The high prevalence and early onset of myopia in Chinese children—a major public health concern—has created a dedicated segment for nutritional support aimed at potentially attenuating its progression. While the primary, most effective clinical interventions remain atropine and specialized optical devices, nutritional supplementation is widely utilized as a complementary preventative strategy.

Research in this area often focuses on compounds that support the structural integrity and healthy growth of the eye, notably Omega-3 Polyunsaturated Fatty Acids (PUFAs), particularly DHA and EPA. These nutrients are investigated for their potential to influence the scleral and choroidal tissues. Preclinical studies suggest that Omega-3 PUFAs may inhibit myopia development by improving choroidal blood perfusion (ChBP) and regulating key biological pathways that control axial length elongation of the eyeball. Other compounds, such as certain antioxidant carotenoids, are also commonly included to protect retinal tissues from the visual stress of intense near-work and digital screen exposure. This research-intensive focus on preventing the national pediatric vision crisis underscores a unique and critical area within the overall supplement landscape, as detailed in specialized health sector reports like the China Eye Health Supplements Market Analysis.
