The 9mm contact lenses are most suitable for people with dark eyes. As these lenses can make the colour of your eyes slightly darker, we reccomend them to the dark-eyed customers. The greatest advantage of these lenses is that they offer the clearest visualization of the card markings.
When you wear the 9mm contact lenses, you will be able to see the marks on the back of the cards. With a naked eye you shouldn’t be able to see the marks.
These lenses are also called the marked cards contact lenses as they are the best for games such as Texas Hold'em and Baccarat. It will be no difficult for you to know the five community cards as you can see the marks of all the playing cards clearly just with the help of the 9mm contact lenses.
