Embodiment Construction

[0031] Preferred embodiments of the optometry frame of the present invention will be described in detail with reference to the drawings.

[0032] figure 1 and figure 2 According to one embodiment of the optometry frame of the present invention, figure 1 It is an explanatory diagram of the base frame that constitutes the optometry frame, figure 2 It is an explanatory diagram of the test frame that constitutes the optometry frame.

[0033] [pedestal]

[0034] figure 1 Among them, (a) is a plan view of a base frame (base frame) 1, and (b) is a front view.

[0035] The base frame 1 includes left and right temples 11 and a half-frame front frame 10 connecting the left and right temples 11 . The temples 11 are installed in a freely foldable manner through end pieces 13 and hinges 12 provided at the ends of the mirror frame 10 .

[0036] The temples 11 and the mirror frame 10 can be made of materials commonly used in spectacle frames, such as metals such as titanium and s...

Abstract

To overcome the problem of requiring a large number of optometry frames to match the pupillary distance of a subject, and the problem of decreased examination precision due to flexing of a front frame. An optometry frame (F) having left and right test lenses (25) retained in a front frame (10), wherein the optometry frame (F) has a base frame (1) having left and right temples (11) and the front frame (10) for connecting the temples (11), a test frame (2) provided with a lens holder (21) for retaining the test lenses (25) so that the test lenses (25) are replaceable, and attachment / detachment means (14, 24) for making the test frame (2) attachable to / detachable from the front frame (10). A test frame (2') may be divided at the center thereof into left and right portions. A test frame (2'')may have an adjustment means (23) for matching the interval between the left and right test lenses (25) retained in the lens holder (21) to the pupillary distance of a subject.

Description

technical field [0001] The present invention relates to an optometry frame for visual acuity tests performed at eyeglass stores or ophthalmology departments of medical institutions. Background technique [0002] When performing a vision test in a hospital ophthalmology department or an optical shop, etc., a plurality of test lenses with different diopters are prepared in advance, and the examinee wears a test frame that can detachably hold the test lens. The test lens is replaced with a test lens with a different diopter, and the lens with the diopter most suitable for the above-mentioned subject's eyesight is determined. The prescription frame includes a front frame having the same form as the spectacle frame and having left and right lens holders holding the test lens, and temples provided at both ends of the frame. And, by hanging the above-mentioned mirror legs on the left and right on the ears and putting the above-mentioned optometry frame on the face of the examinee,...
