Digital Refractor Phoropter
|
The comprehensive refractor first appeared as an instrument to check the function of the extraocular muscles. It checks the concentration of light after entering the eyeball. It uses the state of the emmetropia as the standard to measure the difference in vergence and dispersion between the inspected eye and the emmetropia. |
