Background
In the fitting process of the glasses, the interpupillary distance and the pupil height need to be measured. The pupil distance refers to the horizontal distance between the pupil center points of the two eyes of the subject; the pupil height refers to the vertical distance from the pupil center point of the subject to the inner edge of the circle of the lower edge of the selected frame when the selected frame is worn by the subject.
The existing popular methods for measuring pupil height are divided into three categories: firstly, when a mark pen is manually used to mark that a person to be examined wears the spectacle frame, the pupil center point is positioned at the position of the spectacle frame support sheet, and then the vertical distance from the mark point to the inner edge of the lower circle of the spectacle frame is measured by using the graduated scale. The method depends on the operation skill and experience of an operator, and has poor accuracy of measured values and poor stability of repeated measured values.
Secondly, auxiliary tools are used on the spectacle frame selected by the examinee, such as adding a scale adhesive film patch on the support sheet of the spectacle frame; or after the support sheet is detached, placing a rubber scale card in the lens circle and reading the horizontal and vertical positions of the pupil center point of the examinee in the lens circle, namely the pupil distance and the pupil height; and then or the pupil measuring device is hung on the selected frame of the detected person from the upper part and two sides, the scale marks are respectively made to pass through the pupil center point of the detected person in the horizontal and vertical directions through the adjustment of a horizontal and vertical scale mark knob, and the scale value at the moment is read to obtain the pupil distance and the pupil height. The adhesive film patch in the method belongs to consumable materials, and has inconvenient positioning and lack of positioning reference during pasting; the glue scale card has the style limitation of being suitable for the spectacle frame, and only can be suitable for the full-frame spectacle frame, but the half-frame spectacle frame and the frameless spectacle frame cannot be used; the knob clamp type pupillometer is relatively complex in structure and heavy in weight, and when the pupillary pupil is clamped on a spectacle frame selected by a subject, the pupillary pupil is easy to slide down due to the weight, so that the pupil height measurement is possibly deviated.
Thirdly, by means of shooting and digitalizing, namely shooting a picture of the person to be detected wearing the selected spectacle frame and digitalizing the picture, measuring the horizontal and vertical positions of the pupil center point of the person to be detected on the spectacle frame supporting sheet on the contrast sheet, and obtaining the interpupillary distance and the pupil height. The method can well measure the interpupillary distance and the pupil height by utilizing shooting and computer digitization technology, but the manufacturing cost is relatively high.
