The Smart_Mirror add-on software for Easy_Projector, Smart_Projector and Smart_Shape_Premium allows to check two items that are symmetrical to each other (for example, the right and left lenses of sunglasses) using one single measuring program.

Created the master program from one of the two items (for example, the right lens), then it is possible to use the Smart_Mirror feature to control both items, choosing the desired mode (right or left).
