Chris Angel and David Blaine make reading cards appear simple. It almost seems like they can read right through the cards or have some type of power that is over human skills. It’s an illusion. They are not using any skills what-so-ever.They use magic trick with secret contact lenses on their eyes.
In truth, they are using an object that ANYONE can use or master in a matter of minutes. Wouldn’t it be nice if you could know every suit and every card in a deck of cards? Have you ever heard of luminous ink? Luminous ink is a type of invisible ink that can be coated on the back of a deck of cards and essentially is completely “invisible” to the naked eye. Even a person with bright eyesight will not be able to detect these markings.
However, with simple lenses the markings pop out at you and exclusively you. The lens is a reddish-purple color which allows you to see the imprinting that are normally not visible to the naked eye. The two principle ways people read the markings are luminous ink contact lenses and luminous ink glasses. This section will clarify the luminous ink contact lenses. There are 3 elements you must know for the contact lenses; eye care, eye colour, and contact lens care.
Luminous ink contact lenses are a special lens with a purple filter formulated into the clear lens. The lens itself, is the same size as a common contact lens. The filter that enables you to read the imprinting on cards range anywhere from four millimeters to nine millimeters. Keep in mind the entire contact lens itself is 13 millimeters. The people with lighter colored eyes (green and blue) will wish to go with the four millimeter filter size contact lenses while somebody with darker eyes can get away with wearing nine millimeters and seven millimeters filter size since the filter will blend in with the darker eyes.
When it comes to eye care, you must apply caution! Keep in mind that contact lenses should not be in the eye for more than eight hours. Only insert these lenses into your eyes when you perform card tricks. These should not be worn all the time especially since the filter modifies the color of your vision to a dark purple. If the contact feels scratchy take the contact out and employ with solution so that your eye is not “bugging” you. These contact lens readers are special, but your eyesight is most weighty!
Care for your contacts. When you begin putting the contacts in your eyes you must use contact solution and clean lightly around the contact before putting in your eye. This helps keep the build up of protein places from the last time you wore the contacts. When you bring the contacts out, you should put the contacts in a case at room temperature and store in solution. This will guarantee a long use life for your contacts.
Keep in mind that the three elements of wearing contact solutions for magic card tricks, you have to know which size filter suits your eye color, you must care for your eyes, and you have to care for the contact lenses.
