Educational Calculators

Vision Symptom Explorer

Educational pathways for common vision symptom patterns — not a diagnostic algorithm or triage bot.

Overview

People search symptom questions because vision changes are stressful. This explorer asks structured educational questions — one eye or both, sudden or gradual, pain, flashes, floaters — and returns learning pathways with proportionate care guidance.

It is not a diagnostic algorithm, not emergency dispatch, and not personalized medical advice.

How to use this tool

Follow these educational steps:

  1. Select the features that best match your situation without over-selecting every box.
  2. Read the pathway summary and linked symptom articles.
  3. Pay special attention to urgent-feature warnings when present.
  4. When in doubt about severity, contact a clinician or emergency services rather than re-running the tool.

What results can mean

Pathways highlight common educational associations (for example, gradual blur with refractive error vs sudden curtain-like loss with urgent retinal concerns). Associations are not probabilities for you personally.

What results do not mean

Does not diagnose retinal detachment, stroke, migraine, or infection.

Does not tell you to ignore severe symptoms if a pathway sounds reassuring — urgent features always override.

Limitations

Important limitations:

  • Checkbox tools miss nuance and rare diseases.
  • Self-report timing can be inaccurate when stress is high.

When to see an eye-care professional

Use linked articles to prepare questions for clinicians. Seek in-person care for persistent or worrying symptoms.
