Test The Use Of The Frame

The test frame is one of the basic tools of optometry, which must be used every time the insert optometry. It has a frame in the form of eyeglasses, and two audition seats are arranged on the front of each of the two circles of the frame. The test frame is used after the main vision optometry is performed by the comprehensive optometer. Although the results obtained by the comprehensive optometer are more accurate, the test frame technology must be adjusted appropriately, because the test frame is closer to the actual wearing situation than the comprehensive optometer.

The test frame is very important in the optometry process, and the placement of the test lens is also very particular, to ensure that each lens of the monocular is in an optical coaxial state, so the production must be standardized.rget projection area correctly, and cannot be completely relaxed and adjusted. The inspection results are not accurate enough, so it has not been widely promoted.

With the development of electronic computers, there have also been new developments in objective optometry.
