How to Improve Eyesight Naturally

Eyes are important for everybody. You must take care and try everything in your hand to keep them in good condition. Here are some of the tips to improve your eyesight naturally.

1. Strain is known to be a factor in many health conditions and eyestrain（眼疲劳） is no exception. Try meditation, yoga or other methods of stress relief to improve your vision and overall health.

Sit upright in a comfortable chair. 2. Cup your hands so that there is no pressure on your eyes. Let your fingers rest across your forehead. There should be no light entering your eyes. Palming（手掌按摩）should be done for a period of 5 to 10 minutes to start. Palming should be relaxing. It may help to do palming in a darkened room.

3. It will unpleasantly affect your eyesight, which affects the eyes by producing a larger amount of insulin (胰岛素) in the blood. Therefore you shouldn’t be having much fruit juice or something that contains a lot of sugar.

The only exercise most eyes get is that daily rubbing we give them when we're tired or suffering from eyestrain. But eye exercises are actually good for your eyes and can improve your vision. 4. Blink as fast as you can for a few seconds then close your eyes tightly, open and repeat. Do this exercise 3 to 4 times daily.

You probably hear that statement all the time but eating the right foods are necessary to good health. 5. Foods that are high in fiber, vitamin C, D and beta carotene as well as other vitamins and minerals can help improve your vision. Here are a few foods that can be beneficial to good vision: carrots, eggs, blueberries, spinach, kale, grapes, and fresh garlic.

A. Reduce eyestrain.

B. Keep your eyes moist（湿的）.

C. Sugar is your eye’s worst enemy.

D. Give your eyes a workout with the following exercise.

E. You may not be aware that your diet affects your vision but it does.

F. Close eyes and cover them with the palms of your hands.

G. Be sure to get plenty of sleep so your eyes don’t strain to stay open during the day.

1.

Sleep, as we know, is important to us because it helps restore tired organs and tissues in our body. But how much sleep do we actually need?

2.

For most of us, eight hours seems to be about the right amount. Yet we know that there are a great many people who get along perfectly with less sleep and some who may even need more. A great deal depends on the way we live. But a good general rule to follow is to sleep as long as we have to in order to feel happy and be able to work at our best when we are awake.

3.

There are actually different levels of sleep. There is a deep sleep and a shallow sleep. In a shallow sleep our body does not get the same kind of rest as it gets in a deep sleep, so that after eight hours of a shallow sleep we may still feel tired. But a short deep sleep can be very restful.

4.

Alexander the Great was able to get a deep sleep whenever he needed it. Once, during the night before an important battle, he remained awake longer than anyone else. Then he wrapped himself in a cloak and lay down on the earth. He slept so deeply that his generals had to wake him three times to give command to attack!

5.

Normally when we go to sleep, our “ sleep center” blocks off nerves so that both our brain and our body go to sleep. One prevents us form wanting to do anything and the other makes our internal organs and limbs go to sleep. But someone will fall asleep (brain sleep) and keep on marching, because his body is not asleep!

Science can't explain the power of pets, but many studies have shown that the company of pets can help lower blood pressure (血压) and raise chances of recovering from a heart attack, reduce loneliness and spread all-round good cheer.

Any owner will tell you how much joy a pet brings. For some, an animal provides more comfort than a husband/wife. A study by Karen Allen of the State University of New York measured stress (紧张) levels and blood pressure in people - half of them pet owners –while they performed 5 minutes of mental arithmetic (算术) or held a hand in ice water. Subjects completed the tasks alone, with a husband/wife, a close friend or with a pet. People with pets did it best. Those tested with their animal friends had smaller change in blood pressure and returned most quickly to baseline heart rates. With pets in the room, people also made fewer math mistakes than when doing in front of other companions. It seems people feel more relaxed around pets, says Allen, who thinks it may be because pets don't judge.

