Hereinafter, embodiments according to the present invention will be described with reference to the accompanying drawings. In adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are assigned to the same components as much as possible even though they are shown in different drawings. In addition, in describing an embodiment of the present invention, if it is determined that the detailed description of the related well-known configuration or function interferes with the understanding of the embodiment of the present invention, the detailed description thereof will be omitted. In addition, embodiments of the present invention will be described below, but the technical spirit of the present invention is not limited thereto and may be variously modified and modified by those skilled in the art.

Throughout the specification, when a part is "connected" to another part, this includes not only "directly connected" but also "indirectly connected" with another element in between. . Throughout the specification, when a part is said to "include" a certain component, it means that it can further include other components, without excluding other components unless specifically stated otherwise. In addition, in describing the components of the embodiments of the present invention, terms such as first, second, A, B, (a), and (b) may be used.

1 illustrates a near focus provided to both eyes of a subject when the subject is looking at a target object disposed at a short distance.

According to FIG. 1, when the measurement target looks at the target object 10 located at a short distance, that is, at a close distance, the distance between the pupils of both eyes 20, that is, the pupils 20, of the measurement target is the target object 10, that is, the target object 10. The so-called "pupillary phenomenon" occurs while gathering toward the near focus 30. This pupil distraction occurs when a person looking at an object located at a short distance, for example, about 1 to 5 meters (m), is reading or looking at an object in his or her hand. It does not occur when there is no object that is normally viewed, i.e., the object placed at a long distance or specially viewed. Therefore, in manufacturing the spectacle lens of the measurement subject, the first consideration should be that the eye passes from both eyes in the normal state of the measurement subject, i.e., in the state of looking at a long distance or an infinite distance without the occurrence of the above-mentioned pupillary phenomenon. Identify the lens area.

However, in order to provide a long-range or infinity focus to a subject to be measured, the target object must be placed at a far distance from the subject to be measured, and thus there is a problem in that it is limited to a measurement site and a large apparatus must be used. In the case of using the target object, as described above, pupillary phenomenon occurs in both eyes of the object to be measured, so accurate measurement is impossible.

In order to solve the above problems, the present inventors use the target light source and the infinite focus lens to provide the subject to be measured as an infinite distance focusing the effect as if looking at the target object disposed at a distant or infinite distance. On the other hand, in the present specification, the distance within about 1 meter (m), specifically about 50 centimeters (cm) from the measurement object, collectively referred to as "near distance", and farther than that, about 5 meters (m) from the measurement object Outside distance or infinite distance is collectively referred to as "infinite distance", but the protection scope of the present invention is not limited by the generic term for such a distance concept.

3 is a functional block diagram of a remote parameter measuring apparatus according to an embodiment of the present invention.

That is, the target light source 212 disposed at a short distance is seen as an object disposed at an infinite distance in both eyes 20 of the measurement target. As a result, although the target light source 212 is disposed at a short distance, the subject to be measured substantially looking at the target light source 212 is in a state of looking at an infinite distance, so that the pupil tilting phenomenon occurs in both eyes 20 of the subject to be measured. It does not occur, and the normal binocular pupil state as usual is maintained.

The light reflection point may be used to measure the distance between the eyes of the subject, the distance between the pupil distance of the eye, and the distance between the eyes of the subject. Can be a reference point. The light emitting unit 230 may be variously implemented to perform the function, but preferably, may be a light emitting diode (LED) light emitting device, specifically, a flash light emitting diode device, an infrared light emitting diode (IR) light emitting device, or the like. .

As such, according to the remote parameter measuring apparatus 200, the apparatus 200 is disposed in front of both eyes of a subject to be measured, and provides light from the target light source 212, but the light passes through the infinity focus lens 214. The subject then sees the infinite focus without pupillary. Thereafter, when the measurement target person looking at the infinite distance focus is photographed using the camera unit 220, a photographing image of the face of the measurement target person may be obtained, and the measurement parameter of the spectacle lens manufacturing parameter of the measurement target person is measured based on this. can do.
