Editorial & Medical Content Policy

Purpose and scope

ColorVision publishes educational information about colour vision deficiency and provides browser-based screening activities. Our content is intended to explain concepts and help users understand the limits of online screening; it does not provide a diagnosis, treatment recommendation, or individual medical advice.

How content is prepared

The ColorVision Editorial Team prepares and maintains the site’s educational content. We aim to use primary research, government health information, and established clinical references for factual claims. Where a page draws on a specific source, we link to it directly so readers can review the evidence.

Medical boundaries

Online colour tests can be affected by display calibration, lighting, browser settings, visual acuity, and testing conditions. They must not be used for medical, licensing, employment, or legal decisions. For symptoms, a newly noticed change in colour vision, or a result that concerns you, consult a qualified optometrist or ophthalmologist.

Updates and corrections

We review educational pages when material information changes and correct substantiated errors. Each article displays its publication date, and pages with substantive revisions will show an updated date. To report a factual or accessibility concern, use our contact page.

Authorship and clinical review

Articles currently attributed to the ColorVision Editorial Team are prepared and maintained internally. That byline does not represent a medical qualification. No page should be treated as reviewed by an optometrist, ophthalmologist, or other licensed clinician unless it names that reviewer and gives a review date. We do not add a reviewer to a byline or to structured data without a real, documented review.

Translation and indexing policy

English is the source language. Locale-prefixed pages may remain available for visitors while they are excluded from search indexing. A translated locale is eligible for indexing only after a native-language reviewer checks visible copy, medical terminology, result wording, links, metadata, structured data, and legal pages. The release record must also state how the translation was produced, including any machine-translation or AI assistance. ColorVision does not currently present any non-English locale as having completed that review.

Review record required for future languages

• Reviewer’s real name, language competence, role, and review date
• Routes and content version reviewed
• Corrections to terminology, safety language, links, and metadata
• Confirmation that no English fallback or mixed-language copy remains
