Invisible ink lenses is a special contact lens that can be processed to make the invisible marks of poker cards visible. They can be used to cheat at poker games, magic shows or other card tricks. Based on optical principles, they can detect the infrared band of a marked playing card.
All the invisible ink lenses on our website are made with safe materials. They don’t change your eyes’ color and can be worn for a long time without discomfort. You can choose from a variety of colors to match your eye color. Red infrared lenses are suitable for people with a red pupil, and brown ones are appropriate for people with a brown pupil. All of them are easy-to-use and safe for your eyes.
There are two major types of luminous-ink poker cards detectors, invisible ink lenses and luminous-ink glasses. Both are used to see the invisible marks on both plastic and paper playing cards, but the UV invisible ink contact lenses have more advantages than luminous ink glasses. They can be worn along with a poker scanner, making them more convenient for daily use.
When choosing a UV invisible ink lens, you should choose a light color. Darker IR lens can cause discomfort if worn for a long period of time. The dark colored luminous lenses might not match your eye color.
