About
Canthal Tilt Test is a free visual tool designed to estimate canthal tilt, eye shape, and eye color from a single portrait photo.
Why this tool exists
People often want a faster way to check eye-area traits for styling and self-comparison without manual measurements. This tool gives a structured, repeatable estimate in seconds.
How the analysis works (high level)
The model analyzes visible eye-region cues such as inner and outer eye-corner position, lid contour, and iris appearance. It returns:
- Estimated canthal tilt category and angle
- Estimated primary eye-shape category
- Estimated dominant eye color with confidence context
Accuracy and limitations
This is an appearance-based estimate, not a medical or biometric instrument. Results can shift based on lighting, head tilt, makeup, reflections, and photo quality.
- Not intended for medical diagnosis or treatment
- Best used for directional interpretation and comparison
- Use consistent photo setup when tracking changes over time
Privacy
Privacy matters. Upload only images you are comfortable processing through an AI service, and review the Privacy Policy for data-handling details.
Who should use this tool
- People who want a quick canthal tilt estimate from a portrait
- Users comparing eye-shape scans across similar photos
- Anyone seeking non-medical visual analysis for styling context
Who should not rely on this tool
- Anyone needing clinical or diagnostic assessment
- Anyone requiring high-precision biometric measurements
