Sponsor's own description

The purpose of this study is to evaluate whether bifocal soft contact lenses (CLs) with low addition and nasally decentered optical zone are effective in controlling myopic progression in children. Visual manipulations induced by multifocal soft CLs with high addition have been shown to inhibit eye growth and myopia development in children by recent studies. Several theories have been proposed including alteration in peripheral defocus, reduced accommodation demand, alterations in binocular vision status and increased ocular higher order aberrations. However, those theories remain to be proven and the optical properties and performance of multifocal soft CLs have not been investigated in children.
