We will talk about using the contact lenses that will detect the luminous marked cards. Contact lenses have got small purplish filters that are built in the lens. If you put contact lenses in eyes your vision will be transformed in the purplish vision (like black light) and you can read the luminous “invisible” or infrared marked cards. Markings are applied on the back of the red and blue cards. Contact lenses can read both that is one benefit over glasses that will just read back of the red backed cards. Contact lenses are highly effective and the discreet way of reading invisible markings. Contact lenses are actually made from same material that regular lenses are made from. Size of the whole contact lens is around 13mm that is a standard size of the contact. There’re some different sizes for a filter.
