Background: Refractive errors are the most frequent form of impaired vision and the second most manageable cause of blindness in the world. Surprisingly, uncorrected refractive errors are accounting for 20% of blindness cases as well as 50% of vision loss cases worldwide. During the year 2000, the international prevalence of myopia and high myopia was calculated to be 22.9 percent and 2.7 percent, correspondingly. Purpose: The purpose of this study was to evaluate the different patterns of refractive error among near workers. Methodology: Cross-sectional study was done on 248 participants through a convenient sampling method from the private sector hospitals. Data was collected during 3-4 months from March 2022 to May 2022 by a modified adapted questionnaire to evaluate the pattern of refractive errors among near workers in Lahore. Results: All the participant's profession was associated with near work. 42.3.% of responders reported myopia,10.9% hyperopia, 14.9% simple myopic astigmatism, 2.4% simple hyperopic astigmatism,7.3% compound hyperopic astigmatism, and 5.6% with mixed astigmatism. Conclusion: Near work is strongly associated with the refractive errors most commonly myopia progression and aggravation but unfortunately, there is little research work done in Pakistan on the relationship between near work and refractive errors further studies needed to be done on this topic.
