Description

[0001] Optometric apparatus [

The present invention relates to an ophthalmologic apparatus, and more particularly, to an ophthalmologic apparatus which comprises a lens disc and a cover unit which are moved or rotated by moving a pair of lens discs in the body during a single- To an optometric apparatus capable of preventing damage or psychological anxiety of the subject in advance.

The optometric apparatus is a mechanism for measuring the visual acuity of the examinee or examining the state of the eye, and a method of selecting a lens suitable for the visual acuity of the examinee while arranging a plurality of lenses sequentially in front of the eye of the examinee is used.

In the initial stage, after a wearer wears a frame made in the form of an eyeglass, a worker inserts a plurality of trial lenses at positions corresponding to the eyes of the subject in the frame, or inserts a plurality of trial lenses to inspect the visual acuity of the subject, The device was used.

However, such passive optometric apparatuses require the operator to arbitrarily select the trial lenses. In addition to this, it takes a considerable amount of time to select appropriate lenses, and a difference in the selection of the trial lenses is caused according to the skill of the operator. A problem that the proper lens can not be selected has arisen.

In order to solve such a problem, an automatic optometric apparatus has been developed and used which automatically rotates a circular disk provided with a plurality of trial lenses to select a trial lens suitable for the visual acuity of the subject.

FIG. 1 is a front view showing a conventional automatic eye examination apparatus, and FIG. 2 is a perspective view showing a conventional lens disk.

1 and 2, the conventional automatic optometric apparatus 100 includes a main body 110 and a plurality of rotating disks coupled to a lower portion of the main body 110 and rotated to measure a visual acuity of the subject A pair of lens discs 120 and a lens L provided in the lens disc 120 to surround a pair of lens discs 120 on the outside of the pair of lens discs 120, A pair of cover parts 130 each having an optometric hole 131 formed on one side thereof and a forehead support 140 extending rearward from one side of the main body 110 and supporting the forehead of the subject.

In this conventional automatic optometric apparatus 100, in a state where both eyes are positioned in an optometric hole 131 formed in a pair of cover portions 130 while the subject supports the forehead on the forehead support 140, The test lens 120 is rotated to measure the visual acuity of the subject by overlapping the trial lenses according to the distance from the pupil of the examinee.

The conventional automatic optometric apparatus 100 includes a pair of lens discs 120 so as to precisely arrange the trial lens L in front of both eyes of the examinee according to the distance between the eyes and the pupil of the examinee, The pair of cover parts 130 are moved in the left and right direction and are installed to be rotatable in the forward and backward directions, so that the visual acuity of the subject can be easily measured.

Meanwhile, in the conventional automatic optometric apparatus 100, the eye of the examinee has a difference in distance from the nose to the both eyes according to the person's nose. In order to reduce the comfortable wearing comfort of the eyeglasses and eye fatigue, And a monocular pupil distance (MPD) measurement function which is a distance from the nose to any one pupil.

However, according to the conventional automatic optometric apparatus 100, monocular PD measurement is performed in a state in which the subject's forehead is supported on the forehead support 140, and the single-eye PD is measured according to the position of the forehead supported on the forehead support 140 by the subject. The measurement reference is displaced and the position where the forehead is supported on the forehead support 140 is determined as the center of the nose and the monocular PD is measured based on the position of the nose.

In addition, the conventional automatic optometric apparatus 100 has a pair of lens discs 120 and a pair of cover portions 130 in front of the examinee's eye in accordance with the distance between the examinee and the pupil at the time of eye examination or monocular PD measurement The lens disk 120 and the cover portion 130 driven by the left and right movement and the left and right rotation do not often cause injury to the subject while colliding with one side of the examinee's face, Even if the subject 130 does not collide with the face of the examinee, the subject is disturbed by the movement of the examinee's eye, resulting in psychological anxiety.
