Good vision is crucial for maintaining a high quality of life. From reading books to driving a car, our ability to see clearly plays a significant role in our daily activities. One way to measure the sharpness of our vision is by using an eye chart, also known as a vision chart.
Printable Vision Chart
One of the most commonly used eye charts is the Snellen chart. It was developed by Dutch ophthalmologist Herman Snellen in 1862 and has become the standard method for testing visual acuity worldwide. The Snellen chart consists of several rows of letters, with each row becoming progressively smaller. A person’s visual acuity is determined by the smallest row of letters they can read accurately.
What is 20/20 Vision?
When we hear the term “20/20 vision,” we often associate it with perfect eyesight. But what does it actually mean? The term refers to normal visual acuity, or the ability to see at a distance of 20 feet what a person with normal eyesight should be able to see at that distance.

Vision tests are not limited to distance vision alone. Near vision, which is the ability to see clearly at close distances, is equally important. Printable near vision eye charts are available for individuals to test their near vision without having to visit an optometrist. These charts are useful for those who frequently engage in activities such as reading or working on a computer at a close distance.
Snellen and Vision Chart
The Snellen chart not only helps measure visual acuity, but it is also used in testing color vision. The chart includes rows of colored dots that form specific patterns. By identifying and correctly naming the patterns, ophthalmologists can evaluate a person’s color vision. This is essential for various professions, such as pilots or graphic designers, where color recognition is crucial.

Visual acuity testing using the Snellen chart is straightforward. Individuals stand or sit at a designated distance (usually 20 feet) from the chart and cover one eye. They read the letters aloud, beginning from the top row and progressing downwards until they can no longer accurately identify the letters. This process is then repeated with the other eye. The results are recorded as a fraction, with the numerator representing the distance at which the person is standing and the denominator indicating the distance at which a person with normal vision should be able to read the corresponding line.
Snellen Near Vision Chart
Snellen near vision chart is specifically designed to assess near visual acuity. It is similar to the standard Snellen chart but is smaller in size. People use it to determine their near vision capabilities in situations where close-up vision is essential, such as reading fine print or working on intricate tasks.
