Abstract: With the popularity of electronic devices (e.g. mobile phones, tablets, computers, etc.) and various lighting products, the incidence of visual light-induced retinal damage has increased dramatically, becoming a major cause of visual health hazards 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 work reviews the mechanisms of retinal photodamage and, on this basis, discusses the role of different dietary nutrients in improving visible light-induced retinal injury and the corresponding regulatory mechanisms. This review can provide scientific basis for preventing and ameliorating retinal photodamage through dietary supplementation.

Key words: retinal, oxidative stress, anthocyanins, carotenoids, dietary nutrition
