IR Contact Lenses for Marked Cards – A Long-Standing Choice for Discreet Reading
Infrared contact lenses designed for back-side marked cards have been a reliable tool among seasoned players and magicians for years. To accommodate different preferences, we offer them in four diameter sizes: 4mm, 6mm, 7mm, and 9mm. These lenses are known for their ability to make invisible ink markings on the backs of cards stand out with sharp clarity.
How to Pick the Right Pair for Your Needs
These lenses are non-prescription and serve a single purpose: the infrared coating that enables you to read marked card backs. For those who need vision correction, the practical workaround is to wear the IR lenses underneath your regular prescription glasses—ensuring clear sight while keeping the cheating function fully intact.
Standard Design and Custom Fit Options
By default, our lenses come with a clear base and a central dark purple filter—the area responsible for detecting infrared ink. This filter typically measures 7mm or 9mm in diameter, striking a good balance between readability and comfort. If you need a smaller or more discreet filter, we can adjust it to your specifications.
