British officers of the era have confirmed that they never worked to deny this claim, but they never actually pushed it as propaganda, and were confident that the Germans knew about their radar technology. Regardless, the claim about carrots being great for improving your vision stuck around.
Carrots do contain Vitamin-A-producing beta-carotene, a vitamin that is good for keeping your eyes healthy, but other foods are much more densely packed with nutrients that can help maintain your vision. Check out these three foods to learn what you can eat to maintain a healthy set of eyes:
SPINACH AND KAL
Many dark, leafy, green vegetables are filled with lutein and zeaxanthin, two nutrients that protect against damage from sunlight, pollution, and other harmful agents. Lutein and zeaxanthin are also believed to absorb harmful rays of light. Spinach and kale carry an abundance of these nutrients — more so than other dark greens.
Salmon, tuna, and sardines are filled with Omega-3 fatty acids. This essential fatty acid supports many functions of your body. Omega-3 fatty acids are known to protect against the formation of macular degeneration and cataracts. You can also ingest this nutrient by taking a fish oil pill, or by consuming flaxseed oil or black currant seed oil, which are also loaded with Omega-3 fatty acids.
ORANGES AND OTHER CITRUS FRUITS
Oranges, grapefruits, and lemons are loaded with Vitamin C, an essential vitamin for repairing and growing tissue throughout your entire body. Vitamin C is linked with prevention of macular degeneration and cataracts. You can find similar benefits in red peppers and strawberries.
Eating healthily is a great step to maintaining your vision, as well as taking care of the rest of your body, but it is not an end-all solution for vision problems. Many eye conditions are genetic or can be caused by factors unpreventable by a healthy diet. Schedule an eye examination with your optometrist if you are concerned about your vision.
