Esculapio J Services Inst Med Sci Jan ;13(1):22-5.

Objective: The purpose of this study was to evaluate. 1. The importance of visual hygiene in adult myopes. 2. To find out the association of myopia with posture and visual environment. Main outcome measures were to evaluate role of visual hygiene, to evaluate the effects of posture in developing myopia and to evaluate the effects of visual environment in developing myopia. Methods: This was an institutional based cross sectional study conducted at College of Ophthalmology and Allied Vision Sciences in the main OPD of Eye Department, Mayo Hospital, Lahore, during the months of July to September 2016. Total of 100 subjects of both genders aged between 5-15 years, having Myopia of -1D to -5D were included in the study by using nonprobability convenient sampling technique. All the subjects were asked to fill the questionnaire containing questions regarding academic performance with and without spectacles. Data was collected through a self designed questionnaire and analyzed on SPSS software (Version 20.00) and p value was calculated by one sample t-test and ANOVA. Results: A total of 100 subjects were checked having myopia of varying degree (1.00- 5.00diopters).The results showed that there was greater degree of myopia in subjects having poor visual hygiene. The results showed that out of 100 subjects, 98 were into the habit of cleaning their glasses before wearing them. Positive relationship between myopia development and reading distance was found. Those who watched TV on daily basis for 3 hours had myopia in the range of -4.25 to -5.0 D. It was also found that most of the subjects study under bright light. Higher degree of myopia was found in subjects who were also computer users. Positive association between posture and myopia development was also found. Conclusion: The results concludes that poor posture, dim light while studying & excessive use of computer is significantly related to the degradation of naked vision. This data and whole study support the assumption that visual hygiene improvement could be useful in minimizing the myopia development.
