Myopia in Australia

⚠ Measurement methodology note: Unless otherwise stated, prevalence figures on this page use non-cycloplegic screening methods (visual acuity or non-cycloplegic autorefraction). Cycloplegic refraction — the clinical gold standard — typically identifies 10–20 percentage points higher prevalence in school-age children. Figures across countries are not directly comparable due to differing age groups, measurement methods, and study populations. See individual citations for full methodology.

Australia presents a complex and clinically important myopia picture. The broad population has historically lower rates than East Asia, but Australia is home to the world's leading myopia research institutions and some of the most important long-term longitudinal studies. The Sydney Myopia Study is the reference dataset for cycloplegic school-age myopia prevalence in a primarily European-descent population. Crucially, Australian children of East Asian descent in the same environment approach East Asian prevalence rates.

The clinical picture

The Sydney Myopia Study (Rose KA et al., 2008) is one of the best-designed cycloplegic school-based myopia studies globally. Its finding that children who spent more time outdoors had significantly lower myopia rates — independent of near-work — provided strong evidence for the outdoor light hypothesis. Australian outdoor lifestyle has been proposed as a key reason why European-descent Australian rates are lower than European children in comparable academic environments.

The outdoor light evidence: Rose KA et al. (Ophthalmology 2008) showed that children spending more time outdoors had substantially lower myopia rates. The mechanism is proposed to be retinal dopamine release triggered by high-intensity outdoor light (10,000–100,000 lux), which suppresses axial elongation — an effect not replicated by indoor light even at high indoor levels.

Research leadership

The Brien Holden Vision Institute (BHVI) in Sydney is one of the world's most important myopia research organisations, having contributed to the development of orthokeratology lens designs and conducted foundational work on the epidemiology and mechanisms of myopia. The Sydney Myopia Study and the Multi-University Centre Study (MUCS) are among the most cited longitudinal paediatric myopia datasets globally.
