What Does 20 50 Vision Mean? Is 20/50 Vision Bad?

what does 20 50 vision mean

A 20/50 is a vision type that falls into the category of mildly bad vision.

If both eyes have 20/50 vision, you need glasses or contact lenses.

Let us discuss in this article what the 20/50 vision is.

20/50 Vision Explained

When you have 20/50 vision, you can see at 20 feet what a person with normal vision can see from a distance of 50 feet.

If you compare yourself to people who can see 50 feet away, you need to be 30 feet closer to see the same thing.

When it comes to vision, the term “20/20 vision” is always discussed.

Many people assume that the “20/20 vision” is the perfect vision, but this is not true.

20/20 vision describes the normal eyesight range, not the perfect eyesight range!

It is possible to have better vision than 20/20, like 20/15 or 20/10.

According to the American Optometric Association, the WHO classified 20/30 to 20/60 vision range as mild vision loss.

The WHO uses a classification chart for identifying visually impaired people.

Those between 20/70 and 20/160 have moderately low vision.

Having a vision of 20/200 or worse would consider you legally blind.

If you have this vision, you must wear contacts or eyeglasses.

If a person cannot see at six meters what someone with normal vision can see at sixty meters, they are legally blind.

Is Having A 20/50 Vision Bad?

20/50 finished is not bad.

But it is also not a good vision.

Having a 20/50 vision means that you are slightly nearsighted.

You have the option to wear refractive aids, but it is not required.

This can be easily corrected by using eyeglasses.

People who reach 20/70 vision are the ones who should get eyeglasses or contact lenses.

Does That Mean I Have To Wear Glasses?

Glasses are optional for people who have 20/50 vision.

If you are not having problems with your vision, then you can probably go on without needing glasses.

Normally, a person has a dominant eye where their vision is slightly better.

If you have an eye with 20/50 vision on only 1 eye, you don’t need glasses.

However, a 20/50 vision with both eyes open is not good.

Your sight could interfere at certain times in your life.

Some jobs also require you to have a vision of around 20/20.

If you are unsure what to do, we recommend visiting an ophthalmologist.

Some eyes will not reach 20/20 vision even when using eyeglasses.

However, having a vision close to 20/20 is still better than having a bad vision.

There is unconfirmed information that wearing glasses will make your vision worse.

Due to the adaptive capabilities of our eyes, this rumor might be true.

Long time exposure to using correction lenses might cause your eye to adapt to the same visual field.

And so, when you remove your glasses, you will notice that your vision has become worse.

How To Test My Eyesight?

How To Test My Eyesight

A Snellen Eye Chart is used by eye practitioners to test their eyesight.

It was invented by Herman Snellen back in 1862.

He was a Dutch ophthalmologist.

These eye charts assess a person’s visual Acuity.

It helps eye doctors prescribe corrective lenses and correct vision.

The tumbling “E” Snellen Chart is used for children who can’t read.

How to Check Your Patient’s Visual Acuity

What is Visual Acuity?

Visual Acuity talks about how much your eye can see 20 feet away.

It talks about your vision’s “focus” and “sharpness”.

In the Snellen Chart, if you can read the small letters at the bottom, then that means your vision is good.

If you can only read the big letters above, your vision is bad.

These numbers on the right indicate the distance.

The further you can read down the line, the more you will reach the 20/20 vision range.

Essential optical factors such as peripheral vision, hand and eye coordination, depth perception, focus, and color vision will affect your visual acuity score.

According to Tim Johnson, some children lose their normal vision when they reach the age of 8 or 9.

Their vision will stay the same for a long time until they reach the age of 60 years old.

Vision decline usually happens when people reach the age of 60 or 70.

Of course, other factors also affect loss of vision, such as:

  • Overstraining the eye
  • Eye disease
  • Accidents

Visual impairments come in a variety of shapes and levels.

Visual Acuity is not a reliable indicator of a person’s vision issues.


What Are Some Common Eye Conditions?


Also known as myopia.

When an object is close enough, you can see it clearly, but an object far away will appear blurred.

Nearsightedness affects approximately 30% of the population.

Experts can treat this condition with contacts or glasses.


The opposite of nearsightedness is also known as hyperopia.

Objects close to you are blurry, while those far away are visible.

Similar to myopia, this condition is also easily treatable.


A condition in which your cornea or lens has a shape imperfection.

If you have astigmatism, your eyes focus on two different locations rather than one.

Eye strain, discomfort, headaches, blurred or distorted vision, issues with night vision, and other effects may result from this.

For treatment, doctors may recommend contacts or glasses.


Your eye’s lens changes and becomes less flexible when this condition is present, making it challenging to focus on close objects.

This eye condition can happen at any age, up until about 40, but after 60, they get worse.

Macular Degeneration

Also known as Age-related Macular Degeneration(AMD).

A deterioration of the macula, also known as the central portion of your retina.

It’s a progressive disease which means it gets worse over time.

There are two types of AMD; dry macular degeneration and wet macular degeneration.

Treatment depends on the type of AMD you have.


Your eyes’ lens becoming cloudy could happen in either one or both eyes.

The lens behind the iris, the colored portion of your eye, can become blurry.

A double vision with objects is another possibility.

In most cases, old age or trauma is the cause of this condition.

Genetics, previous eye conditions, surgeries, chronic illnesses, and medications can also cause.


Glaucoma is a condition that harms the eye’s optic nerve.

From the retina to the brain, the optic nerve transmits images.

It usually has no symptoms at all and is not painful.

Your peripheral vision will, however, continue to deteriorate over time.

Regular eye exams allow us to identify glaucoma early on and significantly slow its progression.

When Should I Visit an Eye Doctor?

If you are worried about your eyesight, you should see an eye doctor as soon as possible.

Getting routine eye exams is important because your prescription may change.

Adults with vision issues between 19 and 40 should have an eye exam at least every two years.

Every year, adults over forty should have them checked.

Get your eyes checked every five years as an adult.

If you don’t have any vision issues up until 30, have a checkup at least every two to four years from 40 to 65.

You must have routine eye exams at least every two years after age 65.

If you notice any changes in your vision and feel you need to see your doctor more frequently, let them know.

Your doctor will screen for eye conditions like glaucoma during checkups because these conditions are treatable if identified early.
