You can use them to see marked cards clearly. They are commonly used in poker games and magic. They are made with the same material that regular contact lenses so they won’t cause any harm to your eyes. But they must be taken care of properly. You’ll have to clean them with a lens cleaner regularly, and you should only wear them for about an hour.
The purple tint of these luminous ink lenses allows them to see the marks on marked card. The purple part of these lenses will help them to receive the IR reflected from the invisible ink of the marked cards. This enables the cards to be seen, even though they look normal and clean from the outside.
A man was arrested after he was accused of using luminous contact lenses to cheat in a casino. The 54-yearold man from Summit in New Jersey reportedly marked cards using the luminous marker at the Mohegan Sun Casino Sunday. He is accused of conspiracy to commit larceny and criminal impersonation.
The package includes 2 sets of our luminous ink contact lenses, glass protective bottles, a contact lens case, contact grip tweezers, discrete storage cases and a deck of professionally printed Bee or Bicycle brand marked cards. The lenses come with a contact lens that is 7 mm in diameter (a little larger than the size your pupil), so they can be worn for any eye colour.
