About

This Randomized Control Trials Study , conducted in Lahore, Pakistan, investigates the comparative efficacy of two approaches-plus lens addition of +0.75 diopters (D) and vision therapy using the HART chart-for managing accommodative infacility. Accommodative infacility, a condition characterized by the eye's reduced ability to adjust focus between distant and near objects, impacts both visual comfort and performance, particularly during prolonged near work.

Full description

The study sample comprises 38 participants, aged 15 to 35 years, divided into two groups: one group receiving plus lens addition of +0.75 D and the other undergoing structured vision therapy with the HART chart. Findings revealed that vision therapy was significantly more effective than plus lens addition, with results showing statistical significance at P < 0.05.
