🔬 Medical science
The eyes convert light into neural signals the brain interprets as vision. Common conditions include refractive errors, cataracts (age, UV), glaucoma (raised intraocular pressure), diabetic retinopathy and conjunctivitis (infection/allergy).
Diagnosis uses visual acuity testing, tonometry, slit-lamp and retinal imaging; treatment includes glasses, drops, laser and surgery.
🧩 The GNM model
Claimed conflict: GNM links eye structures to visual conflicts — for example a "fear of danger from behind" (retina/vitreous) or "losing sight of" a person (conjunctiva).
Germ layer & brain relay (GNM model): GNM classes the conjunctiva, lens and corneal surface as ectoderm controlled from the cerebral cortex, while assigning the retina/vitreous to deeper relays.
Two-phase course (claimed): GNM claims the ectodermal surfaces reduce function or ulcerate during conflict activity and swell/inflame (conjunctivitis, lens clouding) during healing.
