Invisible ink (also known as security ink) is a substance used for writing that is invisible either on application or soon thereafter but can later be made visible by some means. Invisible ink glasses are a favorite poker tool of many players. These luminous sunglasses can help players win poker games by identifying the marks on the backs of invisible ink marked playing cards.
In addition to helping to improve a person’s vision, wearing the right pair of glasses can also make them look good. Some people like to wear clear frames, as they are transparent and can give off a stylish appearance. It is important to select the right pair of glasses for each person’s face shape. A person with round features should wear square frames in order to balance the face and make it appear slimmer.
Glasses should fit the head comfortably and not press tightly against the ears. The temples should press firmly on the ears, but not so tightly that they are uncomfortable. If the frames are too tight, they can slide forward while the person is wearing them.
Invisible ink glasses can also be used to identify invisible luminous ink marks on cards, which only special infrared filter can see. These luminous ink sunglasses have red filters placed into their lenses to help people see these invisible markings. Moreover, these luminous ink sunglasses are also able to hide a player’s mood and prevent other players from reading information on their eyes during the game process.
