OculusAI • Optometric Examination
Digital Visual Acuity Screener
Standardized Tumbling E directional resolution testing based on ISO 8596 angular resolution.
Distance: 1.0 meter (approx. arm's length)
Test Instructions
The Tumbling E optotype will be presented on screen in one of four directions (Up, Right, Down, Left). As you progress, the optotype progressively decreases in physical angular size.
Calibration & Protocol
- Position yourself approximately 1 meter (arm's length + 30cm) from your screen.
- Cover one eye for monocular testing, or keep both eyes open for binocular screening.
- Ensure corrective lenses (glasses/contacts) are worn if usually required for screen distance.
- Use keyboard arrow keys or on-screen directional controls.
