Visual Field Test - Detect Blind Spots Online

What

Visual Field Test is a browser-based tool for at-home peripheral vision screening and longitudinal monitoring. It lets people test the left eye, right eye, or both eyes together, then review saved results over time with AI-assisted analysis intended to highlight patterns and possible changes.

The product appears positioned as an educational screening and self-monitoring aid for individuals concerned about glaucoma or other vision-related changes, rather than as a clinical diagnostic system. Its workflow is straightforward: cover one eye, keep focus on a central fixation point, and respond when light flashes appear in different parts of the screen.

Features

• Simple and Advanced test modes — Simple mode offers a quick check without calibration, while Advanced mode uses screen calibration and threshold testing to estimate sensitivity at each point.
• Left eye, right eye, and full-field testing — Users can assess each eye individually or test both eyes together for a broader functional view similar to driving-style assessments.
• AI-assisted result analysis — Test outputs are analyzed to identify patterns and flag potential areas of concern, helping users interpret peripheral vision changes.
• History and trend tracking — Saved results can be compared side by side to monitor visual field changes over time and support conversations with an eye care professional.
• Reliability and retest logic — The tool checks reliability through false-click monitoring and rechecks missed points to improve screening consistency.
• Multilingual access — The interface, instructions, and AI analysis are available in 30 languages, which supports broader accessibility for global users.

Helpful Tips

• Treat this kind of tool as a screening and monitoring aid, not a replacement for professional eye exams; the page explicitly says it is educational use only and not a medical device.
• For repeat testing, keep conditions consistent — same screen, viewing distance, lighting, and test mode — so trend comparisons are more meaningful.
• If detailed monitoring matters, use the Advanced mode when possible, since the page indicates it measures sensitivity point by point after calibration.
• Encourage users to share longitudinal results with an eye care professional, because trend data is often more useful than a single at-home test.
• Be cautious about over-interpreting alerts or changes; the page suggests the tool can help detect patterns associated with eye or neurological concerns, but it does not claim to diagnose them.
