Contact lenses for back-side marked cards are not a novelty in the market. Catering to diverse customer needs, these lenses come in various sizes: 4 mm, 6 mm, 9 mm, and 12 mm in diameter. Renowned for their magical ability, these lenses allow users to read invisible infrared ink markings on cards.
Wondering how to select the ideal marked cards contact lenses for yourself? Here’s some guidance to assist you in choosing the right infrared filter contacts that can reveal hidden marks on cards.
Typically, purchasing contact lenses involves visiting an optician to obtain a prescription. However, magic contact lenses do not serve the purpose of correcting vision defects. It’s important to understand that these are specialty lenses, treated with a coating process to function as a plain filter. For those with myopia, it is advised to wear these infrared contacts for their magic capabilities and use corrective glasses simultaneously to manage vision impairments.
In most cases, the color of these specialized contact lenses is transparent with a dark purple section in the middle. This dark purple segment is crucial as it enables the wearer to see the invisible ink marks on the reverse side of playing cards. This functional area typically measures 9mm or 7mm in diameter, but can be adjusted to meet specific requirements.
Additionally, these lenses come with different quality standards. Standard lenses are primarily used for reading infrared markings and are quite affordable, making them accessible to a wide audience. If you're new to this type of product, the standard version is an excellent starting point. On the other hand, professional-quality infrared filter contacts are designed to be more comfortable and suitable for extended wear, making them the preferred choice for professional poker players.
