1. A survey was conducted of 120 students, teachers, and workers in the Optometry lab of Paramedical College in Saifai, Etawah, India to determine the prevalence of computer vision syndrome (CVS) and its major symptoms. 2. The results found that 63 out of 120 subjects (52.5%) suffered from CVS. The most common symptoms were headache (24%), watery eyes (15%), and neck pain (11%). 3. The highest number of CVS cases (27, or 22.5% of total) were in the 16-20 year old age group, likely due to greater time spent on social media and improper posture while using devices.

AIM/ PURPOSE:
Computer and other visual devices are now an essential part of our daily life. With the increased
use, a very large population is experiencing ocular symptoms such as dry eyes, watery eyes and
redness of the eyes to name a few. The aim and purpose of this survey based study is to determine
the prevalence of computer vision syndrome and to determine the most prominent symptom of
CVS among the students, teachers & workers.
Material & Methods: A prospective study was conducted in the Optometry lab of the Paramedical
College at UPUMS, Saifai, Etawah during the month of December, 2017. 120 subjects including
students, teachers, and workers were consecutively enrolled and were subjected to a
questionnaire and the responses were evaluated to know the prevalence and the major cause of
CVS in those persons.
Results: It was found that out of 120 subjects, 63 (=52.5%) were suffering from CVS and remaining
57 (=47.5%) were normal. The common symptoms included headache, neck pain, blurred vision &
watery eyes were observed. The age group of 16-20 years were having the most (=27, 22.5%)
people with the symptoms of CVS. Most common symptoms were Headache (24%), watery eyes
(15%) and neck pain (11%). while Dry eyes (7%) and blurred vision (6%) were the least
commonly experienced symptoms
Conclusion: Persons who continuously use computer for long hours were found to have more
severe problem of vision.

Abstract
A survey-based study was conducted in Optometry lab in Paramedical college Saifai, Etawah Total
120 subjects reported for the checkup and out of which 63 subjects were suspected for the
symptoms of CVS and remaining 57 were normal i.e. 53% people were suffering from CVS in 120
people.
Based on this data it was found that the age group 16-20 were suffering more from CVS. Out of 120
subjects 55 subjects were of the age group of 16-20 out of which 27 i.e. 22.5% were suffering from
CVS. The Basic reason behind this probably be the people of this age group are more addicted to
visiting social sites and spent more time on social media. Another reason behind this is keeping
wrong posture while using devices which would have led to symptoms of CVS like neck pain,
headache, etc.
Another survey was done based on the data collected from subjects and it was found that the most
prominent symptoms of CVS in this survey were HEADACHE (24%), and other symptoms are
watery eyes (15%) and neck pain (11%) while Dry eyes (7%) and blurred vision (6%) were the least
commonly experienced symptoms.
Introduction
A prospective survey- based study was conducted in the Optometry lab of the Paramedical College at
UPUMS, Saifai, Etawah during the month of December, 2017. 120 consecutive subjects including
students, teachers, and workers were enrolled and were subjected to a questionnaire and the
responses were evaluated to know the prevalence and the major cause of CVS in those persons.
The study subjects were selected randomly at their own will, regardless of age and gender and
regardless of their visual status.
The questionnaire evaluated personal, environmental, ergonomic factor, And physiological response of
computer users.
During evaluation following question were asked from the subjects-
1- Duration of computer use?
2- What is the sitting posture while using the computer?
3- Illumination of computer screen?
4- Illumination of room?
5- The distance between eyes and computer screen?
Methods and Materials
.
On comparison of the above three studies, it was found that due to more advancement in
technology and gadgets like computers, laptops, smart phones as well as prolonged use of
their devices, more people are suffering from ocular disorders. One of the limitation of our
study was the subjects were from different area (urban or rural), not purely representing the
rural subjects.
Discussion
Persons who continuously use computer for long hours were found to have more severe problem
of vision. While diagnosing the near work related problem/CVS, we have to consider all the aspects
like Ocular, Extra-ocular, Ergonomic and work place related modification.
Treatment of CVS involves proper identification of the etiologic factors and correction of visual
errors if existent. Special attention should be paid to ergonomic factors like correct posture in
chair, lighting arrangement, antiglare screen on the computer/laptop, follow 20-20-20 rule and
establishing proper working habits. And require a multidirectional approach combining ocular
therapy (Orthoptic Eye Exercises), Physiotherapy with adjustment of the work station and regular
work breaks may help improve visual and body comfort.

As computer become part of our everyday life, more and more people are experiencing a variety of
ocular symptoms related to computer use. These include eyestrain, redness blurred vision, watery
eyes, dry eyes collectively referred as computer vision syndrome. The aim and purpose of this
survey based study is to determine the prevalence of computer vision syndrome and to determine
the most prominent symptom of CVS among the students, teachers & workers. Also the purpose is
to create awareness against harmful effect of digital device and tell how to protect and prevent our
eyes from such digital devices.
1 - Prefer to use a chair specially designed for
computer use so that it provide necessary
support to back, legs, buttocks and arms.
2- Use the keyboard in such a position that
arm and the wrist are in neutral position.
3- The monitor should be kept in front of
user`s chair so that the head, neck and
body face forward when viewing the screen.
