[Problem] 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. [Solution] 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.
