Marked cards have been around for centuries and are used by magicians and poker players to cheat in games. The markings on these cards allow the player to see the values and suits of the cards. They can also be used by mentalists and other entertainers to perform mind reading tricks.
There are several ways to read marked cards, including a poker analyzer, a scanning camera, or contact lenses. Using the right tool is crucial to successfully detecting the markings on these cards.
The most popular method to read the markings on these cards is through the use of contact lenses. These are a simple and effective method to detect the invisible luminous ink markings on these cards.
These contact lenses are usually IR or UV type. They convert your normal vision into a purplish vision that allows you to see the luminous ink markings on the back of the cards.
Some of these contact lenses are made with a special material that makes them more resistant to damage than other contact lenses. They also have a longer lifespan than other types of contact lenses.
They are also easy to clean and can be disinfected with a solution that has a pH level of 8-9. They are not intended to be worn continuously or overnight, so they should be removed and stored in a clean contact lens case before each use.
You should also keep your fingernails short and clear them before putting them on each time, so as not to scratch the surface of the lenses. It is also important to avoid rubbing your eyes with the lenses, as this can cause corneal damage.
The lenses are available in various sizes and colors to suit your needs. They come in both soft and hard materials. The hard contact lenses are easier to maintain and provide a brighter surroundings. If you are not sure whether you will be comfortable wearing these lenses, ask an eye care professional to test them.
If you are a beginner and have never worn contact lenses before, it is a good idea to buy the lenses in the small size so that you can get used to wearing them before you decide to invest in a larger size. The smaller size contact lenses will work better with the blue and green eyes, while the larger ones will be more suitable for dark brown eyes.
Some of the lenses are designed to correct your vision, so you should choose the ones that match your current prescription. Some of these contact lenses are also made with a special material that is more resistant to moisture than other contact lenses.
Buying these lenses is not as expensive as you might think. They are normally sold for about 200usd, which is a good price for their quality and effectiveness.
If you are looking to read the marked cards at a low cost, these contact lenses might be a good choice for you. They are cheaper than other options and are easy to use. They are perfect for beginners and are a great way to see the marked cards without compromising your vision.
