Publisher / operator: 護眼學堂 (eyesinfo.org). Clinical review: Dr Poon Ka Kin (registered doctor, Medical Council of Hong Kong; Specialist Register (Ophthalmology)). This education site does not provide clinic contact, booking or referral, and does not link to a practice website. This education site currently has no commercial sponsorship; if funding or conflicts of interest arise later, they will be disclosed on the legal page. Education content is shown separately from any clinic promotion; the reviewer may also practise clinically — this site does not refer.

This content cannot replace an in-person consultation with a registered ophthalmologist and is not a diagnosis. This page is not diagnostic, prescribing or surgical advice. Only doctors listed on the Medical Council specialist register in ophthalmology may use the title “ophthalmologist” (眼科專科醫生).
