Summary
Conventional reading charts are widely used but often lack validation. Validated digital reading tests are emerging as the future standard for reliable visual capacity assessment.
Area of Science:
- Ophthalmology
- Optometry
- Human Visual Performance
Background:
- Near and intermediate visual acuity are crucial for daily tasks, amplified by digital device use.
- Conventional reading charts, like Jaeger charts, dominate clinical practice but frequently lack validation.
- International Council of Ophthalmology (ICO) recommendations guide reliable reading capacity assessment.
Purpose of the Study:
- To systematically review and analyze conventional and digital reading tests.
- To explore the integrated characteristics and validation status of various reading assessment tools.
- To identify trends and future directions in visual acuity testing.
Main Methods:
- Systematic literature review conducted across PubMed, Google Scholar, and Springer databases.
- Search timeframe: February to March 2021.
- Inclusion of data from 11 descriptive and 24 comparative studies on reading charts.
Main Results:
- Conventional printed reading charts remain prevalent in clinical settings, yet many, including Jaeger charts, are not validated.
- Only reading tests adhering to ICO recommendations provide reliable reading capacity assessment.
- Digital reading tests are increasing in use, with options ranging from installable applications to web-based platforms.
- Validated digital tests are poised to become the future standard in clinical and research environments.
Conclusions:
- Validated digital reading tests are expected to supersede conventional methods due to their reliability and accessibility.
- Ophthalmologists should carefully select digital tests that align with their specific examination protocols.
- The evolution towards validated digital tools promises more accurate and standardized visual capacity assessments.

The Wald-Wolfowitz test, also known as the runs test, is a nonparametric statistical test used to assess the randomness of a sequence of two different types of elements (e.g., positive/negative values, successes/failures). It examines whether the order of the elements in a sequence is random or if there is a pattern or trend present. This nonparametric test applies to any ordered data despite the population and sample data distribution, even if a higher sample size is available.

Multiple comparison test, abbreviated as MCT, is a post hoc analysis generally performed after comparing multiple samples with one or more tests. An MCT will help identify a significantly different sample among multiple samples or a factor among multiple factors.
It would be easy to compare two samples using a significance alpha level of 0.05. In other words, there is only one sample pair to be compared. However, it would be difficult to identify a significantly different sample if the number...
