NCT06877494

Brief Summary

The goal of this clinical trial is to test the effect of fish oil supplement in terms of vision in children and adolescents. The main question it aims to answer is: the differences in changes of choroidal thickness, choroidal blood flow, axial length, and visual acuity between the intervention group and the control group Participants will take the fish oil supplement. a baseline examination will be conducted, followed by follow-up visits at 15, 30, and 90 days after the start of the intervention.
