visual acuity of 20/20 is frequently described as meaning that a person can see detail from 20 feet away the same as a person with normal eyesight would see from 20 feet. If a person has a visual acuity of 20/40, he is said to see detail from 20 feet away the same as a person with normal eyesight would see it from 40 feet away.
It is possible to have vision superior to 20/20: the maximum acuity of the human eye without visual aids (such as binoculars) is generally thought to be around 20/10 (6/3). Recent developments in optometry have resulted in corrective lenses conferring upon the wearer a vision of up to 20/10. Some birds, such as hawks, are believed to have an acuity of around 20/2, which by definition, is much better than human eyesight.

If you have vision problems there are several systems to fix it
To know how to do that you can discover here a compelte technique focused around researches
http://improvevision.toptips.org
I can provide for you simply a few tips however I recommend to give a look to the technique that i posted above...for illustration you can take more sustenance that holds vitamin A, for example, carrots may help to naturally improve your vision. We can likewise dependably do exercises. There are exercises, for example, rolling your eyeball to form an undetectable square that are constantly recommended by the doctors to improve one's vision. I don't think about rapidly as there is no quick approach to reach one's objective.
Vegetarians can help to improve one's vision. I accept it in light of the fact that I am a vegetarian and my eye short-sightedness power remains the same without any increase after around 2 years. The doctor was stunned in light of the fact that teenagers at my years will normally have a most increase since we are continually staring at the TV, playing computers furthermore reading. I don't know whether it is completely true or not yet it does influence a bit on the result.
At any rate i propose to check the connection that i posted :) It worked for me

20/20 is the average vision for people without eye disease. Some people have eyes that can see better than 20/20. If the doctor said you have 20/20 but could use glasses for driving, then you would see better than 20/20 with the glasses.

There's certain vitamins that you can take that are good for eye health. If you don't feel right taking those...try to get good sleep at night, don't strain your eyes by reading in the dark or staring at computer screens for long. Sometimes you just can't help losing perfect vision. It can deteriorate with age

Yes that is perfect vision, you are very lucky. There are no real ways to maintain it, just look after your eyes by wearing sunglasses and maintain a healthy and active lifestyle.

It is perfect. Unfortunately unless you can find something to stop the ageing process it will tend to deteriorate as you get older.
Enjoy it while you are young. Speaking as a chap with bifocals who still can't manage the fine print, its a pain!

there's no way to actually maintain perfection vision (which you have), but according to research watching too many screens (i. computer, tv) doesn't help at all.

