Marked cards are contact lenses that enable people to see luminous marks on playing cards. These lenses can be used for magic cards and other games in which the back numbers or suits are visible to the wearer. The marked contact lenses are more private than other cheating tools. You can wear them during the game without anyone knowing. They provide a good visual experience and will not change your eye color.
There are different types of contact lenses on the market. Some are soft and others are hard. Choosing the correct one depends on what you prefer and the game that you want. Soft contacts work best for beginners because they are more comfortable, easier to clean, and have a better fit. However, hard contacts are better for those who have a problem with dry eyes, as they are more durable and don’t move around easily.
When choosing the type of contact lens for playing cards, you should choose one that matches your eye color. For example, if you have blue or green eyes, the best choice would be to get a contact lens with a yellowish hue. This will help your eyes look brighter and will not affect the color of the cards.
Clarity is also a factor to consider, when purchasing contact lenses that will be used with marked cards. The color of your contact lenses can affect how clearly you are able to read the marks on cards. The higher the quality of your contact lenses, the clearer you can read the marks.
To ensure comfort, you should also check that the lens has a very low moisture content. You can test this by placing the contact lens into pure water and watching how it reacts. If the contact lens is left with a lot liquid, it can cause irritation. The contact lenses should have a high oxygen permeability as well, as this will improve your wearing comfort.
The most popular contact lenses to mark cards are IR lenses. These lenses work by reflecting the infrared beam onto the backs. This allows you see the invisible luminous mark on the back of the cards. They are a useful tool for cheating at poker and magic. The IR contact lens is also a great way to read barcode marked cards. While these are more expensive than traditional contact lenses, they are worth the investment because they will help you win more games. They are also more convenient than other cheating products such as laser marked cards.
