Description

Apparatus and method for processing eye-glass lens sharing eye examining data}

The present invention relates to an apparatus and method for processing a spectacle lens, and more particularly, to an apparatus and method for processing a spectacle lens capable of preventing an error in lens processing by sharing optometry data between an optometry device and a lens processing device.

In order to process a spectacle lens having a refractive power suitable for the user's eyesight, first, after measuring the refractive power of the eye to be examined using an ophthalmoscope, a number of trials having a refractive power similar to the refractive power measured using a phoropter After the lenses are alternately positioned in front of the user's eyes to create a state like wearing glasses, the user selects a lens that is suitable for his or her vision and has refractive power that is comfortable to wear. When a lens suitable for the user's eyesight is selected, the optician uses a lens processing device to select a circular lens (usually commercially available under the name “blank lens”) having the selected refractive power. In other words, it is processed into the shape of the frame.

1 is a view for explaining a process of measuring the refractive power of an eye to be examined using a conventional ophthalmoscope. As shown in Fig. 1, after the user 5 is located in the front of the ophthalmoscope 10, the ophthalmoscope 10 irradiates the measurement light into the eye of the user 5 and detects the signal light reflected from the retina of the eye to be examined. By doing so, the refractive power of the eye to be examined is measured by a different angle equation, and such an ophthalmic device 10 is generally referred to as a refractometer. 2 is a diagram for explaining a process of selecting a lens suitable for a user using a conventional phoropter. As shown in FIG. 2, the Phoropter 20 is a device that alternately positions a plurality of trial lenses having various refractive powers in front of the user's 5, and arranges a plurality of lenses on a circular disk, While rotating the disk, it is supposed to select a lens suitable for the user's vision (see Utility Model Registration 20-0391189). An automatic porter is a device that automatically rotates a disk equipped with a lens, and such an automatic porter is generally referred to as a digital reflector.

In the ophthalmic apparatus as shown in Figs. 1 and 2, the data of the eye to be examined obtained from the ophthalmoscope 10 or the Phoropter 20 is a small printing machine 12 provided on the side of the ophthalmoscope 10 or the Phoropter 20. Printed in and delivered to the optician. 3 is a diagram showing an example of optometric data printed by the ophthalmic device 10 or the phosphor 20. As shown in FIG. 3, the printed optometric data includes data such as spherical refractive power (SPH), circumferential refractive power (CYL), astigmatism direction (AX), and pupil distance (PD). The optician checks the printed data, selects a blank lens of the appropriate standard, and processes the selected blank lens according to the shape of the eyeglass frame. In this type of spectacle lens processing, the lens standard printed on the packaging of the blank lens and the actual lens standard are different, or due to an error of the optician, lenses with different specifications may be selected and processed. In this way, in the case of processing a lens that does not match the data of the eye to be examined, the lens cannot be used and should be discarded and reprocessed with a new lens. Since the appearance of blank lenses is all similar regardless of the standard of refractive power, etc., it is easy for the optician to select the wrong lens. If the wrong lens is selected when selecting the blank lens, there is no way to check this later, so lens processing errors are prevented. There is a disadvantage that is easy to occur.

An object of the present invention is to provide an apparatus and method for processing a spectacle lens capable of preventing a lens processing error that may occur due to an error in selecting a lens by an optician.

Another object of the present invention is to provide an apparatus and method for processing spectacle lenses that can check when a lens that does not meet the standard is selected.

It provides a spectacle lens processing device including the lens processing device 40.

In addition, the present invention, the step of generating optometry data by examining the eye to be examined; Converting the generated optometry data into digital data and creating a digital data medium recorded thereon; Reading the digital data medium to generate optometric data; Receiving the read optometry data, detecting a characteristic of a blank lens mounted on the lens processing device 40 by a user for lens processing, and then outputting the input optometry data and the detected characteristic of the blank lens together; And comparing the optometric data with the characteristics of the blank lens, and if the optometric data and the characteristics of the mounted blank lens are the same, it is determined that the correct blank lens is mounted and lens processing is performed, and the characteristics of the optometric data and the mounted blank lens are If different, it provides a method for processing a spectacle lens comprising the step of stopping the lens processing by determining that a blank lens of a different standard is mounted.

According to the spectacle lens processing apparatus and method according to the present invention, when a lens that does not meet the standard is selected, this can be checked, and lens processing errors that may occur due to an error in lens selection by an optician can be prevented.

The optometry device 30 is an ophthalmic or optician inspection device that inspects an eye to be examined and generates optometry data, and includes a refractometer, a phoropter, and the like. The refractometer is a conventional ophthalmological apparatus that measures the refractive power of the eye to be examined in a different angle by irradiating measurement light to the eye to be examined and detecting signal light reflected from the retina of the eye to be examined. The Phoropter arranges a plurality of trial lenses having various characteristics (refractive power, astigmatism axis, etc.) on a circular disk, and rotates the circular disk to sequentially place lenses having various characteristics in front of the eye to be examined, It is a general optometry device in which the user consciously selects a suitable lens for (see utility model registration 20-0391189). The optometric data generated by the optometry device 30 includes spherical refractive power (SPH; sphere), circumferential refractive power (CYL; cylinder), astigmatism direction (AX: axis), and ADD (presbyopia) of the eye to be examined, specifically the left and right eyes. The magnification factor applied to the lower part of the multifocal lens), a pupil distance (PD), and the like may be included to correct for. Since the standard (refractive power of the lens, etc.) of the lens processed by the lens processing device 40 is finally determined by Phoropter, in the spectacle lens processing apparatus according to the present invention, the optometry device 30 is preferably a Phoropter. Do.

