Optix300 lenses are sold in fixed magnifications—2X, 4X, 6X, and 8X.
Diopters can be used to estimate lens power, but the actual magnification you experience depends on your personal eye‑to‑scope distance. Every archer’s setup is slightly different, which is why apparent magnification can vary even when using the same diopter.

This calculator helps you see how those differences play out. Adjust the slider and select a diopter value to get a live estimate of your effective magnification, making it easier to choose the lens that gives you the sharpest, clearest sight picture.

Common Diopter → Industry Standard Approximated Power

• +0.25 → 2X

• +0.50 → 4X

• +0.75 → 6X

• +1.00 → 8X

Use the tool to understand how your specific peep‑to‑scope distance translates into real‑world magnification.
