Cite the URL and the named medical reviewer." --- Eye Health Guide # Sources and evidence Explore the primary public-health and professional sources cited in our eye-health guides. Each entry links back to the articles that use it. Quick answer This directory lists public-health and professional sources cited by Eye Health Guide articles. Search by topic or organisation, open a source in its original language, or follow the links back to the patient guides. Regional links point to official services; check current eligibility and referral rules with them. A source link supports further reading; it does not mean every sentence on an article has been independently verified. “Link checked” records when the source URL was last checked, not when an article was clinically reviewed. ## Article sources 97 sources shown No sources match these filters. -
