Results revealed that the addiction percentage among participants was 48%. Bachelor degree students were found to have the highest degree of addiction. 3

Most of the subjects i.e. staff members and students were aware about ocular symptoms due to smart phone use. Unlike students, staff members were more aware of it.
In October 2014, Gen Xers, and Millennials a report from the Vision Council discussed digital device usage by adults 90% spend 4 hours per day, 60% spend more than 5 hours per day and 30% spend more than 9 hours per day. More than 60% report symptoms of digital eyestrain including redness, burning, itchiness, blurred vision, fatigue and headaches.4While staring at screens, we blink less increasing the risk of dry-eye disease. 5 In discussion more than 10 million people suffer from dry eyes in this age of smart phones. 6 Eye strain occurs when the eyes get tired from intense use of cell phone.7 Excessive use of the smart phone at near leads to excessive stimulation of ciliary muscle. It was the first case series to report an association of smart phones and accommodative spasm.8 Use of smart phones may be an emerging cause of unilateral ocular pain and headache.9 A study revealed that children using mobile phones for over 4 hours a day develop squint and double vision.10 The premature development of cataract is closely linked to the increase in cases of eye fatigue or presbyopia, which appears more and more to be the result of longer usage of smartphones.11 Scientists have found the chemical reason that blue lights are bad for the eyes. The blue light from smart phones could also contribute to age-related macular degeneration. The cell death caused by blue light excited-retinal doesn’t usually happen until a person is about 50 or 60 years old, which is when age-related macular degeneration usually sets in.12 Mobile phones have been linked to a rare form of eye cancer. The regular use of cell phones could lead to an increased risk of contracting uveal melanoma, in which tumors form in the layer that makes up the iris and base of the retina.13 Most of the subjects, unlike students are aware of ocular symptoms.
A device used for phone calls and having a highly advanced features, high-resolution touch screen display, Wi-Fi connectivity, and Web browsing capabilities. Subjects who knew about 3 or more ocular symptoms were labeled as aware and below that were labeled as unaware. Low level awareness: If subjects were aware of 3-4 ocular symptoms they were included in the criteria of low level awareness. Moderate level awareness: Subjects aware of 5-6 ocular symptoms were categorized in moderate level awareness. High level awareness: Subjects who were aware about 7 or more ocular symptoms were categorized in high level awareness It is a cross- sectional study, at the Pakistan Institute of Community Ophthalmology (PICO) Hayatabad Peshawar for 6 months and non-probability convenient sampling. After ethical approval, an informed written consent was taken from all the subjects meeting eligibility criteria of the study. Data was collected using a questionnaire for awareness about ocular symptoms caused due to smart phone use. The data was entered and analysed through SPSS software version 17. Inclusion Criteria: All the literate subjects of the Pakistan Institute of Community Ophthalmology present at the time of data collection were included in my study.
Exclusion Criteria: Those who were not willing to participate.
Graph 1: Students Awareness Level The above graph shows that 50% (24 out of 48) students were highly aware, 33% (16 out of 48) were low level aware and 16% (8 out of 48) were moderate level aware about ocular symptoms due to smart phone use.
Graph 2: Symptoms Awareness The above graph shows that 80% subjectswere aware about the eyestrain/fatigue of the eyes due to smart phone usage.
76% subjects were aware about the irritation/burning of the eyes
51% subjects were aware about the ocular pain
46%subjects were aware about the redness of the eyes
45%were aware about the watering of the eyes
42%were aware about the eyesight deterioration
31%were aware about the double vision
8%were aware about the macular degeneration
6%were aware about the cataract
The study “Awareness about ocular symptoms due to smart phone use” aimed to evaluate the awareness about ocular symptoms due to smart phone use. There were many contradictory results reported regarding ocular symptoms due to smart phone use and its awareness. It was found that 82 out of 104 (78%) subjects were aware about ocular symptoms due to smart phone use while 22 (21%) subjects were unaware about it. A survey was conducted named “Influence of smart phone on dry eye syndrome in adolescents” in which they analyzed the relevance association between smart phone usage time and dry eyes in high school students. They conducted question investigation survey of 200 (men 140, women 60) high school students. 182 students who met the appropriate criteria were included in this study. 94 students were diagnosed with dry eye syndrome by Ocular Surface Disease Index (OSDI). In this study, they revealed and observed a meaningful significant correlation between smart phone usage and dry eye syndrome. Therefore, it is important to emphasize control of smart phone usage in adolescents.14 Awareness among professions showed that 89% (34 out of 38) staff members and 72% (48 out of 66) students were aware about ocular symptoms due to smart phone use. In 2014 Jun Hyung Moon carried out a case control study and stated that children using mobile phone was high associated with pediatric Dry Eye Disease.15 The awareness and unawareness among staff members about ocular symptoms due to smart phone use in which 89% (34 out of 38) were aware and 10% (4 out of 38)were unaware about ocular symptoms dueto smart phone. A survey was done in Hong Kong in which anonymous 40 years old was diagnosed with eye cancer and the reason was known to be the usage of his smart phone pattern. There are still doubts about smart phone causing a threatening ocular disease i.e. eye cancer. 16Awareness level among staff members shown in graph 4 showed 50% (17 out of 34) staff members were highly aware, 26% (11 out of 34) were low level aware and 11% (6 out of 34) were moderate level aware aboutocular symptoms due to smart phone use. The awareness among students in which 72% (48 out of 66) students were aware and 27% (18 out of 66) were unaware about ocular symptoms due to smart phone use. Andrew Griffin performed a study on people who were addicted to their smart phones. He found out that it is causing chemical variation of the brain that could lead to severe tiredness and anxiety.1750% (24 out of 48) students were highly aware, 33% (16 out of 48) were low level aware and 16% (8 out of 48) were moderate level aware about ocular symptoms due to smart phone use. A medical director named Jeff Taylor claimed that at least 1 out of every 4 eye patients comes with complain of eyestrain and the commonest reason is using small screen smart phone for reading purpose.18 This study also showed awareness about different ocular symptoms caused due to smart phone use. It showed that most 80% staff members and students were aware about eyestrain/fatigue caused due to smart phone while very few 8% and 6% were aware about smart phone use causing cataract and macular degeneration respectively. A study conducted by Aswitha Priya Sadagopan in 2017 revealed that 43% of the students having symptoms complained of any one of the symptoms of vision syndrome while working on smartphone.19 We also found that 76% of subjects were aware about the irritation/burning of the eyes, 51% subjects were aware about the ocular pain, 46% subjects were aware about the redness of the eyes, 45% were aware about the watering of the eyes, 42% were aware about the eyesight deterioration and 31% were aware about the double vision due to smart phone use. A study in Kocaeli, Turkey concluded that subjects who possessed smart phone for more than 2 years had a significant increase in blurring of vision compared to users having mobile phone for less than 2 years in which female had been reported to have more inflammation in the eyes as compared to men.20
There is a shortage of literature survey to find out the awareness in developing the ocular symptoms due to smart phone use. From this study it is concluded that most of the subjects i.e. staff members and students were aware about ocular symptoms due to smartphone use. Unlike students, staff members were more aware about it. Numerous staff members and students were highly aware while very few were unaware about some of the ocular symptoms caused due to smart phone use.
