Enter the gap size (arc min) into the Visual Acuity Calculator. The calculator will evaluate the Visual Acuity.
- Numerical Aperture Calculator
- Line of Sight Calculator
- Reading Accuracy Rate Calculator
- Visual Angle Calculator
Visual Acuity Formula
The following two example problems outline the steps and information needed to calculate the Visual Acuity.
VA = 1 / GS
Variables:
- VA is the Visual Acuity ( )
- GS is the gap size (arc min)
To calculate the visual acuity, divide 1 by the gap size.
How to Calculate Visual Acuity?
The following steps outline how to calculate the Visual Acuity.
- First, determine the gap size (arc min).
- Next, gather the formula from above = VA = 1 / GS.
- Finally, calculate the Visual Acuity.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
gap size (arc min) = 3
VA = 1 / GS = ?
