The association between macronutrients intake and myopia risk: a systematic review and meta-analysis.

Background: Dietary factors have been suggested as potential risk factors for myopia, but research findings on this relationship are inconclusive. The potential predisposing or protective role of macronutrient (carbohydrate, protein, fat) intake in the development of myopia was systematically reviewed, followed by data synthesis by meta-analysis.

Methods: A systematic search was conducted in PubMed, Web of Science, Scopus, and Google Scholar up to the end of June 2023 to identify all relevant studies.
