Medical & Legal Disclaimer
Please read these important disclaimers before using RGBlind's color vision testing and simulation tools. Understanding these limitations is crucial for safe and appropriate use.
Medical Disclaimer
Not a Medical Device
RGBlind is not a medical device and has not been evaluated or approved by any medical regulatory authority. Our color vision tests and simulations are educational tools designed to raise awareness about color accessibility, not to diagnose medical conditions.
Limitations of Online Testing
Online color vision tests have significant limitations that can affect accuracy:
- Monitor color calibration and display settings
- Ambient lighting conditions
- Screen brightness and contrast settings
- Device-specific color reproduction
- Browser and operating system variations
- User fatigue and attention levels
Professional Testing Required
For accurate diagnosis of color vision deficiency or any eye condition, you must consult a qualified eye care professional such as:
- Ophthalmologists (medical doctors specializing in eye care)
- Optometrists (eye care professionals)
- Certified vision specialists
- Pediatric eye specialists (for children)
Children's Testing: Color vision testing in children requires specialized professional evaluation. Online tests should never be used to make educational or medical decisions about a child's vision.
Technical Limitations
Simulation Accuracy
While RGBlind uses scientifically-based algorithms for color vision simulation, the accuracy depends on multiple factors:
- Individual variations in color vision deficiency
- Severity levels of color vision conditions
- Display technology and calibration
- Environmental viewing conditions
Ishihara Test Limitations
Our Ishihara-style tests are simplified versions for educational purposes and should not be compared to standardized medical Ishihara plates used by professionals.
Device Compatibility
Results may vary significantly between different devices, browsers, and operating systems. Mobile devices may have particular limitations in color accuracy.
