される傾向にあつた。``Prior art and its problems'' There are various methods for optometry, including subjective and objective methods, and each method and device is used according to its purpose and application. BACKGROUND ART A subjective optometry method in which an examinee attaches and detaches an optometric lens to a test frame is widely used as a natural and simple method. The main reason for this is said to be that it causes less tension and discomfort to the examinee, and that it is easier to perform eye examinations in a natural state that eliminates the accommodative power of the human eye. In order to ease the tension on the subject and reduce the discomfort, it is further desirable that the test frame be lightweight and to minimize the feeling of pressure on the subject's nose, ears, etc. However, the test frames currently in use are for subjects who require very strong correction (such as those who have had their crystalline lens removed due to cataracts), and subjects who require special correction (such as prism lenses for correction of tropia). In order to enable eye examination of various patients with farsightedness, myopia, and even astigmatism, including patients with long-sightedness (requiring a prescription), many lenses have a structure in which three or more lenses are attached to each eye, and are therefore lightweight. Sex and freedom of pressure tended to be sacrificed.

The frame 11, which has a shape similar to a general eyeglass frame, has temples 12, 12 on both sides thereof, and two guide pins 14, 14 and a holding pin around the circular left and right lens openings 13. A spring 15 is fixed. The guide pin 14 has, as shown in FIG.
A plurality of lens frame support grooves 16 are formed at regular intervals l in the longitudinal direction. The retaining spring 15 is the ninth
As shown in the figure, it has a substantially U-shaped cross section with the opening facing toward the center of the lens opening 13, and a locking convex portion 15b is provided at the tip of the spring side wall 15a.

レンズを装着できるようになつている。 When performing an eye examination on a general subject, we begin by examining the basic and rough stages of whether the subject is nearsighted or farsighted, and then examine the near (far) vision power, the astigmatism power, and the degree of astigmatism.
Furthermore, confirmation and testing of astigmatism in the axial direction is progressing.
A prescription is created. When determining the power of near (far) vision and astigmatism, the basic optometry lens 20, which is considered to be almost the target, is combined with various weak optometry lenses 20 that correct the basic power. A method is mainly used to determine the final power of the corrective lens after detailed confirmation. The plurality of lens frame support grooves 16 and the plurality of holding springs 15 formed on the guide pin 14 are for making this overlapping possible.
The two optometric lenses 20 are stacked one on top of the other.
For these reasons, conventional test frames are designed to accommodate three or more lenses.

によつては、さらに補正を必要とした。 However, in this conventional test frame, the interval l (Fig. 8) between the lens frame support grooves 16 is set large so that the thickest lens (high power lens) can be inserted and removed. Optometry lens 20
as a result of moving away from the subject's face. For this reason, using the contact area between the test frame and the bridge of the nose on the face as a fulcrum,
The weight of the lens increases the moment when the test frame tends to fall forward, which not only causes strain and discomfort on the subject, but also causes the test frame to easily fall off the face during the eye examination. In addition, the prescription of corrective lenses for eyeglasses is performed on the premise that the lenses are positioned at a predetermined distance from the corneal apex of the eye (even if the same lens is worn at different distances, the corrective effect on the eye may differ. In the conventional product described above, the distance between the stacked optometric lenses 20 is naturally large, so when prescribing particularly strong lenses, it is necessary to pay attention to the error in this distance, and in some cases , which required further correction.

眼の誤差を少なくすることができる。 Therefore, according to the present optometry test frame having the above configuration, the lens frame support grooves 33 of the three groove blocks 33
a and the holding spring 35, it is possible to support the optometric lens 20 in the same manner as in the conventional product, and furthermore, the supported optometric lens 20 can be brought as close to the frame 11 side as possible. That is, the groove block 33 and the retaining spring 35 are compressed by the compression spring 34.
and compression spring 36, the lens body 22 of the optometry lens 20 is biased to move in the direction approaching the frame 11, so that even if the thickness of the lens body 22 of the optometry lens 20 is large or small, the overlapped optometry lens 20 always has a part (Usually the lens body 22) comes into contact with each other. Therefore, the moment caused by the weight of the stacked optometric lenses 20 that causes the frame 11 to tilt forward can be significantly reduced, reducing the burden on the examinee and minimizing tension. It is possible to perform eye examination in a more natural state, and it is possible to prevent accidents in which the test frame inadvertently falls off. Furthermore, errors in optometry due to the position of the optometry lens 20 being away from the eye can be reduced.

検眼の精度および信頼性を高めることができる。 Further, according to the above embodiment, since the groove block 33 is rotatable around the groove block guide pin 31, the optometric lens 22 can be rotated, especially for measuring the astigmatic axis.
The rotational torque when rotating 0 is significantly reduced. Therefore, it is possible to reduce the pressure applied to the bridge of the examinee's nose, thereby reducing the discomfort that occurs during eye examination (feeling as if a force is being pushed from the side), and by extension, reducing the pressure exerted on the bridge of the examinee's nose. Reduces the accommodation forces produced,
Accuracy and reliability of optometry can be improved.

Since it is biased to move, it can be moved as close to the frame as possible depending on the thickness of the optometric lens. As a result, the moment exerted on the frame due to the weight of the optometric lens can be reduced, minimizing the burden on the examinee, especially the burden on the examinee's nose, without making the examinee nervous. , it is possible to perform subjective eye examination under more ideal conditions. Furthermore, since the distance between the optometry lenses can be set to the minimum, the accuracy of optometry can be improved.
