The tumbling E chart tests the visual acuity of young children and others who can't read letters aloud. That means you can read at 20 feet a letter that people with "normal" vision can read at feet.
In some cases a standard Snellen eye chart cannot be used. One example is when the person having the eye test is a young child who doesn't know the alphabet or is too shy to read letters aloud.
Other examples include when the person is illiterate or has a handicap that makes it impossible for him to cognitively recognize letters or read them aloud.
In these situations, a modification of the Snellen eye chart called a "tumbling E" chart may be used. The tumbling E chart has the same scale as a standard Snellen eye chart, but all characters on the chart are a capital letter "E," in different spatial orientations rotated in increments of 90 degrees.
The eye doctor asks the person being tested to use either hand with their fingers extended to show which direction the "fingers" of the E are pointing: right, left, up or down.
Studies have shown that visual acuity measurements using a tumbling E chart are virtually the same as those obtained from testing with a standard Snellen eye chart.

The Jaeger chart consists of short blocks of text in various type sizes. A Jaeger eye chart contains several blocks of successively smaller text, generally ranging in size from J10 large print to J1 very small print.
The original Jaeger eye chart was developed in and contained seven paragraphs, each printed in a successively smaller font size.
The smallest paragraph you could read when holding the chart approximately 14 inches away determined your near visual acuity. Since then, there have been several modifications of the Jaeger chart or "Jaeger card" by different manufacturers.
Unfortunately, modern Jaeger charts are not standardized, and the actual letter sizes on different Jaeger cards might vary slightly.
The type scale on a modern Jaeger eye chart usually ranges from J10 approximately point type for Times New Roman font to J1 approximately 3-point type, Times New Roman.
A Jaeger eye chart may be used in two different ways, depending on what your eye doctor is trying to measure:. The chart is held at a specified reading distance such as 14 inches and you are asked to read the passage with the smallest type you can see.

And they help the Department of Motor Vehicles to determine if you are required to use eyewear for driving, or if you shouldn't drive at all because you are legally blind.
