Abstract: Visual impairments, such as refractive errors, can reduce quality of life. The increasing use of gadgets, especially among students, is often linked to visual disturbances due to blue light exposure. This study aimed to analyze the relationship between blue light exposure from gadgets and visual acuity among class of 2021 medical students at Universitas Sam Ratulangi. This was an observational and analytical study with a cross-sectional design. Data were collected using questionnaires and Snellen chart, and were analyzed with the Fisher’s Exact Test at a 0.05 significance level. The results showed that the majority of respondents (98%) had high durations of blue light exposure. Normal visual acuity in the right eye was found in 46% of respondents, while normal visual acuity in the left eye was observed in 48%. The Fisher’s exact test showed a p-value of 1.000 for the relationships between blue light exposure duration and visual acuity in the right and left eyes, indicating no significant relationship. In conclusion, there are no significant relationships between the duration of blue light exposure from gadget and visual acuity of right and left eyes. Further research is needed to explore other influencing factors.

Abstrak: Gangguan penglihatan, seperti kelainan refraksi, dapat menurunkan kualitas hidup. Penggunaan gadget yang semakin meningkat, khususnya di kalangan mahasiswa, sering dikaitkan dengan risiko gangguan penglihatan akibat paparan sinar biru. Penelitian ini bertujuan untuk menganalisis hubungan antara paparan sinar biru dari gadget dengan ketajaman penglihatan pada mahasiswa Fakultas Kedokteran Universitas Sam Ratulangi angkatan 2021. Penelitian ini menggunakan desain observasional analitik dengan desain potong lintang. Data dikumpulkan melalui kuesioner dan Snellen chart, kemudian dianalisis menggunakan uji Fisher’s exact test dengan nilai signifikansi 0,05. Hasil penelitian mendapatkan mayoritas responden (98%) memiliki durasi paparan sinar biru yang tinggi. Ketajaman penglihatan mata kanan normal ditemukan pada 46% responden, sementara ketajaman penglihatan mata kiri normal ditemukan pada 48% responden. Uji Fisher's exact test menunjukkan nilai p=1,000, baik untuk hubungan durasi paparan sinar biru dengan ketajaman penglihatan mata kanan maupun mata kiri, sehingga tidak ditemukan hubungan bermakna. Simpulan penelitian ini ialah tidak terdapat hubungan bermakna antara durasi paparan sinar biru dari gadget dengan ketajaman penglihatan mata kanan dan kiri. Studi lebih lanjut diperlukan untuk mempertimbangkan faktor-faktor lain.
