Summary

With the widespread use of electronic display devices, the potential hazards of blue light have become an important public health issue. The primary assessment and main outcome indicators of this experiment are the evaluation of the protective effects of a new type of filtering glasses on visual fatigue in the human eye. Secondary outcome indicators include tear film break-up time, accommodative facility, and subjective visual fatigue scores. Other outcome measurement indicators include visual function indicators such as accommodation and convergence. Baseline values of the above indicators were measured separately, and then specific numerical values of different indicators were collected after working with VDT devices while wearing the new type of filtering glasses or regular framed glasses. These values were statistically compared and analyzed with the baseline values. The study aims to assess the impact of the new type of filtering glasses on relieving visual fatigue and improving visual function.
