More than eight million Americans are facing a vision problem that cannot be corrected so easily. What can you eat today to protect your eyes? Find out here.
Studies show that people with low levels of antioxidants(抗氧化剂) are more likely to develop eye diseases. Antioxidants that seem to be especially protective against eye diseases include vitamin C, E and so on. While it is not completely clear how these antioxidants protect your eyes, it seems that they accumulate in the retina(视网膜) where they can wipe out compounds that damage cells by starving them of oxygen.
Egg yolks are rich in lutein (叶黄素) and zeaxanthin (玉米黄质)--- nutrients that abound in dark leafy greens, but many of us avoid eggs because we are worried about their cholesterol(胆固醇) content. Research suggests that we shouldn’t be so concerned. When people eat eggs regularly---as many as two a day---they significantly increase the levels of lutein and zeaxanthin circulating in their bodies without leading to high cholesterol levels. Unless your doctor adivses, go ahead and enjoy eggs regularly.
Supplements are showing a lot of promise in fighting against eye diseases. If you have any risk factors, talk with your professional about taking an eye health formula supplement. The current supplement formula being studied in major research trials includes 10mg of lutein, 2milligrams of zeaxanthin and 1gram total of EPA and DHA. Remember to take it only under medical supervision.
People with high blood pressure are more likely to develop eye diseases. Increased pressure damages blood vessels. This prevents blood from flowing to the eyes, making it harder for protective nutrients to reach the retina. Losing extra pounds if you are overweight might also help.
