These Xray Glasses can see through some type of materials making it possible to see through clothes that in the same condition cannot be seen by the naked eye. The theory behind it is simple.

Using the hi-tech glasses with a camera, railway police personnel at Zhengzhou east railway station in Henan province are matching the identities of passengers with information available on a police database to zero in on criminals, multiple reports said this week. Since Zhengzhou railway police started using the eyewear earlier this year, they have identified seven people suspected of crimes ranging from human trafficking to hit-and-run accidents," said a report in the People's Daily online that was cited by other media outlets. The police personnel also detected 26 cases of identity fraud, the reports said. The new technology requires one facial image for a similarity comparison in the database, he said. In the past, multiple facial pictures from different angles were necessary to achieve the same result.
