OpenEvidence Snapshots
Bridge research and practice.
10 one-minute reads from IMI, TFOS DEWS III, LAMP-2, and LiGHT — with Singapore clinical takeaways and patient scripts.
High myopia (≥ −6.00 D) triples open-angle glaucoma risk — with 940 million high myopes projected by 2050, East Asia faces a compounding epidemic within one generation.
1 min readTFOS DEWS III (2025) redefines dry eye around three driver subtypes — and recommends just two diagnostic tests for standard optometry settings.
1 min readSingapore's School Myopia Programme cut P1 prevalence from ~34% (2000) to ~26% (2023) — structured outdoor time and early atropine work at population scale.
1 min readReference Hub
Quick-access tables for the consultation.
Normative values, medication awareness tables, and systemic health benchmarks — calibrated to Singapore scope and structured for fast lookup mid-consult.
Binocular Vision

Built by clinicians, for clinicians.
Optometry Hub is written and reviewed by practising optometrists with reference to Singapore's scope of practice. Clinical pathways are developed against published international guidelines — including IMI, TFOS DEWS II, and EGS — and cross-checked against local MOH advisory standards before publication.
