AI Vision Screening Pilot — RMG Factory, Dhaka EPZ

847 sewing operators screened using AI computer vision diagnostics. 61.3% found to have uncorrected refractive errors above clinical threshold.

Location: BGMEA-affiliated export garment factory, Dhaka EPZ
Date: Q1–Q2 2026
Study subjects: 847 sewing operators
Technology: Nevronus Systems AI computer vision diagnostic pipeline
Cost: BDT 1,100 per worker (screening + eyewear). Employer payback period: 4.8 months.

Methodology: Stratified random sampling; double-blind QC measurement; pre/post design with matched control group.

  • Uncorrected refractive errors above clinical threshold: 61.3%
  • Production rate increase post-correction (8-week cohort, n=312): +8.2% units/hr
  • QC error-rejection rate reduction vs. control group: −14.6%
  • Worker fatigue score — baseline: 6.8 / 10 → post-correction: 4.1 / 10

Date: Q4 2025–Q1 2026
Study subjects: 7,740 teachers
Technology: Nevronus Systems Smart Digital Attendance Platform
Cost: BDT 48,000 per school (hardware + installation)

Methodology: Pre-post comparative design; matched control schools in adjacent upazilas.

  • Headmaster daily admin time: 47 min/day → 11 min/day (76.6% reduction)
  • Data transmission lag: 3–5 days → <4 hours
  • Teachers flagged for HR review: 2.3%
