Color Vision Check is an educational screening tool. It is not a medical device and does not diagnose, treat, cure, or prevent any medical condition. Consult a qualified eye-care professional for medical advice, diagnosis, or treatment. If a color-vision change is new, sudden, one-sided, or concerning, seek professional care.
