Distance Visual Acuity Conversion: From Feet to Meters

What is the equivalent distance in meters for a Distance Visual Acuity (DVA) of 20/20 feet?

(A) 6.10 meters (B) 9.14 meters (C) 12.19 meters (D) 18.28 meters

Final answer:

The equivalent distance in meters for a Distance Visual Acuity (DVA) of 20/20 feet is 6.10 meters.

Understanding Distance Visual Acuity is essential in evaluating one's vision. In this case, the question asked for the metric conversion of a DVA of 20/20 feet. A DVA of 20/20 is considered normal vision, indicating the ability to see objects clearly from a distance of 20 feet.

The equivalent distance in meters for a DVA of 20/20 feet is calculated by converting feet to meters. Since 1 foot is approximately 0.3048 meters, we can determine the equivalent distance by multiplying 20 feet by 0.3048. This calculation yields approximately 6.10 meters.

It's important to note that normal vision, represented by a DVA of 20/20 feet, is crucial for daily activities and tasks that require clear vision at a distance. Understanding these measurements helps healthcare professionals assess vision and provide appropriate care.
