Project Title

Myopia Control Effect of Defocus Incorporated Multiple Segments (DIMS) Spectacle Lens in Younger Children with Very Mild Myopia

Synopsis

The global prevalence of myopia has been increasing dramatically for the past few decades, causing an impactful public health concern with significant economic burden in the society. It was predicted that half of the world population will be having myopia and 10% with high myopia by the year 2050. The World Health Organization (WHO) also reported that earlier onset of myopia is being observed in the society.

Most recently, the DIMS lens has gained significant attention among researchers and ophthalmic practitioners as a new myopia control treatment option, following the successful results on children aged between 8 to 13 years old. However, considering the current trend of earlier onset of myopia, there is still lack of evidence on how well DIMS spectacle lenses could work in the younger myopes? Based on a previous study, children at the age of 6 who have less than +0.75D of hyperopia are at increased risk for developing myopia. In the meantime, the younger age of myopia onset is contributing to faster myopic progression which eventually lead to higher myopia in the adulthood. Hence, this project aims to investigate the myopia control effect of DIMS spectacle lens in younger children with very mild myopia.
