  <h1>Scotoma Mapping Tool</h1>

  <p>
    This experimental tool helps you map visual blind spots using dynamic noise.
  </p>

  <h3>Instructions</h3>
  <ul>
    <li>Use one eye at a time (cover the other)</li>
    <li>Keep your gaze fixed on the center cross</li>
    <li>Click where you perceive distortions, missing or unstable areas</li>
    <li>Maintain a consistent viewing distance</li>
  </ul>

  <h3>What you may notice</h3>
  <ul>
    <li><b>Central blind spot</b>: missing or altered area near fixation</li>
    <li><b>Distortions</b>: noise appears warped or unstable</li>
    <li><b>Faded zones</b>: reduced contrast, blurry gray spots or a flickering sensation. You may see some sparkling stars</li>
  </ul>

  <!-- OPTIONAL SETTINGS -->

        <option value="right">Right eye</option>
      </select>
    </label>

<!-- INFO POST TEST -->
<div id="info" style="display:none;">
  <p>
    You can export your results and repeat the test over time to track changes.
  </p>

  <p>
    For consistency, use the same screen, distance, and test conditions.
  </p>

  <p>
    You may share the exported file with your eye specialist if needed.
