Some customers said that normal marked cards are not safe enough in their countries, because many people are familiar with marked playing cards and know how to detect it. What is more, some poker clubs just prepare IR/UV contact lenses or for customers to check if there is marked cards available. To solve this situation, and now we developed a new kind of poker contact lenses to see unique invisible ink marked cards. The marks can not be detected by any UV or IR contact lenses, UV lights or any detected equipments.
According to Spectral theory, Visible light spectrum is from 0 .39~0.76μm. Different waves will make people sense different color due to the different electromagnetic. Under wave from770-622nm people can see red light, 622-597nm, orange; 597-577nm, yellow; 577-492nm, green; 499-455nm, Indigo color; 455-390nm, purple.
With these special poker cheating contact lenses, you can see the unique marks under any lights. Even some poker players with UV or IR contact lenses, they can see nothing on the back of the cards.
According to the theory that IR and UV light that can be sensed much easier than other wave visible lights. The marks for special contact lenses are not as strong as IR or UV marks which can be seen after you wear the contact lenses.
The quality is gorgeous for its high technology applied and complicated marking process,
