20 40 Vision Need Glasses

What Does 20 40 Vision Mean

How to get 20/20 vision without eye glasses or surgery

Youre probably already familiar with the term 20/20 vision. Many people believe this means your vision is perfect, but that isnt actually the case. Someone with 20/20 vision doesnt have razor-sharp vision, but sees things at 20 feet that most people who dont need vision correction see at 20 feet. Hence the vision of 20/20.

A person with 20/40 vision sees things at 20 feet that most people who dont need vision correction can see at 40 feet. This means that they are nearsighted, but only slightly. 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. In this case, the person has what is known as low visual impairment.

Do People With 20/40 Vision Need Glasses

When you are diagnosed with 20/40 vision, this means you are slightly nearsighted. You have a harder time seeing items farther away than people with 20/20 or 20/10 vision. For example, reading road signs can be more difficult, especially if the font is smaller. But does this mean you need glasses?

One of the indicators that people need glasses is driving. To get your drivers license, you must pass an eye exam. According to the American Academy of Ophthalmology, most states will issue a drivers license to those with 20/40 vision. This means those who are slightly nearsighted may not need corrective lenses to drive.

Even though it may not be legally required to wear glasses to drive, many of those with slight nearsightedness prefer to wear glasses or contacts. It can be easier to see things farther away, which can be important in many professions, leisure activities and for personal vision enjoyment.

Le " Yeah, I have 20/40 vision, but I don

Depending on the state of your eye health and vision, most eye doctors strive to give eyeglasses to individuals that correct their vision to 20/20. This is the perfect score that enables most people to see clearly.

However, your vision may be so bad that the doctor is only able to correct your vision to say 20/70. Someone who is legally blind, however, can only have their acuity corrected to 20/200.

How Is 20/60 Vision Measured

The Snellen acuity chart is the traditional chart of large and small letters, referred to as optotypes in this context. The chart is made up of 11 lines of block letters, with the top row starting with a huge single letter. As you go from top to bottom, the number of letters on each row increases. The letters gradually shrink in size, providing for more letters on each succeeding line.

When assessing visual acuity, the patient closes an eye and reads the letters on the chart from top to bottom, starting at the top and working down. Visual acuity in the uncovered eye is determined by the lowest row of letters that the patient correctly reads. The test is performed with the opposite eye, and then both eyes at the same time.

The quality of your vision will be determined by the results of your acuity test . The findings of your eyesight will be presented as a fraction. Each row has fractions to the left of it that indicate how well that you see.

If you are able to get the letters to the fifth line, for instance, your vision would be described as 20/40 if you could read all the way to the seventh line, it would be described as 20/25.Consider the figures in feet while interpreting your reading. A person with 20/60 vision, for example, can read at 20 feet what someone with normal vision might see at 60 feet.

How Does An Eye Doctor Determine If I Have 20/40 Vision

If you go to an appointment with an eye doctor, or sometimes at a clinic where you may have a physical, youll likely have an eye test to measure your visual acuity. During the eye test, youll read the letters on an eye chart, known as the Snellen Eye Test.

How far down you can read on the eye chart, with and without vision correction, will determine what the ratio your eye doctor will give.

This ration will also help determine what prescription you need, if any. Your doctor can also note your visual decline or progress over a period of time. This is especially important for those who have certain conditions that affect the eye, or if they have had LASIK or cataract surgery.

Your doctor may also test your eyes with something called a phoropter. He or she will place this in front of your eyes and switch different lenses in front of them to determine which prescription is best for you.

Is It Possible To Still Need Glasses Even With 20/20 Vision

So now that we have a basic understanding of the 20/20 measurement, is it possible to still need glasses even with 20/20 vision? Well, glasses are needed for a variety of reasons. Excluding sunglasses, people with dyslexia and astigmatism may require prescription glasses. There are also special glasses with high definition lenses to give people with 20/20 vision even better focus.

The more important question is if you need better than 20/20 vision, and for what purpose. A sports athlete may not care about how much his eyes focus, but more about the speed at which they can discern information, for fast-moving objects. This can also change for different coloured objects and how an artist or painter interacts with them. Acuity is not the only measurement that matters, and its not reflective of your vision in other circumstances.

So can you still need glasses and have 20/20 vision? Of course, depending on your situation and what you want to accomplish. Getting a regular checkup at your optometrist should be a part of everyones life, and can not only help your vision but help detect and prevent eye disorders.

Life With 20/40 Vision

A 20/40 score is not perfect. Other people have better visual acuity than you do. But this is not the worst possible score. You might find you can live with this score even if you never have it corrected or amended.

The American Academy of Ophthalmology reports that people in most states can drive without glasses or contacts with a 20/40 test result. You may not see road signs as clearly as someone with 20/20 vision, but you are still considered a safe driver with this score.

But even so, a score of 20/40 can make some activities difficult. As the Centre for Vision in the Developing World points out, a 20/40 score can make reading text on a blackboard tough. You might also find it hard to:

  • Watch movies with subtitles.
  • Read a menu posted on the wall of your favorite coffee shop.
  • See tiny type on a recipe as you cook.
  • Discern flight details at the airport.

For some people, these issues are mildly annoying. For others, they are deal-breakers.

/20 Vision 20/10 Vision 20/40 Vision What Do All These Numbers Actually Mean

Optometrists and ophthalmologists around the world, have discovered the standard by which every person should be judged, when diagnosing their vision status. 20/20 vision is referred to as the standard, or how a normal person sees. This means, that when you stand 20 feet away from an eye chart, you see what the normal person should see. The American Optometric Association states that a person with 20/20 vision can clearly identify a row of 9mm letters from 20 feet.

Did you know that to be considered legally blind in the U.S., your vision is as bad as 20/200? A legally blind person with vision of 20/200 has to be as close as 20 feet to identify objects that people with normal vision can spot from 200 feet. So a legally blind person needs a distance of two feet to spot the letters on a standard eye chart that is 20 feet away.*

So if you have 20/40 vision, this means that you can see only as good as a normal person can see at 40 feet away from an eye chart. To clarify this further, if you have 20/40 vision, and there is a normal person standing 40 feet from the chart and you are standing 20 feet from the chart, you both see the same amount of detail on the eye chart.
