How to use
1.Display screen
Pic .3 is the display screen. The readings on the left are for the right eye, while the readings on the right are for the left eye. They are (from top to bottom):
Curvature radius of long axis (or diopter) of long axis
Curvature radius of short axis (or diopter) of short axis
Axial angle: (unit: degree)
Measurement times
Mean variance of curvature radius (or diopter) of long axis
Mean variance of curvature radius (or diopter) of short axis
Collected data has two way of display: the radius of curvature display and refraction display. Click both left and right button to switch.
