Contact lenses for cheating playing cards are a popular way to win at gambling games. They are a special type of contact lenses that can see invisible ink marks on the backs of poker cards. They can be used in many different casino games, including Texas hold’em and Omaha. These lenses are made using high-perspective technology, and are suitable to wear on any eye color. These lenses are very thin, and they are comfortable to wear.
Contrary to regular contact lenses, cheating cards contacts look exactly like prescription lenses. They have a purple filter in the center that can help you see the invisible ink markings on the cards. They can also read IR and UV ink marks. However, it is important to remember that they cannot be used for reading barcodes or other symbols on the cards.
To use the cheating lens, first wash and rinse it thoroughly. Put them in your eyes, and blink several time to make sure they are positioned properly. Wear them for no more than 8 hours a day. You can gradually increase your daily wear time. You can also read invisible ink marks written on a page of paper. But they shouldn’t be worn more than two hours at a stretch.
If you’re unsure how to use the cheating lenses, it’s best to ask for professional help. They will be able to help you find the right type of lenses for your specific needs and provide training on how to use them.
