## Background
FIELD OF THE INVENTION
The present invention related to an ophthalmic instrument system, and more particularly to method for controlling ophthalmic instrument for eye examination.
DESCRIPTION OF THE RELATED ART
A phoropter (US trademark of Reichert Technologies)) is an instrument commonly used by eye care professionals during an eye examination, containing different lenses used for refraction of the eye during sight testing, to measure an individual's refractive error and determine his or her eyeglass prescription.
The phoropter includes a plurality of lenses such as spherical lenses, cylinder lenses, etc. which are combined for eye examination.
In addition, the phoropter performs eye tests such as eyesight test and color blindness test together with another ophthalmic instrument, a chart projector.
As a phoropter there are two types, a manual phoropter manually operated by rotating dials, and auto phoropter (digital refractor) automatically controlled by an operation panel.
But the whole cost for the digital refractor is high because the operation panel is necessary for the control of the digital refractor. Furthermore it is difficult to use an auto chart instrument of the other maker due to the compatibleness problem between the operation panel.
In addition, since the measurement data measured by the respective ophthalmic instruments cannot be transferred therebetween, the measurement data may be given by the display or the printed paper and cannot be saved, which makes integrated management and post management for the measurement data difficult.
