The Impact of Soft Contact Lens Attributes on Symptoms Associated With Digital Eye Strain in Symptomatic Soft Contact Lens Wearers

Completed · Not applicable

Conditions studied: Asthenopia, Myopia

In brief

Despite its prevalence, the ocular causes of eye fatigue or unknown and may be related to the cornea/contact lens surface, the accommodative system, the convergence system, overall postural/muscle fatigue, or a combination of these or other causes. The current study aims to systematically investigate the incremental benefits in ameliorating eye fatigue.
