Virtual Far-sight Reading Device for Myopia Intervention Among Pre-myopic Children

The Virtual Far-sight Reading Device utilizes a birdbath optical configuration and freeform surface technology to extend the working distance from 30 cm to over 6 meters, thereby simulating distance viewing conditions and maintaining ciliary muscle relaxation. Study participants were required to engage in reading and writing tasks using the device for a cumulative daily duration of at least 1 hour.
