PeekVision.io's Accessible Vision Test provides a simplified large-letter vision screening with spoken instructions, optional voice responses, large controls, and no time limit.
It is intended to make preliminary visual-acuity screening easier for people who have difficulty reading the smaller starting letters used by a standard vision test.

The screening begins with very large black letters on a white background.
PeekVision can read the test instructions aloud to help users follow the eye-covering and viewing-distance steps.
Users may choose to speak the five letters shown on the screen instead of relying only on mouse or touch controls.
Manual “I Can Read” and “I Can't Read” buttons remain available if voice recognition is unavailable or not preferred.
Users can take the time they need to view and respond to each line.
Large-Letter Vision Levels
The Accessible Vision Test begins with larger visual-acuity screening levels and progresses toward smaller letters.
The current screening range includes:
- 20/400
- 20/320
- 20/250
- 20/200
- 20/160
- 20/125
- 20/100
- 20/80
- 20/63
- 20/50
How the Accessible Vision Test Works
- Calibrate your screen first. PeekVision will calculate a viewing distance that allows the large-letter test to fit your display.
- Use your usual distance glasses or contacts if appropriate.
- Begin with the right eye while covering the left eye.
- Read five letters from left to right.
- Respond by voice or use the large on-screen buttons.
- Repeat the test for the left eye.
- Finish with both eyes open.
- Review the screening report.
How Voice Assistance Works
If voice assistance is enabled, PeekVision reads only the instructions aloud. It does not read the test letters because doing so would reveal the answer.
When microphone access is allowed, the user may speak the five letters shown on the screen. Speech-recognition accuracy can vary based on pronunciation, browser support, microphone quality, background noise, and operating-system behavior.
Manual response buttons remain available as an alternative.
Who May Find This Test Helpful?
The Accessible Vision Test may be easier to use for people who:
- Have difficulty seeing smaller starting letters
- Prefer large, high-contrast controls
- Benefit from spoken step-by-step instructions
- Prefer speaking responses rather than using a mouse or touchscreen
- Need more time to respond
Is This a Low-Vision Diagnosis?
No. The Accessible Vision Test is a preliminary browser-based screening. It does not diagnose low vision, legal blindness, retinal disease, glaucoma, cataracts, refractive error, or any other eye condition.
Screening Limitations
Results can be influenced by:
- Physical screen size
- Display scaling and browser zoom
- Viewing distance
- Lighting
- Screen brightness
- Eye covering technique
- Speech-recognition errors
- User responses
When Should You Seek Professional Eye Care?
Consider a comprehensive eye examination if your results remain reduced, one eye performs significantly differently from the other, or you have difficulty seeing in everyday life.
Sudden loss of vision, severe eye pain, new flashes or floaters, or eye injury should be evaluated promptly by an eye-care professional.
