If they're aixiz lenses in the standard M9x.5 housings, the glass lenses will be longer and the housings will be made of a blackened brass. The aryclic lenses will be shorter, single element, and the housings are black plastic.
The aixiz acrylics I have also have no noticeable AR coating. The reflections off the glass lenses should have a noticeable tint. 405/445 will have a yellowish tint and 650 lenses will have a blue tint.
