Frequently Asked Questions

Q: How does a Fresnel magnifying card work?

A: A Fresnel lens uses a series of concentric ridges etched into a flat plastic surface to bend light and produce magnification — just like a conventional lens, but in an ultra-thin, lightweight card format. Simply hold the card a short distance above the text or object you want to inspect and look through it for a magnified view.

Q: Is this credit card magnifier durable enough for everyday wallet carry?

A: Yes. The lens is made from flexible PVC, which resists cracking under the light bending that occurs in a wallet. The CE-certified construction and sturdy ABS body ensure it holds up well to daily use. For best results, keep it in its OPP sleeve when not in use to avoid surface scratches.

Q: What is the actual magnification power of this loupe?

A: This Fresnel card loupe provides 3× magnification, enlarging text and fine details to three times their original size — ideal for reading small print, examining stamps or coins, or inspecting intricate details in crafts and collectibles.
