PURPOSE OF USE
Used to measure the refractive power of eyes and perform the binocular function test.
OPERATION PRINCIPLE
On a disk built in the instrument, the lenses with a variety of refractive power are arranged. By
turning the disk, the lenses are changed to each other. There are two or more disks in the
instrument. So, measurement of different types can be carried out by selecting and combining
the disks.