20/20 is not perfect vision. The Australian aboriginals have 80/20 eyesight, which means they can see the moons of Jupiter and the rings of Saturn with their naked eyes, and also read up close very well. When eye doctors tell people they have "eagle eyes" that refers to having better than 20/20 vision. Even the Greeks knew that Saturn had rings, and telescopes weren't "invented" until Galileo's time. citation: http://www.varchive.org/itb/rings.htm (there are two paragraphs that show:
"The rings of Saturn were known also to the aboriginees of America before Columbus discovered the land; this means also before the telescope was invented at the beginning of the seventeenth century. An ancient engraved wooden panel from Mexico shows the family of the planets: one of them is Saturn, easily recognizable by its rings.(10)
*Nor were the Maoris of New Zealand ignorant of them: “One of the great mysteries connected with Saturn is the still unanswered question of how the ancient Maoris of New Zealand knew about her rings—for there is evidence that they did have a Saturnian ring legend long before the days of Galileo.” (11) "
There's also a misconception going around western society about how the eye really works. This affects our optometrists. I know what I'm about to show you is long, but I think it'll be worth your time to read it... if you don't believe what I'm saying, that's fine. There are a number of things that most people don't know even up until the day they die, about misperceptions regarding vision - that can possibly change your life because good vision is attributed to quality of life.
"I've experienced vision improvement firsthand. My vision used to be L: 3/20 R: 4/20 but now I have an average vision of L: 7/20 R: 10/20, after only a month.
Go to http://www.iblindness.org/ and learn about the Bates Method. Also important: read and/or post at the forums at http://www.iblindness.org/forum/
There are many things you can do to help your vision, but they are not the same as the misleading commercialized 'eye exercise packages' out there. I strongly recommend starting with this book called "Relearning to See" which you can get at Amazon.com through this link: http://www.amazon.com/Relearning-See-Improve-Eyesight-Naturally/dp/1556433417/sr=8-1/qid=1171080842/ref=pd_bbs_sr_1/103-8926485-6989404?ie=UTF8&s=books
Out of the 24 reviews on this book, each single review has received 5/5 stars.
Many people have only seen one side of the coin, not both. They have not experienced a paradigm shift in understanding how western society has been affected by misinformation on some levels.
I tried convincing my cousin about the need to separate the mind from the body. Vision is largely a mental process. For many years, psychologists have tried to emphasize that thoughts and emotions are capable of causing MOST diseases of the body to manifest in a physical sense. There is a strong bias in the medical community that makes it favor attack-the-symptom, drug-based medicine. Since the method I'm referring to involves quite a bit of psychology, it may be dismissed by some out of hand. [Western medical] "Doctors" do not deal with psychology. Now, what if vision problems are actually a disease caused by the mind? (I have overwhelming evidence that can support this)
It may not make sense to you until you read more about it, so I strongly suggest you read up about it. There has been very clear evidence revealed in the British Medical Journal of how western scientists have distorted things, giving people the mistaken impression the scientists, including optometrists, are on top of everything--but they aren't... citation: http://www.bmj.com/cgi/eletters/326/7404/1407 (go down to where it says "The fallacy of an assumption of simplicity" and you have one of the most convincing articles ever presented on the problems regarding the western mindset. This is a cultural thing...)
I tried to convince my cousin of this, but his inability to "see outside the box" posed a serious problem. You may be familiar with paradigm shift of how a single image can be interpreted two different ways: http://en.wikipedia.org/wiki/Image:Duck-Rabbit_illusion.jpg -- this is an example of a paradigm shift viewpoint. A person may only be able to see the duck or the rabbit in that picture, while another person can see both the duck and the rabbit. I can see both the "duck and rabbit", metaphorically speaking, but my cousin can't, and neither can many people, including doctors and ODs. They are still prone to assumptions that everything they've taught has been sufficiently backed up. May be true in many cases, but for the optometrists, there is a serious problem.
I commented as I showed a few people what had gone wrong when I tried convincing my cousin: "It's too bad he thinks our scientists and optometrists are smart enough to find out whatever has gone wrong, although I gave him direct evidence indicating otherwise (Helmholtz's Theory of Accommodation reference at Wikipedia, for example). This should've been a "hint" to him that scientists aren't always one step ahead on everything. One detail overlooked, especially if it has to do with something right at the optometry foundation, and just about anything is suspect to potential flaws. It seems that Helmholtz's Theory was treated the way a cold case would be in a criminal investigation, closed from further investigation due to "limited manpower" and resources and interest. Then no one but Bates checked into it. It's amazing how some people are unable to think outside the limits they have imposed on themselves.."
That is why things like improving vision are easily dismissed out-of-hand by many people- including doctors. But it does make sense from a true scientific perspective. Ex. the brain flips the retina's image (which is upside down) the right way down shortly after we are born. We also have optical illusions, that are attributed to the mind. For eye doctors to address the eye as a physical-only organism is based on many misconceptions... you need to read more if you wish to understand how this has happened to society. Dismissing this possibility out-of-hand would be based on assumptions. A person needs to read closely both sides and understand what's going on before making a judgment.
Many people don't understand that there are different ways of seeing things, and that certain things make sense only if you take for granted certain underlying premises, which people don't always see alternatives to.
Anyway, I suggest you check out the sites I provided. Especially the first two. There are a lot of misconceptions about eye exercises out there, and what other people may offer you may give temporary results but not permanent results. What part of your body do you move more than any other? Your eyes. Why would you need to exercise them any more? They're fatigued and causing strain in the mind... this is opposite of what many 'eye exercises' products out there say, and what I'm showing you has a history to it and is based on the discovery of a very brilliant, well-respected scientist that got ostracized as soon as he made a nearly 180 degree turn after 25 years as an optometrist. He discovered there was a very bad, inconclusive mistake at the foundation of optometry understanding of how the eye works. Don't assume that modern advancements have addressed the real problem, there are many unexplainable (or explained away) ideas about what causes diseases of the eye."
