Power of Lens using Distance Rule Calculator

Formula

The formula to calculate Power of Lens is:

\[ P = P_1 + P_2 - w \cdot P_1 \cdot P_2 \]

Where:

\(P\) is the Power of Lens
\(P_1\) is the Power of First Lens
\(P_2\) is the Power of Second Lens
\(w\) is the Width of Lens (m)

Definition

Power of Lens is the degree of convergence or divergence of light rays as they pass through a lens, measured in diopters, and is a critical parameter in optics and ophthalmology.

Example Calculation

Let's assume the following values:

Power of First Lens (\(P_1\)) = 0.15
Power of Second Lens (\(P_2\)) = 0.32
Width of Lens (\(w\)) = 0.45 m

Using the formula:

\[ P = 0.15 + 0.32 - 0.45 \cdot 0.15 \cdot 0.32 \]

Evaluating:

\[ P = 0.4484 \]

The Power of Lens is 0.4484.
