Security Infared Contact Lenses
The lenses that are specialized in reading the marks of the playing cards are the infrared contact lenses. You can not see the marks neither with a normal eye, nor with other contact lenses. In this way they are the best cheating tool for games such as Texas Holdem.
Produced thanks to the newest technology, these are the lenses with which you will be able to see the invisible ink on the back of the cards. The UV lenses, for example, would not give you the possibility to see the marks, as the technology used for the UV and the IR contact lenses is different.
The most important thing is that the correspondence to the wink of infrared contact lens will not change the original color of the eye, so everything is natural. Also, these lenses would not harm your eyes, even after hours. The light you are under does not matter as well – yellow, white or red, the clarity of the marks will be the same.
