Nowadays, watching television has become an integral part of children's daily activities. Albeit, TV can have a negative impact on their eyes due to the produced blue light. In the spectrum of light, this blue light is acceptable to the eye but it can cause eye damages by the free radicals produced. The risk of the damage depends on the light length and the exposure intensity. This study aimed to determine whether there is a correlation between the distance of watching TV and the duration of exposure to the blue light from TV with the refraction by measuring visual acuity. This was a cross-sectional study. The population was students of grade 1 to grade 5 of the GMIM 20 elementary school, Manado. Samples were 30 students who underwent visual acuity measurement. The results showed a P-value > 0.05 by using a linear regression. The correlation of the distance of watching TV and the duration of exposure to the blue light with the visual acuity of the right eyes showed a P-value of 0.184 and of the left eyes a P-value of 0.967. Conclusion: Among the GMIM 20 elementary school students in Manado there was no correlation between the distance of watching TV and the duration of exposure to the blue light of the television with eye refraction. Keywords: television, blue light, exposure.     Abstrak: Dewasa ini, televisi telah merupakan alat informasi dan hiburan yang terintegrasi dalam aktivitas keseharian anak-anak. Televisi bisa berdampak buruk bagi kesehatan mata akibat sinar biru yang dihasilkan. Sinar biru terdapat pada spektrum yang masih dapat diterima oleh mata, namun dapat menyebabkan kerusakan mata akibat oleh radikal bebas yang dihasilkannya. Risiko kerusakan mata tergantung pada panjang cahaya dan intensitas paparan. Penelitian ini bertujuan untuk mengetahui hubungan antara jarak dan lama paparan sinar biru pesawat televisi terhadap fungsi refraksi dengan melakukan pengukuran tajam penglihatan. Penelitian ini menggunakan cross-sectional design, dan mengikutsertakan siswa kelas 1 sampai kelas 5 SD GMIM 20 Manado sebagai populasi. Pada sampel sebanyak 30 siswa dilakukan pengukuran tajam penglihatan. Hasil penelitian dengan regresi linier memperlihatkan nilai P > 0,05. Korelasi jarak dan lama paparan sinar biru televisi terhadap tajam penglihatan mata kanan memperlihatkan nilai P = 0,184, dan terhadap tajam penglihatan mata kiri P = 0,967. Simpulan: Tidak terdapat hubungan antara jarak dan lama paparan sinar biru pesawat televisi terhadap fungsi refraksi siswa di SD GMIM 20 Manado. Kata kunci: televisi, sinar biru, paparan.
