Fractions are shown to the left of each row and identify how well you can see. If you could read clearly to the fifth line, for example, your vision will be expressed as having 20/40 vision; if you could read clearly to the seventh line, your vision will be expressed as 20/25.

Eye charts can be configured in various ways. Generally, if you can read the big "E" at the top of the chart, but none of the letters lower than that, your vision is considered 20/200. 20/200 vision means that you can read a letter at 20 feet that people with "normal" vision could read at 200 feet.

Each line below gets incrementally smaller until the letters are so small that the only people who have better than 20/20 vision can read them. The size of the letters is precisely calculated to represent perfect adherence to the visual standard of the 20/20 scale. Even the types of letters used are carefully chosen.

Ensure proper room lighting and set phone brightness to 100%. Hold the screen 4 feet (1.2 m) from the patient (approximately the end of a standard hospital bed if patient is sitting upright). Test each eye independently. The patient should completely cover the opposite eye.
