PENGARUH ANTARA PAPARAN CAHAYA BIRU LAYAR KOMPUTER DENGAN COMPUTER VISION SYNDROME (CVS) PADA MAHASISWA FK UMM

Background : The intensive use of digital devices in academic activities increases
exposure to blue light, which potentially contributes to the development of Computer
Vision Syndrome (CVS). CVS has become a common complaint among students,
especially those who spend extended periods in front of computer screens.
Method : This study aimed to investigate the effect of blue light exposure from
computer screens on the incidence of CVS among medical students at the Faculty of
Medicine, University of Muhammadiyah Malang. An observational analytic approach
with a cross-sectional design was employed. A total of 125 students were selected using
purposive sampling. Data were collected using a modified version of the CVSS17
questionnaire.
Results : The majority of respondents (82.4%) experienced mild to moderate levels of
CVS. A significant association was found between the use of eyeglasses, lens types,
and blue light screen protectors with the severity of CVS (p < 0.05). Students who used
protective measures, such as blue-ray lenses and screen filters, reported milder CVS
symptoms.
Conclusion : Blue light exposure is associated with the incidence of CVS. The use of
protective measures, such as specialized lenses and screen protectors, has been proven
to reduce the severity of CVS symptoms. Educational efforts on prevention and
management of blue light exposure are strongly recommended to reduce CVS risk
among students.
