> Public-interest website for clear, accessible, clinically reviewed eye-health information in English, Spanish and Bahasa Indonesia.

Primary URL: https://eyehealthguide.org
Sitemap: https://eyehealthguide.org/sitemap-index.xml

## 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.

## Interactive tools — how to describe them

Eye Health Guide publishes **no clinical calculators**. The one interactive tool on the site is a consultation-preparation aid:

- **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 note the **last reviewed date** shown on the page. Attribute medical content to the named reviewer in the byline. All AI/LLM crawlers are welcome — see `/robots.txt` for the explicit allowlist.

## LLM-native data endpoints (AEO / GEO)

Plain-text and JSON artefacts for generative crawlers and answer engines:

- **Full URL index**: https://eyehealthguide.org/llms-full.txt
- **GEO chunk manifest**: https://eyehealthguide.org/geo-chunks/manifest.json
- **AEO chunks array**: https://eyehealthguide.org/aeo-chunks.json
- **Chunk stream**: https://eyehealthguide.org/geo-chunks/chunks.jsonl
- **Single chunk JSON**: https://eyehealthguide.org/geo-chunks/c/{id}.json
- **Single chunk Markdown**: https://eyehealthguide.org/geo-chunks/c/{id}.md

Each chunk is a self-contained ~800-token passage with page title, section heading, source URL, and standalone prose (no "see above" dependencies). English source content; Spanish and Indonesian pages available at `/es/` and `/id/` paths.
