People with failing vision often turn to a wide range of methods to make it better. Some will go to optometrists, receive glasses, or get surgery. Others will try natural vision boosting techniques.
Many natural health sources list a litany of supplements such as vitamin C, beta-carotene, and calcium as a proper way to improve your vision quickly and easily. Are these suggestions spot-on or do they make little to no sense?
The truth is, every one of the vitamins he suggested will actually help improve your vision on some level. A study by the National Eye Institute found that people who suffered from age-related macular degeneration (AMD) actually benefited from vitamin C, vitamin E, and beta-carotene doses as high as 500 mg.
However, the study found that the only people who benefited from these vitamins were those with moderate damage to both eyes or advanced damage to one eye. Minor damage or severe damage in both were unaffected by vitamin supplements
Another tactic that seems to have some logic behind it is the idea that exercising your eyes helps strengthen the surrounding muscles. Suggestions such as blinking, palming your eyes, and creating a "figure eight" with your eyes have all been considered ways to improve vision.
The only problem with these methods is that they seem to ignore the reality of how vision problems occur. Almost all of them center on misshaped eyes or damage to their sight apparatus. Warming your eyes with your hands would seemingly do little to help either of these problems. Even worse, many eye exercise programs have been discredited as little more than snake oil, with many companies being sued and forced to sell their product.
A Good Night's Sleep
What about the idea that sleeping can improve your vision? Is this suggestion too good to be true or is there some real science behind it? It appears this may be the strongest natural vision improvement suggestions.
Sleep and vision are highly interrelated: your eyes need at least five hours of sleep every night to repair damage. Any less can cause damage to your eyes and even cause conditions as diverse as light sensitivity, blurred vision, and inflammation of the blood vessels in the eye. That said, there isn't any data to verify whether sleep actually improves vision or just maintains its current health.
Contact a professional optometrist, like those at San Juans Vision Source, to discuss the best health care methods for your eyes.
