Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To evaluate the effect of selected optical filters on overall visual performance in low vision patients by assessing changes in visual function (distance and near visual acuity, contrast sensitivity), visual fatigue (Visual Fatigue Scale), and quality of vision (QoV questionnaire) from baseline (without filter) to immediate post-filter assessment.Timepoint: Baseline (without filter) and Immediate post-intervention (with filter) | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Patient Adaptation and Satisfaction 2. Awareness, perception, and utilization of optical filters among low vision practitioners 3.Development of clinical guideline/module for filter prescriptionTimepoint: 1. 4 weeks post filter adoption (only for participants who purchase filter) 2.Single time point 3. After completion of Delphi rounds | — |
