UV Contact Lenses to See through Playing cards

Lots of people, including me had searched poker strategies like “how to win at poker”, but all the tips you get is not as useful as the UV contact lenses. With them you could see through the playing cards, calculating the winning odds by knowing the value and suits of each card.

Why could see through the playing cards with the UV contact lenses?

In fact, it’s not wearing the UV contacts to see through the cards. It’s seeing the invisible ink markings hidden on the cards’ back with the help of the UV contacts. The types of invisible ink we used to mark on the playing cards can only be invisible when applied to the surfaces of playing cards, both of the plastic cards and paper cards. Once it dry, the written surface looks as if it were blank, with a similar texture and reflectivity as the surrounding surface. The ink will be revealed by application of an appropriate chemical, UV contact lenses are one of the application.

What the differences between UV contact lenses ans the normal contacts?

The most important different point is their purpose. UV contact lenses are used to see marked cards. The use of contact lenses is to help to correct refractive errors, like the eyeglasses. Then, their preservation methods are also different. UV contact lenses are keep in the pure water while normal contacts keep in the care solution. Last but not least, they look different. The middle part of the UV contact lenses are in purple, while the normal one is transparent. But both of them will not change the color of users’ eyes after wearing them. No one will find that you are wearing them.
