They had superior performance in 40 degrees angle screen in comparison with 15 degrees angle computer screen. The result of the study also uncovered that the samples using bifocal lenses had significantly privileged neck distress and less performance in comparison with nonbifocal samples. The display which is 40 degree angle caused little neck pain in comparison with 15 degree angle display. The general finding of the study was females had not as much physical discomfort, less tiredness, and higher overall performance than males.

SECTION-V: STUDIES LINKED TO Understanding AND PRACTICE OF Computer system VISION SYNDROME

Zakia Toama,et.al., (2012) conducted a study to assess the influence of guideline request on the prevention of Occupational Overuse Syndrome (OOS) for computer system users.
