Training & Certification
Standardized Training Supports Reliable Visual Assessment
Reliable visual assessment depends on standardized procedures, consistent examiner techniques, and controlled testing environments.
Precision Vision training and certification programs are designed to help support:
- Standardized testing methodologies
- Reduced examiner variability
- Consistent patient assessment
- Reliable visual function measurement
- Reproducible testing outcomes
- Protocol-aligned procedures
PRODUCT CATEGORIES
Vision testing instruments engineered for measurement integrity.
Six instrument families covering visual acuity, contrast sensitivity, color vision, low vision, reading speed, and pediatric testing. Every product validated and peer-reviewed.
Visual Acuity Charts
ETDRS Revised 2000, Sloan Letters, HOTV, Lea Symbols, and pediatric optotypes. The standard for retinal trials, ophthalmology research, and clinical practice for over 50 years.

Reducing Variability Through Standardized Procedures
Variability can impact visual assessment outcomes across clinical and research environments.
Precision Vision training programs are designed to help minimize variability associated with:
- Inconsistent testing techniques
- Non-standardized patient coaching
- Environmental testing differences
- Site-to-site procedural variation
- Equipment inconsistencies
- Protocol interpretation differences
Our standardized methodologies help support greater consistency and reproducibility across visual assessment environments.
Training & Certification
Site Certification & Examiner Training
Precision Vision supports standardized examiner training and site certification programs designed to align testing procedures across clinical, educational, and research environments.
Our certification programs help support:
- Standardized ETDRS methodologies
- Consistent visual acuity assessment
- Functional vision testing alignment
- Contrast sensitivity testing procedures
- Pediatric vision assessment consistency
- Protocol-compliant testing environments
These programs are designed to support reliable visual function assessment across examiners, sites, and patient populations.

Bestsellers across clinical practice and clinical research. Every product manufactured in Woodstock, Illinois under ISO 13485:2016 quality management.
Our Vision
Protocol-Aligned Vision Testing Methodologies
Precision Vision training programs are designed to align visual assessment methodologies with standardized testing procedures and endpoint requirements.
Our training supports:
- Best corrected visual acuity (BCVA) assessment
- Contrast sensitivity testing
- Functional vision evaluation
- Reading acuity assessment
- Low vision testing
- Pediatric visual assessment
Standardized methodologies help support reliable and reproducible visual assessment across testing environments.
Gold Standard
Most measurement variance in clinical trials traces to investigator drift. Standardized training plus annual recertification plus remote QA monitoring is the difference between a clean endpoint dataset and an FDA query. We've built our certification programs around the realities of multi-site execution — not theory. Trainers are PV's in-house experts plus contracted clinical educators with site-investigator backgrounds.
Support
Global Deployment & Ongoing Support
Precision Vision supports practices, institutions, and research environments through ongoing training support and standardized implementation methodologies.
Our support services help organizations maintain:
- Consistent testing procedures
- Standardized examiner performance
- Reliable testing environments
- Ongoing quality alignment
- Visual assessment consistency
Our solutions are utilized globally across ophthalmology, optometry, low vision, education, and research environments.
189 investigators, 47 sites, 16 weeks to full certification.
A Phase III geographic atrophy program required ETDRS-certified investigators across 47 sites in 14 countries. PV delivered initial certification, scheduled annual recerts, and ran remote QA monitoring through database lock — catching three drift events before any reached the endpoint dataset.
"The remote QA monitoring caught two protocol-deviation patterns we wouldn't have caught for months. Both flagged investigators were retrained within a week."

Lane Certification & Standardization
Lane Certification & Standardization
What is lane certification?
Lane certification helps ensure visual assessment environments meet standardized requirements for lighting, testing distance, chart positioning, and patient setup.
Why is lane standardization important?
Standardized testing environments help improve consistency and reduce variability across patient assessments.
What factors can impact testing variability?
Variability may result from:
Environmental lighting differences
Inconsistent chart positioning
Examiner variability
Non-standardized procedures
Testing distance inconsistencies
Patient coaching differences
Does Precision Vision provide examiner certification?
Yes. Precision Vision supports examiner training and certification programs designed to improve consistency and reproducibility in visual assessment.
