Visual Acuity
Adaptive letter-identification tests that find the smallest optotype a person can resolve, across both static and dynamic presentations.
Method: Snellen / LogMAR, 14 levels from 20/200 to 20/10, ETDRS-validated Sloan letters.
Vision & cognitive assessment platform
A window into brain health, through the eyes and hands.
VizScore is a clinically grounded assessment suite for sports teams, vision clinics, concussion programs, and research institutions — standardized tests that quantify visual, cognitive, and motor performance.
Built on the clinical standards practitioners already use
- Snellen / LogMAR
- Pelli-Robson
- Pylyshyn MOT
- Reitan TMT
- Bassin Timing
- ETDRS
- VOMS
What VizScore measures
Assessments across every performance domain
Each domain pairs a modern mobile experience with decades of peer-reviewed methodology — so you can trust the number you see on the screen.
Contrast Sensitivity
Identifies the lowest contrast at which a person can still read letters — the functional vision measure that acuity alone misses.
Method: Pelli-Robson triplets, 0.15 log-CS steps, 16 contrast levels.
Reaction Time
Visual-motor reaction task capturing both speed and consistency — a staple metric for concussion baselines, ADHD evaluation, and sports performance.
Method: Age-stratified percentiles, coefficient-of-variation consistency scoring.
Tracking
Sustained smooth-pursuit and eye-hand coordination tasks — measuring target following and visuomotor adaptation under sustained demand.
Method: VOMS smooth-pursuit paradigm; Kim et al. visuomotor adaptation.
Working Memory
Multiple object tracking measures how many moving targets you can hold in mind at once — a foundational visual-cognitive capacity.
Method: Pylyshyn & Storm (1988) MOT paradigm.
Peripheral Vision
A dual-task paradigm: hold central fixation while detecting and identifying peripheral color stimuli at 85–95% eccentricity.
Method: UFOV-style dual-task detection; per-side asymmetry scoring.
Motor Precision
Coincidence-anticipation timing — tap exactly as the indicator reaches the target zone. Sensitive to motor timing deficits seen in TBI and Parkinson's.
Method: Bassin Anticipation Timer; absolute, constant, and variable error scoring.
Executive Function
Connect circles in sequence — Part A (numbers) for processing speed, Part B (alternating numbers and letters) for cognitive flexibility.
Method: Reitan TMT with Tombaugh (2004) age- and education-adjusted norms.
For Organizations
Built for the way teams actually test
VizScore is purpose-built for organizations administering assessments at scale — on a sideline, in a clinic, or across a multi-site study.
Offline field testing
Run a full battery on 30+ athletes at a stadium or training facility with zero connectivity. Results sync automatically when you're back online.
Standardized test batteries
Assemble custom sequences — pre-season screening, return-to-play, longitudinal monitoring — and push them to every device in your organization.
Participants & groups
Import rosters via CSV, tag participants by team or position, track external IDs (jersey numbers, medical records), and review every session per participant.
Role-based access
Owner, admin, staff, and participant roles with granular visibility controls. Configure who sees which results across your org and which data stays local.
Rich data export
CSV for your spreadsheet, JSON for your pipeline. Every tap is timestamped with device metadata for reproducibility and audit-ready analytics.
Adaptive training programs
Six trainable skills with staircase algorithms that find each individual's threshold and push it forward. Measure the gain, not just the baseline.
The science
The instruments practitioners already trust — redesigned for the field
Every VizScore assessment implements a peer-reviewed paradigm with documented normative data. The references below are the same ones cited in ophthalmology and neuropsychology training.
Visual acuity
14-level LogMAR progression using the ETDRS-validated Sloan letter set — the industry standard for measuring the smallest optotype a person can resolve.
Contrast sensitivity
Pelli-Robson triplet methodology in 0.15 log-CS steps. Detects functional vision loss that standard acuity testing can miss — critical for driving, aging, and disease monitoring.
Multiple Object Tracking
The canonical MOT paradigm measures working-memory capacity for moving targets — a visual-cognitive benchmark with documented sensitivity to concussion and ADHD.
Trail Making Test
Part A for processing speed and Part B for cognitive flexibility, scored against Tombaugh's age- and education-stratified norms (n=911). Among the most widely used neuropsych tests in the world.
Coincidence-anticipation timing
Bassin Anticipation Timer methodology capturing absolute, constant, and variable error — the gold standard for motor timing research in TBI and Parkinson's.
Smooth-pursuit tracking
Derived from the Vestibular/Ocular-Motor Screening protocol — a validated concussion-screening framework for pursuit-gain measurement.
Visuomotor adaptation
Sight of Hand layers a proprioceptive offset onto target tracking — a sensitive marker of motor variability that standard tracking tasks don't capture.
Peripheral color detection
Dual-task paradigm enforcing central fixation while detecting eccentric color stimuli — assesses the peripheral awareness that predicts driving and fall-risk outcomes.
VizScore is a digital adaptation of these clinical instruments, built for screening, performance monitoring, and research. It is not a diagnostic device and is not a substitute for evaluation by a licensed clinician.
Who uses VizScore
