CATHAY ExtDOT Spectacle Lenses for Reducing Myopia in Chinese Children

This study aims to assess the safety and effectiveness of special glasses called Diffusion Optics Technology (DOT) spectacle lenses in slowing down the worsening of nearsightedness, or myopia, in children of Chinese descent. Myopia is a common vision problem where distant objects appear blurry, and it often worsens during childhood. The study is important because finding a way to slow down myopia progression can help prevent more severe vision problems later in life. Participants in this study will be randomly assigned to use the DOT spectacle lenses over a 12-month period. The study is open-label, meaning participants and researchers will know who is receiving the DOT lenses. However, the evaluators, who measure the outcomes, will not know who is wearing the lenses to ensure unbiased results. The study will take place at multiple centers, with regular check-ups to monitor children's eye health and measure changes in their vision. The main focus is to gather more information on the long-term safety and benefits of using these lenses in managing myopia in children.
