This quasi-experimental study aims to compare the efficacy of three different modes of vision therapy—conventional in-office therapy, computer-based therapy, and mobile app-based therapy—in improving accommodative facility and reducing visual discomfort in adults diagnosed with accommodative inertia. A total of three groups will receive structured vision therapy over a 6-week period, with each group undergoing a different mode of delivery. The conventional group will receive therapist-guided, in-person therapy using standard clinical techniques. The computer-based group will perform vision exercises via desktop software at home, while the mobile app group will use a smartphone-based platform designed for accommodative training.

Primary outcomes will include changes in accommodative facility, while secondary outcomes will assess improvements in accommodative amplitude, visual symptoms, therapy adherence, and user satisfaction. The study will also analyze compliance rates and user feedback to understand the feasibility and acceptability of digital therapy solutions. The findings are expected to guide clinicians in selecting personalized, effective, and scalable vision therapy modalities—particularly for individuals with lifestyle constraints or limited access to in-office therapy. This research supports the broader integration of digital therapeutics and tele-optometry into routine eye care.
