Introduction- Severe Acute Respiratory Syndrome Corona virus-2 (SARS-CoV-2) spread mainly through respiratory droplets and contact routes. Long term use of spectacles may prevent repeated touching and rubbing of the eyes. Aim of the study is to find out the protective effectiveness of the spectacles against COVID-19, if present. Objectives- To know the association between infection with SARSCoV-2 and wearing of spectacles. Materials and methods- In this study, 304 patients of Corona virus disease 2019 (COVID-19) were selected. Their spectacles wearing behaviour were assessed through a questionnaire. Spectacles wearing behaviour of general population were obtained from older studies (for comparison). Data was put in the tabulate form and Chi- Square test was used for statistical analysis. Results- In this study, among the 304 total patients, 58 patients showed the behavior of using spectacles continuously during day time and always on outdoor activities. While the spectacles wearing behaviour is about 40% among general Indian population. The protective effectiveness of the spectacles was found statistically significant (p- value .00113). Conclusion- The present study showed that the occurrence of Covid-19 was less in spectacles wearing population than the population not wearing those. The nasolacrimal duct may be a route of virus transmission from conjunctival sac to the nasopharynx. Keywords- COVID-19, Spectacles, Contact route, Conjunctiva, Nasopharynx

印度北部戴眼镜的人群中2019年日冕病毒病（COVID-19）的风险

简介-严重急性呼吸系统综合症冠状病毒2（SARS-CoV-2）主要通过呼吸道飞沫和接触途径传播。长期使用眼镜可能会防止反复接触和摩擦眼睛。该研究的目的是找出眼镜对COVID-19的防护效果（如果存在）。目的-了解SARSCoV-2感染与戴眼镜之间的关系。材料和方法-在这项研究中，选择了304例2019年的Corona病毒病患者（COVID-19）。他们通过问卷调查了他们的眼镜佩戴行为。一般人群的眼镜佩戴行为是从较早的研究中获得的（用于比较）。数据以表格形式输入，卡方检验用于统计分析。结果-在这项研究中，总共304名患者中，58名患者表现出白天连续使用眼镜的行为，并且经常在户外活动。在印度普通人群中，眼镜的佩戴行为约为40％。发现该眼镜的防护效果在统计学上是显着的（p值.00113）。结论-本研究表明，戴眼镜的人群中Covid-19的发生率低于不戴眼镜的人群。鼻泪管可能是病毒从结膜囊到鼻咽的传播途径。关键字：COVID-19，眼镜，接触途径，结膜，鼻咽 发现该眼镜的防护效果在统计学上是显着的（p值.00113）。结论-本研究表明，戴眼镜的人群中Covid-19的发生率低于不戴眼镜的人群。鼻泪管可能是病毒从结膜囊到鼻咽的传播途径。关键字：COVID-19，眼镜，接触途径，结膜，鼻咽 发现该眼镜的防护效果在统计学上是显着的（p值.00113）。结论-本研究表明，戴眼镜的人群中Covid-19的发生率低于不戴眼镜的人群。鼻泪管可能是病毒从结膜囊到鼻咽的传播途径。关键字：COVID-19，眼镜，接触途径，结膜，鼻咽
