In the digital age, complaints of eyestrain, or asthenopia, have become increasingly common. This condition is often associated with prolonged near-work activities, such as extended use of computers or digital devices, with reported prevalence rates ranging from 40% to 90%. Eye fatigue is influenced by a decline in the eye’s accommodative capacity. Optimal visual function and acuity contribute to reducing visual discomfort by enhancing contrast sensitivity – the ability to clearly and precisely discern the boundaries of microscopic or fine-detail objects.
Materials and Methods
The study design was observational analytics and a cross-sectional approach. The number of patients was 94 people aged 18-60 years, without having anatomical abnormalities of the eye in the form of corneal opacities, cataracts, turbidity of refractive media, and retinal abnormalities. Research instruments in the form of asthenopia questionnaires and Pelli Robson charts were used to examine eye contrast sensitivity. Results 84% of respondents in this study were aged > 25 years, 72.4% had worked for > 2 years, and 34% did close viewing activities for 2-5 hours/day. The incidence of asthenopia was 76.6%, and 96.8% had normal eye contrast sensitivity ability. Analysis using the chi-square test showed no significant relationship (p = 1,000) between contrast sensitivity and asthenopia.
Conclusion
There was no significant relationship between contrast sensitivity and asthenopia.
