DEVICE FOR MEASURING PARAMETERS FOR LENS PRESCRIPTION

摘要

The object of the present invention is to provide a device for measuring parameters for lens prescription, in which a subject for an eye examination is induced to see near and distant objects when the subject wearing an eyeglass frame mounted with a ruler which provides the standards of length is positioned in front of a main body, the figure of the subject is continuously photographed in two directions by two cameras incorporated in a machine, and parameters required for lens prescription are analyzed from the total four digital images which are obtained by the cameras. According to the present invention, the rotation point of each eyeball as well as data such as distance PD (Pupillary Distance), near PD, and the like are extracted by precisely photographing the far point and near point of pupils using the two cameras. Thus, the lenses to be prescribed for patients are precisely designed.
