Infrared Devices

Whether you are looking for Infrared contacts, infrared sunglasses, or infrared lens that connect to cameras we have it all! Check out our products below and let us know if you have any questions at info@howtomarkcards.com 


Infrared Contact lens

Our standard size lens comes with a built in infrared filter size 7 mm. The average size of a human pupil in midlight range is 6-8 mm. So basically in the normal poker setting, these infrared contacts will be the same size as your pupil and will be extremely discreet no matter what eye color you have! 

We offer our infrared contacts by themselves or bundled with cards. See our product below:

Infrared Sunglasses

We offer two types of infrared sunglasses. We offer the black plastic frame/dark lens and the Aviator Metal frame/blue lens. Both sunglasses (and contacts) have the same infrared vision. Check out our infrared sunglasses section below for bundle deals!

InfraBlue Technology

Offering the best of the best. The Infrablue is still very new and limited. We have Infrablue 12 mm contact lenses, black frame sunglasses, and a deck of cards to offer so far!

Infrared Sunglasses - Make your own

This reader kit allows you to create your own infrared sunglasses. They are a red filter sticky film that gets placed on any sunglasses, but please note they are not as advanced as the ones we sell.

Infrared Poker Analyzer / Camera's

We offer a very high tech device called the Poker Analyzer. This analyzer is a phone looking device with a hidden infrared camera on the side of the device. Hidden in the side, the infrared camera will scan the sides of marked cards and give the user the winning seat number! There are also infrared camera's that link up to the device for even more discreteness. See our products below.
