The first study for four languages was funded by the European Commission in the AMD-Read Project (QLK6-CT-2002-00214). One more language was supported by the German Academic Exchange Office. The production of the first edition of six languages was supported by Carl Zeiss Vision. The development of 11 more languages was supported by Alcon.

3. Features of the texts

IReST uses standardized paragraphs of text for measuring reading speed. The aim is to measure reading speed under natural conditions, i.e. reading newspaper print, which is a requirement of everyday life. Therefore, the texts are provided in a size (1M) and configuration which is very similar to newspaper print. The data given are for young normally sighted subjects (18-35 yrs) for reading aloud. Each language contains 10 paragraphs of text of equal length, difficulty and linguistic complexity. The texts are provided in 17 languages (Arabic, Chinese, English, Finnish, French, German, Hebrew, Italian, Japanese, Dutch, Polish, Portuguese/Brazilian, Swedish, Slovenian, Spanish, Russian, and Turkish). The texts are homogeneous and comparable within one language for repeated measurements and also between languages, which is especially suited for international studies.

4. Areas of application of IReST

For clinical and scientific use, when quantitative assessment of reading speed is required:

  • Low Vision patients
  • Disease monitoring in AMD, especially in treatment studies
  • After refractive surgery
  • After multifocal intraocular lenses
  • Neurological reading disorders
  • Developmental dyslexia
  • Studies with normal subjects