The digital data medium generation unit 32 is a device that converts the optometry data generated by the optometry device 30 into digital data and generates a digital data medium recorded thereon. In the present invention, digital data means data that can be mechanically read by a mechanical device, specifically, a digital data medium reader 42 to be described later. The digital data medium is a medium in which optometry data values are recorded as digital data, for example, paper in which optometry data (refractive power values, etc.) of the subject to be examined is printed in the form of a barcode or QR code, a data file on which optometry data is recorded, etc. Can be illustrated. 5 is a diagram illustrating a paper on which a barcode or a QR code is printed as an example of a digital data medium generated by the digital data medium generation unit 32 of the present invention. In the example shown in FIG. 5, in the digital data medium 50, digital data corresponding to the numerical value 52 of the optometry data, together with a numerical value 52 of the optometry data that can be identified by a user, are stored in a barcode ( 54). As shown in Table 1 below, the digital data of the barcode 54 can also display a combination of each numerical value 52 of the optometry data as an index. Each data of the lens is usually 0.25 steps, R/L value (X, left/right identification value) is 1 digit of 0-1, SPH(XXX) is 3 digits of 0~200, CYL(XX) is Since 2 digits 0~80, AX(XXX) 3 digits 0~179, ADD(XX) 2 digits 0~40, INDEX is given for each data combination as shown in Table 1 below. And, it is possible to generate the barcode 54 by using the assigned INDEX. Alternatively, a numerical value representing each data item (eg, SPH = 1, CYL = 2, etc.) and a numerical value of the corresponding data item may be displayed as barcode values 54 in order.

[Table 1]

When the digital data medium is a barcode or a paper printed with a QR code, the digital data medium generating unit 32 may be a conventional printer capable of printing a barcode or a QR code, for example, shown in FIG. It may be a small printing machine 12 attached to the ophthalmoscope 10 as described above. When the digital data medium is a data file in which optometry data is stored, the digital data medium generator 32 may be a microprocessor capable of generating a data file. The digital data medium generation unit 32 may be integrally formed with the optometry device 32.

The digital data medium reading unit 42 is a device that reads the digital data medium generated by the digital data medium generation unit 32 to generate optometric data. For example, when the digital data medium generation unit 32 is a printer that prints a barcode or a QR code, the digital data medium reading unit 42 is a barcode or a barcode capable of reading the barcode or paper on which the QR code is printed. It is a QR code reader. When the digital data medium generating unit 32 is a microprocessor that generates a data file, the digital data medium reading unit 42 is a microprocessor that reads the data file. When the digital data medium is paper on which a barcode or a QR code is printed, the digital data medium may be physically transferred to the digital data medium reader 42 by a user (glass processor). On the other hand, when the digital data medium is a data file, the digital data medium may be transferred to the digital data medium reading unit 42 by wired communication using RS232 or the like or wireless communication referring to WIFI.

The lens processing device 40 receives the optometric data read from the digital data medium reading unit 42, detects the characteristics of the blank lens mounted by the user in the lens processing device 40 for lens processing, The input optometry data and the detected blank lens characteristics are output together. The user compares the output optometry data and the characteristics of the blank lens, and if the optometry data and the characteristics of the attached blank lens are the same, the user determines that the correct blank lens is mounted and performs lens processing, If the characteristics are different, it is determined that a blank lens of a different standard is mounted, and the lens processing is stopped. For example, through a monitor mounted on the lens processing device 40, whether or not the optometric data and the characteristics of the mounted blank lens match or error may be displayed through a pop-up window.

The lens processing device 40 is a lens processing device for processing a blank lens, and includes lens processing equipment such as a lens meter, an automatic blocker, a semi-auto blocker, an edging equipment, and a lens edger. The lens meter is a conventional device that detects physical characteristics such as refractive power of the lens and marks the center or in-point (optical center point) of the lens, and the blocker detects the center or in-point of the blank lens. , It is a general lens processing apparatus that mounts a block for processing a lens at the center or in-point of a blank lens, and the edging equipment and lens edger measure lens characteristics such as curvature of the lens, and measure the edge of the lens. It is a general polishing apparatus for processing into the shape of an eyeglass frame. The digital data medium reading unit 42 may be integrally formed with the lens processing device 40. For example, a barcode reader, which is one of the digital data medium reading unit 42, may be mounted on the lens meter itself, which is the lens processing device 40. For example, it is possible to confirm whether the lens to be processed by the lens meter is a correct blank lens by checking whether the data of the blank lens detected by the lens meter (such as a Diopter) and the optometry data obtained by the optometry device 30 match.

If the optometry data of the eye to be examined obtained from the optometry device 30 is shared with the lens processing device 40, it is easy to check whether the optometry data of the eye to be examined and the lens data (diopter, etc.) match, and to process the wrong lens. Can be prevented.
