If you have ever played poker, you know that luminous ink marked cards can be very difficult to see without the proper poker glasses. These glasses have red filters in the lens that can allow you to read the infrared luminous marks on invisible ink marked cards.

These glasses are disguised as sunglasses, which makes them look like any other pair of regular sunglasses that you would buy at the store. You simply wear them to play the game, and your opponent will never know that you are using these special glasses to cheat at the games.

This is a great tool for poker players who use luminous ink marked cards because it will help you see the back of the card clearly. It will also help you keep your eyes focused on the poker game instead of being distracted by other things around you.

Invisible ink, also known as security ink or sympathetic ink, is a substance used for writing that is invisible either on application or soon thereafter. It can later be made visible by some means, such as heat or ultraviolet light.

It can be applied to writing surfaces with a specialty purpose stylus, stamp, fountain pen, toothpick, calligraphy pen, cotton swab or even your finger. It can also be made visible by exposing it to heat, such as using a radiator, ironing or putting it in an oven, or by viewing it under UV or IR light.

There are several different kinds of invisible ink. Some of them are organic substances that oxidize when heated, turning them brown. Other types are chemically-based substances that rely on dilution to become visible.

Most of these invisible inks are made visible by one of these methods: heating the written material, contacting it with a substance that reacts with phenolphthalein, or viewing it under oblique light. In some cases, the inks can be reformulated to make them disappear again, such as by placing them inside an iodine fume cupboard.

Invisible ink can be used to write secret messages on any surface, but it is often used as a security precaution for sensitive documents and information. This is a good way to protect your privacy and prevent snoopers from reading your confidential documents.

Some people are concerned about their privacy when they are living in a joint living arrangement, such as a dorm room or apartment. In these situations, a simple pen that writes in invisible ink is a great tool to help maintain privacy and keep your private information from falling into the wrong hands.

If you are worried about your privacy, consider purchasing an invisible ink pen and a pair of VID8000 Glasses. The glasses are stylishly designed to resemble sunglasses and are specifically designed to see the spectrum of invisible ink that is displayed on paper and other materials.

The VID8000 Glasses are great for reading a variety of inks, such as luminous ink, invisible ink, and steganography ink. They are available in different sizes and colors, so you can choose the best one to match your style.
