 Rotary Prism
This high-end Ezer refractor allows for vertical and horizontal measurements of 0 to 20∆ in 1∆ steps. It has also a click stop that permit you to measure horizontal and vertical strabismus and heterophoria.

 Adjusted Cylinder Power and Axis
The cylinder lens graduated in 0.25D steps allows adjustments from 0 to -6.00D and with the accessory lens -2.00D, it is posible to extend adjustment range up to -8.00D in 0.12D. The cylinder axis can be adjustment up to 0° ~ 180° in 5 steps. Each adjustment can be made rapidly with two snobs on the same axis.

 Cross Cylinder
The cross cylinder loupe rotates automatically through a special syncronized mechanism with the control knob, to change the cylinder lens axis. The cross cylinder knob on the ERF-5200 is conveniently synchronized with the cylinder axis knob. For even greater precision in wider ranges, ±0.37D and ±0.50D cross cylinder lenses are available.

 Corneal Alignment Device
It is used to align the corneal verted of the patient and set the patient’s cornea in the correct position (at 12mm from the view tester lenses). Measurement should be made at the "0" position of the scale.

Convergence System
Precise measurement is possible with the lens set at a suitable angle for near vision testing (by closing the convergente lever inward) as well as for distance (by opening it outward).
This converges the optical system coincident to the convergence of the patient’s eye while the patient looks througth the correct optical centers. Therefore, this unique system enseres perfect testing.

 Adjusting Sphere Power Readings
The ERF-5200 comes standard with a pair of -2.00D auxiliary cylinder lenses, as well as a pair of -0.12D auxiliary cylinder lenses. Optional accessories include +10.00D, -10.00D and +2.50D (for retinoscope) auxiliary spherical lenses, as well as ±0.37D and ±0.50D cross cylinder lenses.
Spherical power ranges from -19.00D to +16.75D to -10.00D in 0.25D steps. By using the unit's auxiliary lens, you can measure -29.00D to +26.75D in 0.12D steps. For speed and convenience, sphere power can be changed in 3.00D steps by turning the spherical power quick forwarding dial.

 Near Point Scale and Chart
The scale can be graduated in "Inches", "Centimeters" and "Diopters". It can be set at distance you like to use and when it is not in use, it can be stored in a standing position.
The Near Point Chart contains a notable disc with 12 kinds of test on both sides. The scale is 26.4in length.
