asthenopia
Pronunciation: as-then-OH-pee-ah
Eye strain or visual fatigue characterized by discomfort, aching, or tiredness of the eyes, often associated with prolonged visual tasks.
Full Definition
Asthenopia, commonly referred to as eye strain, encompasses a group of symptoms including ocular discomfort, aching, burning, tearing, and visual fatigue that typically occur during or after prolonged visual work. These symptoms can result from accommodative dysfunction, binocular vision disorders, uncorrected refractive errors, or dry eye syndrome. In the modern era, digital asthenopia (computer vision syndrome) has become increasingly common due to prolonged screen use. The condition is often multifactorial and requires comprehensive evaluation of refractive status, binocular function, and ocular surface health.
Usage
Usage note: Preferred clinical term for 'eye strain'; consider multiple potential etiologies when evaluating.
