3 Terms
The following terms apply to this procedure.
3.1 refractor vertex standard equipment standarddevicesofvertexpowerforeyerefractometers
Verification of all types of standard device refractor spherical degree, degree cylinder, cylinder axial, IPD and other technical indicators called optometry
Instrument vertex standard device. Refractor vertex standard is divided into objective and subjective standards standards unit.
3.2 objective standards is objectivestandarddevices
Mirror Ball standard for verification of objective type refractometer, cylinder, cylinder lens axial, IPD and other technical indicators.
Including simulation objective standards eye, cylinder standard, a standard device IPD refractor.
3.3 Subjective standards is subjectivestandarddevices
Verification subjective formula for the standard device refractor spherical degrees. Subjective standards including analog and eye diopter cylinder.
3.4 objective standards model eye objectivestandardmodeleyes
Standard model eye test objective refractor style mirror ball is called the degree of use of objective standards model eye (called objective
Analog eye).
3.5 Subjective standards model eye subjectivestandardmodeleyes
Standard analog subjective eye test refractor style mirror ball of the formula used is called subjective standard analog eyes (referred to subjective
Analog eye). By the sight of the cylinder with the top power of a standard lens zero diopter mating together.
3.6 lenticular standard device cylindricalstandarddevices
Verification objective refractor type lenticular degree cylinder axial standard device used is called lenticular standard device. Lenticular standard
It consists of lenticular model eye (cylindricalmodeleyes) and axial controller (axialholder) components.
3.7 refractor IPD standard device pupildistancestandarddevices
Device characterization objective refractor type IPD IPD refractometer measurement function is called standard (hereinafter referred to as the standard IPD
Aligner).
