When the device is switched on, it automatically performs the imaging such that all images are useful. The device comprises a camera arrangement with optics and a camera sensor, and an illumination arrangement. The device comprises a control arrangement that switches the camera arrangement to take automatically one or more images of the eye, when the device is in front of the eye. The device comprises an image analyzing arrangement or a connection to an image analyzing arrangement that is provided for detecting a reflection in the image taken by the camera arrangement or in the image area of the camera arrangement and for transmitting the information about the detected reflection to the control arrangement which is provided thereby to repeat or decline imaging. When repeating the imaging the control arrangement alters the parameters of imaging.

Abstract: The invention relates to a lens exchanging structure. Lens-frame assembling parts of a glasses frame of a main spectacle frame are assembled with lens frames. Intercalating flanges on one sides of the lens frames are correspondingly intercalated by intercalating concave parts of the lens-frame assembling parts. Positioning slots on another sides of the lens frames are inserted by positioning bumps of the fixing parts in sliding slots of the glasses frame. Therefore, when the main spectacle frame or the lens frames are needed to be exchanged, it only needs to fiddle the fixing parts to separate the positioning bumps of the fixing parts and the positioning slots of the lens frames. Then, the lens frames can be removed from the main spectacle frame. The removed lens frames can be assembled with other main spectacle frames having other styles and colors.
