Ethnicity is a significant risk factor, with individuals from East and South East Asian countries at greater risk of developing myopia.1 More importantly, myopia begins at an earlier age in these individuals, resulting in a greater number of years during which myopia can progress. This increases the risk that they will develop high myopia.2

Older children are more likely to develop myopia.3 However, annual progression is significantly greater in younger children.4 A 6-year old child with myopia will have significantly greater progression than, for example, a 10-year old, placing them at greater risk of high myopia.

Parental myopia may also influence onset with those with both parents being myopic at greater risk of developing myopia.2

There is also a small difference in prevalence between males and females, with females at greater risk of myopia than males.5
