Influence of Rodenstock Spectacle Lenses on Myopia Progression.

The prevalence of myopia in Singapore is among the highest in the world, with 65 percent of our children being myopic by Primary 6, and 83 percent of young adults being myopic. As such, Singapore is often labelled as the "Myopia Capital of the World". By 2050, it is projected that 80 to 90 per cent of all Singaporean adults above 18 years old will be myopic and 15 to 25 percent of these individuals may have high myopia. High myopia (spherical equivalent refraction ≤ -5 D) puts one at risk of many eye disorders later in life, such as early cataracts, glaucoma and macular degeneration. These complications often cause significant morbidity and may even be sight-threatening. Hence there is an urgent and growing need for synergistic efforts to counter myopia. The goal of this clinical trial is to test the efficacy of spectacle lenses in controlling the progression of myopia in children (age
