The Readability of Sample Stories for Eye Movement Recording

For more than 40 years, the profession of optometry has relied upon an established series of graded reading passages and norms to evaluate the mechanics of reading. Educational Developmental Laboratories (EDL) initially copyrighted these stories in 1958.1 The passages tested students from first grade to adult levels. These same stories have continued as the gold standard with a number of different eye movement recording devices including the Reading Eye Camera I and II, EyeTrac I and II, the Applied Science Labs Model 110 and 220, and all versions of the Visagraph.
