Vision Test Guidelines
A clear, step-by-step guide to completing your vision assessment accurately and safely.
About the Assessment
This digital vision screening uses your device camera to estimate visual acuity in a structured, child-friendly format. It is designed to support ongoing monitoring and therapy — not to replace a clinical eye examination.
Before You Begin
- Use a well-lit room with even lighting — avoid glare on the screen or strong backlighting.
- Position your face clearly in view of the front camera.
- Hold the device at arm's length, approximately 30–40 cm (12–16 inches) from your eyes.
- Keep the device steady throughout the test.
- Remove glasses if the assessment is intended to measure natural vision, unless your clinician advises otherwise.
How the Test Works
1. Calibration
The application verifies distance and lighting using the camera. On-screen prompts will guide you if any adjustment is needed.
2. Practice Round
A short practice sequence helps you understand how to respond before the scored assessment begins.
3. Visual Acuity Test
Symbols (such as E or C optotypes) are displayed at varying sizes. Indicate the direction of the opening or select the matching symbol. Difficulty adapts based on your responses. Eye-specific presentation is handled automatically — manual eye covering is not required.
4. Eye Tracking
The front camera monitors gaze position to support measurement consistency and reliability scoring.
5. Results
Upon completion, you will receive:
- Visual acuity estimates for each eye
- Measurement reliability indicators
- Environmental quality notes (lighting and contrast)
- Date and time of the session
After the Test
- Results are saved automatically to your profile.
- A structured report is available in your Dashboard and Reports section.
- Repeat the assessment periodically to track progress over time.
Important Information
- This tool provides vision screening support only and does not constitute a medical diagnosis.
- Consult a qualified eye care professional for abnormal results or clinical concerns.
- Children should be supervised during testing to ensure accurate responses.
