What is “Perfect” Vision? While 20/20 vision is considered to be perfect, it's not actually what we think of as perfect. Many people, mostly children, have better than 20/20 vision. Healthy eyes can easily go down to the 20/15 level with some accuracy.
Can people have better than 20/20 vision? 20/10 vision is thought to be the maximum visual acuity of human eyes without binoculars or other magnifying devices. Recent advances in optics have led to the creation of corrective lenses that can provide this ultra-sharp vision.
If you have 20/10 vision you are above average! You are better than the “normal” person and you have better than what is considered to be standard or normal, vision. If you have 20/10 vision, you can see at 20 feet, what a normal person can see at 10 feet from an eye chart.
Having a 20/20 vision doesn't mean you have the best or perfect vision. It's only a common baseline to determine normal vision. Having something like 20/13 vision is better since it means you can see 20 feet clearly while the average can only see 13.
Eagles – Best Eyes in the Animal Kingdom
To put that into perspective, an eagle has the visual acuity of 20/5 – meaning that it can see at 20 feet what a human with 20/20 vision would need to be 5 feet away from to see. By this standard, an eagle's visual acuity is 4 times stronger than ours.
Most people don't have 20/20 vision without eyeglasses or contact lenses. One estimate suggests that only about 35% of all adults in the U.S. have 20/20 vision without corrective lenses.
If you have 20/10 vision, you can see details at 20 feet that people with normal vision can only see at a distance of 10 feet. It is a rare level of visual acuity, with less than 1 percent of people achieving it.
20/25 vision is not bad. It's just weaker than someone with normal vision. The World Health Organization puts 20/25 visions in the same category as 20/20. It means that people with 20/25 vision can see almost as clearly as those with normal eyesight.
For example, if you have 20/30 vision, it means your vision is worse than average. Twenty feet away, you can read letters most people see from 30 feet. A standard Snellen vision testing chart.
If you have better vision than 20/20 for example 20/16 it means that you can see at twenty feet what an average person can only see at sixteen feet and of course the opposite if you are 20/40, for example, it means you have poorer vision than an average person; you see at twenty feet what they see at forty feet from ...
In order to be legally blind, you must have a visual acuity of 20/200. This means that even with glasses or contacts, you can only read the first letter at the top of the Snellen Chart, if that. You can also be legally blind if you can see, but only in a very small window in your eye.
A score of 20/5 means you can see things at 20 feet most people can't see until they are standing 5 feet away. This type of visual acuity is akin to an eagle's vision. There have been reports of an Aborigine man who had 20/5 vision. Despite this, researchers believe this level of vision is not possible in humans.
Some age-related vision changes can be corrected with surgery, glasses or contacts. You can also keep your eyesight sharp by taking care of your health before serious problems begin. Some simple exercises can even keep your vision healthy.

Having 20/25 vision means your eyesight is slightly outside the range of normal vision (20/20). Although 20/25 vision isn't bad, it's not as good as 20/20 vision or normal visual acuity. You may need corrective lenses with a low prescription. Eye doctors will look at other aspects to determine how well you see.
A person with 20/40 vision may or may not need eyeglasses or contacts, and can discuss his or her options with a doctor. In some cases, people with very bad vision can only have their vision corrected to 20/70, meaning they can see objects from 20 feet away that others can see at 70 feet.
The numbers in your visual acuity measurement have to do with distance. It might be easiest to explain if you imagine the Snellen chart: When you have a Snellen test score of 20/40, that means you'd see the chart as clearly at 20 feet away as someone with “normal” vision would see it from 40 feet away.
Glasses and 20/30 Vision
With 20/30 vision, the level of visual acuity is considered to be within the normal range. Not surprisingly, many people with 30/30 vision are able to see well enough to live without glasses or contacts.
It depends on your overall vision. According to the American Optometric Association, the following levels of vision can indicate an issue that requires corrective eyewear: 20/30 to 20/60: This means you may have a small vision issue, but your vision is almost normal.

Eagles are thought to have the best eyesight of all; their eyes are as many as eight times sharper than ours. We don't do too badly either. Our vision is four to seven times as sharp as those of cats and dogs and 100 times sharper than that of a mouse or fruit fly!
Eagles. All birds of prey have excellent long-distance vision, but eagles stand out. They can see clearly about eight times as far as humans can, allowing them to spot and focus in on a rabbit or other animal at a distance of about two miles.
What is the rarest eye color? Green is the rarest eye color in the world, with only 2% of the world's population (and fewer than one out of ten Americans) sporting green peepers, according to the American Academy of Ophthalmology (AAO).
