the IReST differs from prior text charts that used single sentences by employing linguistically standardized paragraphs. They close a gap in the diagnostics of reading performance. The paragraphs are designed to resemble everyday life situations of reading continuous text, such as in books or newspapers.

• Reproducibility
• Comparability
• Success documentation
• Available in 19 languages and dialects

• Easy to use
• Easy to handle
• Easy to measure (by stopwatch)
• Easy to calculate(normal values and formula included)
• Highly calibrated for reproducible results across all languages

Characteristics:  

• Set of 10 paragraphs of text in each language for repeated measurements
• Comparability between languages for international studies
• Natural conditions: newspaper print, meeting the demands of everyday life

Applications:

• For normal subjects
• For patients with low vision (monitoring of disease, effect of treatment and rehabilitation)
• For patients with developmental dyslexia (severity of the reading disorder, the effect of training, etc.) - for juveniles and adults
• 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

User groups:

• Ophthalmologists and neurologists
• Optometrists and ophthalmic opticians
• Orthoptists and low vision specialists
• Teachers and psychologists
• All reading researchers

The level of difficulty corresponds to sixth-grade reading (10–12 years), which is comprehensible for teenagers and adults. Due to lower variance, measuring the reading time of a complete paragraph rather than a single sentence or random words is more reliable. Furthermore, it can provide some information about fluency, fatigue, and mistakes.
