Law enforcement called the bluff of two separate poker players who allegedly used infrared contact lenses to cheat casinos.

According to news reports, Italian national Stefano Ampollini and New Jersey native Bruce Koloshi used invisible ink, marked cards and infrared lenses to tilt the odds in their favor. Police in the US and Europe said it’s the first time they’ve heard of cheaters using infrared lenses to bilk casinos.

A French court sentenced Ampollini to two years in jail. Koloshi was arraigned in Connecticut last month.

Ampollini, who said he ordered his lenses from China, won more than $120,000 from a casino in Cannes before being caught. He piqued the interest of casino security after winning more than $95,000 and folding two good hands. He admitted that his special contact lenses “were designed to see things that you normally wouldn’t be able to see.”
