Visual Field Test VS Diffyn

• Free and Accessible
  Visual Field Test is available online for free, making it accessible to anyone with a computer and internet connection without needing to visit an eye care professional for a preliminary screening.
• Convenient Home Testing
  Users can perform a basic visual field screening from the comfort of their home, which is especially useful for those who want a quick check between professional eye exams or have limited mobility.
• Easy to Use
  The web-based interface is straightforward and simple, requiring minimal technical knowledge to operate. Users can follow on-screen instructions to complete the test without specialized training.
• Quick Screening Tool
  The test can be completed relatively quickly, providing a fast preliminary indication of potential visual field defects that may warrant further professional evaluation.
• Awareness and Early Detection
  By offering an accessible screening tool, the platform helps raise awareness about visual field loss conditions like glaucoma and encourages users to seek professional care if abnormalities are detected.

Possible disadvantages

• Not a Medical Diagnostic Tool
  The test is not a substitute for a professional visual field test conducted with calibrated medical equipment such as a Humphrey or Goldmann perimeter. Results should not be used for clinical diagnosis or treatment decisions.
• Inconsistent Testing Conditions
  Unlike a controlled clinical environment, home testing variables such as screen brightness, monitor size, ambient lighting, and viewing distance can significantly affect accuracy and reliability of results.
• Limited Precision and Sensitivity
  The test lacks the precision and sensitivity of professional-grade perimetry equipment, meaning it may miss subtle visual field defects or produce false positives, giving users a misleading sense of security or unnecessary worry.
• Requires Self-Compliance
  The test relies on the user to properly fixate, cover one eye correctly, and respond honestly. Without a technician monitoring compliance, the results can be unreliable due to improper technique or accidental cheating.
• No Professional Interpretation
  Results are presented without the expert interpretation of an ophthalmologist or optometrist, which means users may misunderstand their results or fail to recognize the significance of detected abnormalities.

• Version Control
  Manage changes with visibility on all versions to enhance traceability for prompt for teams and professionals.
• Visualization
  Side-by-Side Viewer with diff highlighting on changes made and comparison of outputs across different LLM models.
• Advanced Analytics
  OpenAI powered assistant to provide analyisis on the test outputs and improvment. Gemini powered evaluation on cost efficiency, readability metrics
