Visual Angle Calculator. The visual angle of an object is a measure of the size of the object's image on the retina. The visual angle depends on the distance between the object and the observer -- larger distances lead to smaller visual angles.
3 paź 2024 · The visual angle (\(VA\)) is calculated using the formula: \[ VA = \tan^{-1}\left(\frac{S}{D}\right) \] where: \(VA\) is the Visual Angle in degrees, \(S\) is the visual size, and \(D\) is the distance from the observer to the object. Example Calculation
