Free Kids Visual Acuity Test
In an effort to help build a clear future for today's youth, Peepers Eyecare is offering a free visual acuity test for kids ages 14 and under.
What is a Visual Acuity Test?
The visual acuity test is used to determine the smallest letters you can read on a standardized chart (Snellen chart) or a card held 20 feet (6 meters) away. Special charts are used when testing at distances shorter than 20 feet (6 meters). Some Snellen charts are actually video monitors showing letters or images.
How the Test is Performed?
This test may be done in a health care provider's office, a school, workplace, or elsewhere.
You will be asked to remove your glasses or contact lenses and stand or sit 20 feet (6 meters) from the eye chart. You will keep both eyes open.
You will be asked to cover one eye with the palm of your hand, a piece of paper, or a small paddle while you read out loud the smallest line of letters you can see on the chart. Numbers, lines, or pictures are used for people who cannot read, especially children.
If you are not sure of the letter, you may guess. This test is done on each eye, one at a time. If needed, it is repeated while you wear your glasses or contacts. You may also be asked to read letters or numbers from a card held 14 inches (36 centimeters) from your face. This will test your near vision.
Why the Test is Performed?
The visual acuity test is a routine part of an eye examination or general physical examination, particularly if there is a change in vision or a problem with vision.
In children, the test is performed to screen for vision problems. Vision problems in young children can often be corrected or improved. Undetected or untreated problems may lead to permanent vision damage.
There are other ways to check vision in very young children, or in people who do not know their letters or numbers.
Visual acuity is expressed as a fraction:
• The top number refers to the distance you stand from the chart. This is usually 20 feet (6 meters).
• The bottom number indicates the distance at which a person with normal eyesight could read the same line you correctly read.
For example, 20/20 is considered normal. 20/40 indicates that the line you correctly read at 20 feet (6 meters) away can be read by a person with normal vision from 40 feet (12 meters) away.
Even if you miss one or two letters on the smallest line you can read, you are still considered to have vision equal to that line.
What Abnormal Results Mean
Abnormal results may be a sign that you need glasses or contacts. Or it may mean that you have an eye condition that needs further evaluation by a provider.
