Main Digest
The Snellen eye chart was first designed by a Dutch ophthalmologist, Herman Snellen in 1860s. Other types of commonly used eye charts include the Landolt C, and the Lea test.
Below you will find several variations of printable Snellen eye charts you can download and print for home use to determine your visual acuity ie. 20/20 vision.
If a person cannot achieve a visual acuity of 20/200 (6/60) or above in the better eye, even with the best possible glasses, then that person is considered legally blind in the United States. A person with a visual field narrower than 20 degrees also meets the definition of legally blind.
Visual acuity (VA) is acuteness or clearness of vision - especially form vision, which is dependent on the sharpness of the retinal focus within the eye, the sensitivity of the nervous elements, and the interpretative faculty of the brain. VA is a quantitative measure of the ability to identify black symbols on a white background at a standardized distance as the size of the symbols is varied. The VA represents the smallest size that can be reliably identified. VA is the most common clinical measurement of visual function.
- A 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.
Someone with 20/20 visual acuity does not have 'perfect' vision, since it is quite possible to see better than 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; in this respect, their vision is much better than human eyesight. Many humans have one eye that has superior visual acuity over the other.

What Does the Capital Letter 'E' on Eye Charts Mean?
In many modern eye practices today, eye charts may be projected so that they are seen through a series of mirrors. They may also be in the form of wall-mounted or hanging charts. At the top of the chart there is typically a large letter 'E' Below that letter, there are rows of capital letters, with each row progressively smaller than the previous one. In some cases, there may be numbers or pictures in place of letters. Some charts may consist of the letter 'E' in decreasing sizes, pointing in different directions. This is called the 'tumbling'E' chart and is used for people who have difficulty speaking, but can point to indicate which direction the 'E' on a certain line on the chart is facing.
Referral to an ophthalmologist should be considered if a persons visual acuity is worse than 20/40, with glasses, if applicable, and visual impairment is interfering with their daily activities.
Printing the Charts:
- NOTE: Due to differences in monitor size and resolution, this test is not accurate when viewed on a computer.
- Be sure you select these options on your printer - Maintain aspect ratio, Use full page, Center image on page.
- To print out the eye chart below right click the chart you wish to use and save it to your desktop, you can then print it from there by right clicking and selecting print from the menu.
How to Use Eye Charts:
- The Snellen Eye Chart is read while standing 20 feet from the chart. Be sure the room you are in is well lit but is not in full sunlight.
- Test one eye at a time (cover the other eye with your hand or card etc.). The lowest line that you can read correctly is your visual acuity.
- At 20 feet (6 meters) you should try to read the letters on the row 6th from the top. If you can read that line ok it means you have visual acuity of 20/40 or better: 1/2 normal.
- Standing at 10 feet from the eye chart if the smallest letters you can read were on the 6th row from the top, this would give you an acuity of 10/40: 1/4 normal.
- If you are nearsighted, your vision will become clearer the closer you stand to the eye chart.

Benefits of Testing Your Vision at Home
Most people do not notice changes in their vision until it has significantly deteriorated. Doing a self-test at home may alert you to potential vision problems much sooner than if you had waited until you noticed yourself struggling to read road signs and menus.
How to Use the Eye Chart from our Eye Care Center
To use the eye chart from our eye care center, download the chart onto your desktop, laptop or tablet and print the chart. Tape the chart to a wall at your eye level.
Next, step back 10 feet and pick out the smallest line you can read. You can have a friend or family member point to certain lines and tell you if you read the letters correctly. Then, test your eyes individually by covering one eye, reading the chart then covering the other.
