ClinConnect Summary

This clinical trial is studying whether a special type of visual training can help improve distance vision in children aged 6 to 10 who have mild nearsightedness (also called low myopia). The training uses blurry patterns called "Gabor stimuli" on a digital system to help the brain learn to see more clearly without glasses. Children who join the study will be randomly placed into two groups: one group will do this vision training for about three months, while the other group will not. The researchers will also check if the training helps with other aspects of vision, like how well children see contrast, read Chinese characters, and how their eyes move.

To take part, children must be between 6 and 10 years old, have mild nearsightedness (a specific range of prescription), and have normal vision when wearing glasses. They should not be using any typical myopia treatments like special eye drops or contact lenses. Children with other eye problems, like crossed eyes or eye diseases, cannot join. If eligible, families can expect their child to participate in vision tests and the training sessions over a few months. This study is not yet open for enrollment, but it aims to find new ways to help children’s eyesight improve through brain training, not just glasses or medicine.
