Background and objectives: The purpose of our study was to determine the effect and compare the changes between safety goggles and face shields on tear film parameters.
Methods: The total sample size of our project was 60, which were equally distributed between two groups of 30 subjects each, group 1 being safety goggles and group 2 of face shields. Baseline measurement of NITBUT and TMH using tearscope was taken and then subjects of group 1 were asked to wear safety goggles for 1 hour and group 2 subjects were asked to wear face shields for 1 hour and measurements of NITBUT and TMH were taken again.
Results: TMH and NIBUT mean baseline for both eyes were found to be significantly decreased post use of Safety goggles and Face shield from baseline values (p <0.001).TMH and NIBUT parameters were more effected inthe safety goggle group.
Conclusion: Both safety goggles and face shields have shown a significant decrease in values of tear film parameters. In comparison, safety goggles have a greater effect than face shields.