A study reported last fall suggests that having a pet dog not only raises your spirits but may also have an effect on your eating habits. Researchers at Northwestern Memorial Hospital spent a year studying 36 fat people and their equally fat dogs on diet-and-exercise programs; a separate group of 56 people without pets were put on a diet program. On average, people lost about I1 pounds, or 5% of their body weight. Their dogs did even better, losing an average of 12 pounds, more than 15% of their body weight. Dog owners didn't lose any more weight than those without dogs but, say researchers, got more exercise overall-mostly with their dogs - and found it worth doing.

It was a village in India. The people were poor. However, they were not unhappy. After all, their forefathers had lived in the same way for centuries.

Then one day, some visitors from the city arrived. They told the villagers there were some people elsewhere who liked to eat frog’s legs. However, they did not have enough frogs of their own, and so they wanted to buy frogs from other places.

This seemed like money for nothing. There were millions of frogs in the fields around, and they were no use to the villagers. All they had to do was catch them. Agreement was reached, and the children were sent into the fields to catch frogs. Every week a truck arrived to collect the catch and hand over the money. For the first time, the people were able to dream of a better future. But the dream didn’t last long.

The change was hardly noticed at first, but it seemed as if the crops were not doing so well. More worrying was that the children fell ill more often, and, there seemed to be more insects around lately.

The villagers decided that they couldn’t just wait to see the crops failing and the children have to use the money earned to buy pesticides(杀虫剂) and medicines. Soon there was no money left.

Then the people realized what was happening. It was the frog. They hadn’t been useless. They had been doing an important job—eating insects. Now with so many frogs killed, the insects were increasing more rapidly. They were damaging the crops and spreading diseases.

Now, the people are still poor. But in the evenings they sit in the village square and listen to sounds of insects and frogs. These sounds of the night now have a much deeper meaning.

Cleverness is a gift while kindness is a choice. Gifts are easy – they’re given after all. Choices can be hard.

I got the idea to start Amazon 16 years ago. I came across the fact that the Internet usage was growing at 2,300 percent per year. I’d never seen or heard of anything that grew that fast, and the idea of building an online bookstore with millions of titles was very exciting to me. I had just turned 30 years old, and I’d been married for a year. I told my wife MacKenzie that I wanted to quit my job and go to do this crazy thing that probably wouldn’t work since most start-ups don’t, and I wasn’t sure what to expect. MacKenzie told me I should go for it. As a young boy, I’d been a garage inventor. I’d always wanted to be an inventor, and she wanted me to follow my passion.

I was working at a financial firm in New York City with a bunch of very smart people, and I had a brilliant boss that I much admired. I went to my boss and told him I wanted to start a company selling books on the Internet. He took me on a long walk in Central Park, listened carefully to me, and finally said, “That sounds like a really good idea, but it would be an even better idea for someone who didn’t already have a good job.” That logic made some sense to me, and he convinced me to think about it for 48 hours before making a final decision. Seen in that light, it really was a difficult choice, but finally, I decided I had to give it a shot. I didn’t think I’d regret trying and failing. And I suspected I would always be haunted by a decision not to try at all.

After much consideration, I took the less safe path to follow my passion, and I’m proud of that choice. For all of us, in the end, we are our choices.

I believe children have a very pure sense of humor. Well, I would like to share my experiences with you.

The other day when I was out with a friend and her daughter Jane at a restaurant, Jane ordered an apple dessert, which was the most attractive dish in that restaurant. However, when she had a bite of the pie, she shouted loudly, “Mom, why does it look good but tastes like rubber?” My friend was uneasy. Then the waiter gave us another dish.

A child can say funny things. I was at a friend’s home for tea and her son, Mark, wanted her to get up. His mom replied, “I can’t, because my foot has fallen asleep now.” Little Mark then sang a song and asked, “Mom, will it wake up now?” We laughed together.

The other day we were having an interesting conversation over lunch and my friend, an animal activist (积极分子) , was arguing with another group member. Her son Tommy suddenly stood up, “Mom, people should never be allowed to shoot extinct animals!” That was funny and the child did manage to turn the argument into a pleasant conversation.
