Invisible ink that can be seen with special glasses is typically created using materials that are visible in the infrared (IR) spectrum. Regular ink or markings made with such ink are invisible to the naked eye but can be detected with the help of infrared light.
These special glasses, often referred to as “infrared glasses” or “infrared contact lenses,” contain filters that block visible light and allow only infrared light to pass through. When you wear these glasses and look at objects or surfaces with invisible ink markings, the markings become visible as they reflect or emit infrared light.
Infrared ink is sometimes used for security purposes, such as marking valuable items, creating covert markings on documents, or for anti-counterfeiting measures. However, it’s important to note that using infrared ink or special glasses to cheat at card games or any other activities is unethical and illegal.
As mentioned before, cheating in any form is not only against the rules of most establishments but also against the principles of fair play and integrity. Engaging in cheating can lead to severe consequences, including being banned from the venue or facing legal action. It’s always best to play games honestly and rely on skill and strategy for a fair and enjoyable experience.
