福利大放送——眼操改善老人视力
The process of aging is of particular concern for Americans. This concern is not only related to the likelihood of increasing your chances of coming down with diseases such as heart disease and diabetes, but more importantly, to concerns about losing your eyesight. As we get older, the chances that we will develop age-related vision conditions and disorders increase.
Therefore, many people believe that it’s very hard, if possible, to improve your vision naturally as you get older due to concerns that the visual system begins to deteriorate at that stage of life. These people also believe they’re stuck with their glasses or contacts for life. So the question is: can aging prevent you from improving your vision naturally?
The answer to that question is “No”. While aging is inevitable, when it comes to improving, protecting and preserving your precious eyesight, there are things you can do to reduce or slow the negative effects of aging on the visual system. For instance, you can take preventive steps in terms of nutrition and eye exercises that can reduce the negative effects of aging on the eyes.
These simple and easy to perform techniques make the visual system stronger, therefore helping you to improve your vision. They also improve the focusing power of the eyes through vision training eye exercise techniques. Additionally, eye exercises can improve blood flow and circulation to the visual system, therefore improving your eyesight. The question is: can these eye exercises help improve vision even in older people? Well, the answer to this question is “Yes”.
According to a scientific study performed by the National Institute on Aging, elderly adults can quickly improve their vision with a type of eye exercises called Perceptual(知觉的) Training. Perceptual Training relates to the ability to improve various visual skills by exposing a person repeatedly to activities involving all kinds of stimuli(刺激). This improves the way the brain processes visual information by strengthening the connection between the brain and eyes.
