Risk of Corona virus disease 2019 (COVID-19) among spectacles wearing population of Northern India
Abstract
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.
