The Effect of Using Blue Light Filter Feature on Smartphones with Asthenopia Occurrence

Abstract

Background: Smartphone users can be found in almost every class society in Indonesia. Excessive use of smartphones and the blue light emitted by smartphones play an important role in causing asthenopia symptoms. Smartphone development companies have developed a blue light filter feature, which is expected to reduce the incidence of Asthenopia symptoms.Objective: To evaluate the Asthenopia questionnaire's comparison results before and after smartphone use with various levels of opacity in the blue light filter.Methods: This study used a quasi-experimental pre-posttest study. The research subjects were students of the Faculty of Medicine, Diponegoro University (n = 30), selected by purposive sampling. In this study, research subjects saw an hour-long smartphone with a predetermined opacity level for the blue light filter, with the same room lighting. Before and after the treatment, the subjects were asked to fill out the Asthenopia questionnaire. Data were analyzed using the Wilcoxon test, Mann Whitney U test, and Kruskal Wallis test.Results: The results of the Asthenopia questionnaire before and after using a smartphone with a blue light filter opacity level of 0% and 100% showed a significant difference in results (p <0.05), and there was no significant difference for the pre-posttest using a smartphone with a blue light filter with 50% opacity level. The comparison results of the Asthenopia questionnaire between smartphone use with the opacity level of the blue light filter 0% and 50% only showed a significant difference in sore/aching eye symptoms. The comparison results of the Asthenopia questionnaire between smartphone use with the opacity level of the blue light filter 50% and 100% only showed a significant difference in sleepy eye symptoms. The comparison results of the Asthenopia questionnaire between smartphone use with the opacity level of the blue light filter 0%, 50%, and 100%, did not show a significant difference.Conclusion: There were no significant differences between the Asthenopia questionnaire results with 0%, 50%, and 100% opacity blue light filters after one hour of smartphone use.

Pengaruh Filter Blue Light terhadap Durasi Penggunaan Handphone saat Kuliah Online pada Mahasiswa di Era Pandemi Covid-19

“…Hal ini diperkuat oleh studi yang dilakukan oleh Palavets dan Rosenfield yang menunjukkan bahwa penggunaan filter yang mampu mengurangi pancaran cahaya biru dari tablet hingga 99% dinyatakan tidak efektif dalam mengurangi gejala CVS dibanding kelompok kontrol. American Academy of Opthalmology juga menyatakan bahwa penggunaan lensa penghalang cahaya biru tidak direkomendasikan karena dinyatakan tidak adanya perbaikan gejala dari CVS [25,26,27].…”

Analisis Reduksi Spektrum Sinar Biru Berbasis Papercraft Spectrometer pada Layar Ponsel Pintar Berjenis LED

“…Durasi penggunaan yang cenderung lama akan memberikan efek pada tubuh (Wiryawan, Kesoema, & Prihatningtias, 2021). Selain berdampak pada nyeri leher dan bahu, penggunaan ponsel pintar secara intensif juga akan menimbulkan gejala gangguan penglihatan.…”

“…Teknologi jenis ini memiliki keunggulan dalam hal variasi warna, kontras, resolusi dan kemampuan untuk menghasilkan layar yang lebih tipis (Heo et al, 2016). Walaupun terlihat berwarna putih, namun cahaya yang dipancarkan dari layar ponsel pintar memiliki panjang gelombang 400 nm sampai dengan 490 nm, yang tergolong dalam kategori sinar biru (Wiryawan et al, 2021).…”

“…Demi keselamatan, berbagai metode digunakan untuk mengurangi paparan radiasi sinar biru. Penelitian tentang penggunaan fitur filter sinar biru bawaan ponsel atau aplikasi pihak ketiga terhadap kesehatan telah dilakukan (Calvosanz & Tapia-ayuga, 2020;Heo et al, 2016;Mitropoulos, Tsiantos, Americanos, Sianoudis, & Skouroliakou, 2020;Wiryawan et al, 2021). Dua saran umum yang dapat dilakukan untuk mengurangi paparan radiasi sinar biru yaitu pengurangan cahaya tingkat tinggi yang tidak perlu di malam hari dan redaman komponen panjang gelombang pendek dari spektrum (Mitropoulos et al, 2020).…”
