Disclaimer

• Educational purpose: Screening tools on BlindnessTest.com are intended for education, awareness, and general interest. Results may help you notice possible color vision differences and decide whether to follow up with a professional.

• Not a clinical diagnosis: The assessment does not diagnose any medical condition and does not replace evaluation by a licensed optometrist, ophthalmologist, or other qualified eye care professional.

• Not for occupational clearance: Do not use online results for employment decisions, licensing, certification, aviation, maritime, railway, or other regulated occupational clearance unless your employer, examiner, or regulator explicitly accepts self-administered online screening. Supervised testing with approved equipment is often required.

• Not for emergencies: If you have sudden vision changes, eye pain, or other urgent symptoms, contact a doctor or emergency services. This site is not an emergency service.

Color vision is complex. Any brief online screening simplifies that complexity. Do not treat session results as a complete or permanent medical record.

Clinical color vision exams use controlled lighting, calibrated equipment, standardized viewing conditions, and professional interpretation. Our tools run on your own screen in everyday environments, which makes them useful for awareness and follow-up questions but not for formal diagnosis on their own.

• Screen-dependent: Display calibration, brightness, pixel density, ambient lighting, fatigue, and color-altering settings such as night mode or accessibility filters can change how test stimuli appear.

• Uncontrolled conditions: Unlike a clinical setting, we cannot verify room lighting, viewing distance, monitor quality, or whether browser extensions alter colors during a session.

• Session results only: The site does not require an account to take tests. Results are shown during your session and are not stored as a personal health record. Do not rely on the site to archive results for medical, school, or employment documentation.

• Screening, not certification: Digital results may suggest possible color vision differences, but they do not replace supervised testing with approved equipment for occupational licensing, hiring, or regulatory compliance.

If results seem inconsistent, retake a test in stable lighting with night mode and color filters turned off. For more guidance, see Results and medical use in the FAQs.

• Consult a professional: Always see a licensed optometrist or ophthalmologist for formal evaluation, diagnosis, treatment decisions, and occupational clearance when results are unexpected or symptoms change.

• Not for emergencies: BlindnessTest.com is for educational screening and awareness. If you need urgent care, contact your doctor or local emergency services.

• Children and classrooms: Younger users should take screening with a parent, guardian, or educator. Results for children should be discussed with a qualified eye care professional before drawing conclusions in classroom or home settings.

• Employers and educators: Use the site to teach or demonstrate screening concepts only when you explain that online results are not clinical diagnoses. Do not present the site as a certified clinical instrument without checking your organization's policy and applicable regulations.
