Product Description
This New updated Phorpter has top qualit y and we work with Essilor .
very delicate ,every piece glass we do several times cleaning to make sure its high precision .

It has wide measureing range, its range of standard cylinder lens can reach up to 6D with the revolution 0.25D. In the range of 20, accuracy will be lower than 0.5, using the rotary prism with trimming gear.
And P. D. Can be adjusted from 48mm to 75mm, quick switch between near P. D, between near visual angle and far visual angle.

Synchronal cross cylinder: Rotating of the cross cylinder is synchronal with the adjustment of the cylinder axis.
Convenient operation, clear scale: With the special design, you can switch to the appropriate lens quickly.
Multifunctional auxiliary lens: This multifunctional auxiliary lens includes: Red-Green lens, polarizer, prism, stenopeic lens, etc.
Fast and accurate conclusion: There are two spherical lens turntables with 0.25D and 3D diopter steps.
Measuring range: +16.75D~0~-19D. You can adjust it much more accurately if you use the 0.12 auxiliary lens.

Item  and  range  of  measurement:
Myopia:0  to  -19.00  diopter  in  0.25  diopter  step  (0.12  diopter  step)
Hyperopia:0  to  +16.75  diopter  in  0.25  diopter  step  (0.12  diopter)
Astigmatism:0  to  -6.00  diopter(-8.00  diopter)  in  0.25  diopter  step
Phoria  and  vergency:20  to  0  to  20  by  1  step; Inner  40; Outer
Near  vision  test:Main  optical  axes  of  both  lenses  converges  by  means  of  a  tilt  mechanism  at  40cm  in  front  of  the  eyes  at  64mm  P. D.   If  P. D.   for  far  vision  is  less  then  54mm, converging  operation  stops.
Binocular  balance  test:Rotary  prism  and  polarizing  lens  methods  are
P. D  :48  to  75mm  by  1mm  step
Level  adjustment:More  than  4.5  for  right  and  left  banks

WMH:White  Maddox  rod  is  set  horizontally.
RL:Red  lens.
GL:Green  lens.
PH:A  1mm  diameter  pinhole  is  provided. This  lens  is  used  to  determine  if  Poor  vision  is  due  to  refractive  abnormality  or  other  caused.
