If you are in the sun frequently and have low antioxidants you have an increased risk of advanced macular degeneration
A recent study from Europe found that having reduced plasma antioxidant levels and increased exposure to the blue spectrum of sunlight puts one at a greater risk of neovascular, or advanced age-related macular degeneration.
The study included 4,400 participants in the European Eye Study. Subjects underwent fundus (the back of the eye; the retina, vessels and the optic disc) photography to evaluate the presence of macular degeneration, and blood plasma was analyzed for vitamins C and E, the carotenoids Lutein and Zeaxanthin, and the mineral zinc. Questionnaire responses concerning sunlight exposure were used to estimate blue light exposure from visible light, which has been shown in laboratory studies to contribute to the development of macular degeneration.
