Health experts warn of rising vitamin D deficiency and childhood myopia

Medical experts are highlighting significant public health concerns regarding vitamin D deficiency and the rising prevalence of myopia. Dr. Michael Holick from Boston University notes that approximately 60 percent of the global population does not consume sufficient vitamin D. Despite being known as the “sun vitamin,” deficiencies can occur even in summer due to factors such as diet, skin pigmentation, age, and increased time spent indoors. While UVB rays stimulate production, factors like cloud cover, pollution, and the use of sunscreen can limit absorption.

Simultaneously, health professionals are addressing the surge in childhood myopia, or nearsightedness. Projections suggest that nearly 50 percent of the global population could be myopic by 2050. Dr. Kimberley Chan, an optometrist, emphasizes that while genetics play a role, environmental factors—specifically the amount of time children spend outdoors and their near-vision habits—are critical. Managing myopia in childhood is essential to prevent severe long-term complications such as retinal detachment, glaucoma, and macular pathology.
