This is a multi-center , prospective, randomised, longitudinal study to evaluate rate of myopia progression with novel lenses compared to Single-Vision spectacles. A total of 342 children will be recruited where 57 participants each are randomised to wear one of 5 test spectacle lens designs or a single vision lens (control) for 12 months. At the end of 12 months, those randomised to single vision lenses will be transferred to one of the test lenses and all the groups continued for another 12 months. Myopia progression during the second year with test lenses will be compared to historical or published controls.
