Abstract

LED-producing gadgets are prevalent nowadays and can be found in almost all devices that an individual use. LEDs (Light-Emitting Diodes) are used to illuminate different things, but these also emit blue light, which is harmful in prolonged use. Experiments conducted show that blue light can cause photoreceptor damage and affect the body's circadian rhythm. The corneain the human eye can accommodate light waves below 300 nm on average, with blue light ranging in 380-400 nm (Lievens, 2019). This study aims to find the characterized effects of blue light exposure on the eyesight of the DLSMHSISenior High students as they are exposed to different gadgets during synchronousclasses and in the COVID-19 Pandemic. A quantitative descriptive research designis utilized in this study to describe the phenomena that the students are currently facing. Data were analyzed using Student’s T-Test, Variance, and Standard Deviation. In this study, most students are exposed to more than 4 hours in synchronous classes, and a majority of the subjects felt the symptoms 2-3 times a week. The computed t-score of the respondents is 2.785, which means that the null hypothesis is rejected, and there is a significant effect on the eyesight of the subjects. Since there is a significant effect, it means that the eyesight of the students worsened during the tenure of the Pandemic and in synchronous classes, and the clarity of vision of the students is affected by the symptoms aforementioned in the study.
