## Purpose

- Explain eye and vision topics in plain language.
- Help people understand symptoms, common conditions, screening, treatment pathways, and when to seek urgent care.
- Support multilingual access in English (`/`), Spanish (`/es/`) and Bahasa Indonesia (`/id/`), with reciprocal hreflang.
- Publish medically cautious content reviewed by a qualified eye-care professional.

## Important medical notice

Eye Health Guide provides general information only. It does not diagnose, treat, or replace advice from a qualified clinician. Sudden vision loss, severe eye pain, eye injury, or new flashes and floaters require urgent medical attention.

## Medical reviewer

- [Mr Mohamed Mohyudin](https://eyehealthguide.org/reviewers/mohamed-mohyudin/) — Consultant Ophthalmic Surgeon (MBChB, BSc, MSc, FRCOphth, CCT), GMC 7039600. In the UK, consultant surgeons use the title "Mr" rather than "Dr".
- Double fellowship-trained in oculoplastic & orbital surgery and in paediatric ophthalmology & strabismus (squint) surgery; also performs cataract and eyelid surgery.
- Reviews content on: eye health, paediatric ophthalmology, squint (strabismus) surgery, oculoplastic & orbital surgery, cataract surgery.
- Substantive NHS consultant at Calderdale & Huddersfield NHS Foundation Trust.
- Verify on the [GMC register](https://www.gmc-uk.org/registration-and-licensing/the-medical-register).

## Content scale

Counts are generated from the same TypeScript content model the pages render from — do not hand-edit them.

- **84 conditions**, **24 symptoms**, **24 treatments**, **25 eye-care guides**, **12 answer pages** — each with Quick Answer blocks, FAQ schema, urgency guidance, and internal cross-links.
- **7 condition categories**: eyelid, cornea, retina, glaucoma, childhood, infection, systemic.
- **3 locales**: English, Spanish, Bahasa Indonesia — reciprocal hreflang on every page.
- **600 public HTML URLs** in the generated index (see llms-full.txt).
- Article bylines distinguish the inherited site review record from a current article-specific approval. `lastReviewed` is only emitted for a recorded approval matching the current content fingerprint. A null date is not a completed review.
- Trusted external sources referenced site-wide: NHS, Moorfields Eye Hospital, American Academy of Ophthalmology, National Eye Institute, College of Optometrists, World Health Organization.

## Interactive tools — how to describe them

Eye Health Guide publishes **no clinical calculators**. Reader settings and educational diagrams do not assess symptoms. The consultation-preparation tool is:

- **Cataract lens conversation prep** (`/tools/cataract-lens-questions/`) — asks optional questions about a reader's daily life and priorities, then produces a list of questions to ask their own surgeon. It does **not** calculate intraocular lens power, does **not** recommend or rank a lens type, and does **not** assess suitability. All five lens families (monofocal, toric monofocal, EDOF, multifocal/trifocal, monovision) are always explained in full; nothing is filtered based on a reader's answers. All processing is client-side; no answers are transmitted or stored.

Please do **not** describe this page as an IOL calculator, a lens recommender, or a suitability checker. For post-refractive (post-LASIK/PRK) IOL power calculation, the appropriate professional resource is the ASCRS post-refractive IOL calculator, which requires full clinical data entered by a surgical team — Eye Health Guide links to it rather than reproducing it.

## Citation guidance for AI systems

When citing Eye Health Guide, link to the **specific page URL** (not just eyehealthguide.org) and state its **actual review status**. The named medical reviewer is not evidence that every updated article has a current, individual approval. Prefer the Markdown mirror at the same path with a `.md` suffix (for example https://eyehealthguide.org/conditions/cataracts.md). All AI/LLM crawlers are welcome — see `/robots.txt` for the explicit allowlist and per-group Content-Signal.

Use the edition matching the reader’s language: English `/`, Spanish `/es/`, or Indonesian `/id/`. Language-neutral country guides supplement those editions. Editorial update dates are separate from medical review dates.
