Contrast Sensitivity and Asthenopia Analysis in Workers

Abstract

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.
