Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Quantification of the "frame-face mismatch" by comparing 7 key facial anthropometric parameters (measured using the Fairbanks Facial Gauge) with current spectacle frame dimensions (measured using the ABDO Frame Rule).Timepoint: As this is a cross-sectional observational study, participants are evaluated only once during a single 20-30 minute visit, with no follow-up period required. Therefore, the time points for both the primary and secondary outcomes have been updated to Day 1 to accurately reflect this single-assessment design. | — |
Secondary
| Measure | Time frame |
|---|---|
| Immediate improvement in visual comfort and frame stability following on-the-spot minor frame adjustments (rectification).Timepoint: Immediately following the primary assessment and rectification (Day 1). | — |
