A method for measuring reading ability in which the test subject reads passages at a predetermined distance from the eyes of the test subject, the text size of the passages varying in steps in the reading order, the measurer assessing the test subject's reading ability on the basis of what the measurer hears. Each text passage contains at least one numeral word, indicating the visual acuity required by the passage. An auxiliary device for positioning the test subject's eyes at a desired distance from the object being viewed includes a plurality of parts of different lengths, linkable to one another in succession, from which parts the length corresponding to each desired distance is obtained by selecting and, when necessary, by linking the parts together. |
