GOGGLES-TRAINERS Russian patent published in 2006 - IPC G02C7/10 A61F9/02 

FIELD: optical instrument engineering.

SUBSTANCE: goggles-trainers can be used for production of vision devices, for example, of goggles for improving and correcting vision. Goggles-trainer has frame and lenses made for formation of transparent holes onto non-transparent background. Lenses are made in form liquid crystal screens connected to microchip. Versions of selected non-transparent arrays are put into memory of microchip. Any array has transparent holes of specific size. To control size of transparent holes, illumination detector and range finder are introduced into goggles. Range finder and illumination detector are connected with microchip. To change spectral characteristics of liquid crystal screens depending on illumination, light spectral composition detector is introduced into goggles which detector is connected with microchip. Besides, microchip is connected with power supply and control buttons. Lenses are coated with toned film having specific spectral characteristics.

EFFECT: improved efficiency of training.
