Infrared Contact Lenses

Infrared contact lenses here refers to the contact lenses with an infrared or ultraviolet light filter that can see through the IR or UV ink marked cards. Usually, the infrared contact lenses can see the infrared ink marked cards only, and here in our company, we integrate UV filter into it so that our marked cards contact lenses can see both the infrared marked decks and UV ink marked cards.

These kinds of invisible marked playing cards always look the same as the normal clean deck of cards and only the special infrared contact lenses can tell the invisible marks of suits and numbers while people with naked eyes can't see any markings nor signs at all.
