Which chart is noted for enabling up to 700-foot characters and can be walked up to the patient?

• A. Feinbloom Chart
• B. Snellen Chart
• C. ETDRS Chart
• D. Printed Charts

Answer: (D)

The key idea is flexibility in distance testing and mobility. Printed charts can be produced in a wide range of letter sizes, including extremely large ones that could be read from far away. Because they are portable, you can bring or walk the chart to the patient, even during a mobility-style assessment. This lets you evaluate distance vision in a real-world context and at distances that aren’t fixed by a wall chart. Fixed wall charts, like the Snellen and ETDRS setups, are designed for specific testing distances and standardized formats, which limits their use when you need to test very large letters or move the chart with the patient. The Feinbloom chart is a low-vision tool with oversized letters too, but it’s typically used in closer-range testing rather than being walked to the patient at long distances. So, printed charts are best for scenarios that require very large print and the ability to physically bring the chart to the patient, matching the description of up to 700-foot characters and walking the chart to them.
