What type of chart is often used to evaluate near vision?

1. LogMAR chart

2. Snellen chart

3. Jaeger chart

4. Monoyer chart

The correct answer is: Jaeger chart

The Jaeger chart is specifically designed for evaluating near vision. It consists of a series of paragraphs or phrases printed in varying sizes, allowing practitioners to assess a person's ability to read text at a close distance. This is particularly useful when determining the clarity of vision for reading and other close-up tasks. Unlike the LogMAR and Snellen charts, which are primarily used for assessing distance vision, the Jaeger chart focuses on near vision acuity. The Monoyer chart serves a similar function as the Jaeger chart but is less commonly used. The primary distinction is that Jaeger sizes are typically designated by the letter "J" followed by a numeral, indicating the size of the text, while the Monoyer chart may include different types of symbols or letters but still targets near vision assessment. Therefore, recognizing the purpose and structure of the Jaeger chart is crucial for understanding how near vision is effectively evaluated in a clinical context.
