- Near PD Calculator (Pupillary Distance) gives you a fast estimate using your inputs and updates instantly when you change any value.
- Formula: Near PD ≈ Distance PD − 3 mm; Monocular PD = Distance PD ÷ 2
- Input definitions: • Distance PD: the numeric distance pd used in the calculation
- Enter values using the units shown next to each input field (e.g. kg, cm, years).
- This calculator uses widely accepted health formulas and returns screening estimates only. It does not replace a diagnosis from a qualified healthcare professional.
- Compare your result with published reference ranges. Values outside the normal range warrant a conversation with your doctor.
- Practical tip: test a low, medium, and high scenario to understand sensitivity before making decisions.
Example Calculation
Inputs
- Distance PD: 63 mm
Suppose you enter: Distance PD = 63. The calculator applies the formula (Near PD ≈ Distance PD − 3 mm; Monocular PD = Distance PD ÷ 2) and shows all output values below. Change any input field to immediately see how the result changes.
