The effect of blue light on ocular health has been studied extensively. Shorter wavelength such as blue light could cause damage to the retina. The damage was more evident in the ageing eye. Since the tablets and mobile with blue LED backlight display are widely used, thus blue-light filtering spectacle lenses are now available in the market. However, whether this kind of lenses could affect the eye growth in schoolchildren is unknown. This study is then designed to investigate if the blue-light filtering spectacle lenses affect myopia progression in Hong Kong Chinese schoolchildren. The schoolchildren will be randomly allocated to either blue-light filtering spectacle lens group (treated) or conventional spectacle lens group (control). Their axial length and refraction will be monitored every 6 months for 2 years. The changes between two group will then be compared.
