| Summary: | With the popularity of various electronic devices and lighting products, the incidence of light-induced retinal damage has surged, which has become a major cause of visual health problems in modern society. A growing number of studies have found that dietary supplementation with nutrients such as anthocyanins, carotenoids, long-chain unsaturated fatty acids and vitamin A is effective in improving vision and enhancing the retina’s resistance to oxidative stress. Therefore, this paper reviews the mechanism of retinal photodamage and discusses the role of different dietary nutrients in improving light-induced retinal injury and the underlying regulatory mechanism. This review can provide a scientific basis for preventing and ameliorating retinal photodamage through dietary supplementation.
