Refractometer Technology Is Easier To Learn And Master
Jun 09, 2017

Refractometer light is to check the light incident after the eyeballs gathered, it is the state of the eye as the standard, measured by the eye and the angle of view between the degree of dispersion. Because many people in life, almost all and glasses, therefore, the current optometry optometry workers are the most basic, the most common but important work, so the term optometry, in social life, Regardless of ophthalmologist, or ordinary people, are very familiar with.

1 optometry principle

Computer optometry is an objective optometry, the principle and retinal retinoscopy is basically the same, the use of infrared light source and automatic fog as the device to relax the eye to adjust the purpose of using optical technology and automatic control technology to check the diopter.

Subjective optometry and objective optometry can accurately measure the patient's refractive power and astigmatism axial. These two methods need a wealth of experience in optometry, in the mastery of retinoscopy technology takes a long time, and computer optometry technology easier to learn and master.

Computer optometry instrument optometry for flexible corneal contact lens can be used for diagnostic optometry, both without mydriasis can quickly measure the degree of refractive. Computer optometry instrument optometry results are all automatic printing, without conversion, usually a few seconds to a few minutes to determine a patient, and can quickly determine the degree of refractive error, for the lens correction to provide more accurate refractive power and distance between the pupil The

2 optometry accuracy

Of course, the accuracy of the computer refractometer by a number of factors, such as the patient's head and eye with the bad, moving to move, eye refraction within the refractometer target is not enough, so that relaxation is not enough, will inevitably affect the accuracy of refraction test results Sex, or even repeat the degree of the difference between the larger. For children and refractive interstitial turbid patients, computer refractometer test error is large, or even can not check the diopter. Therefore, the computer to determine the refractive power, as the only basis for the glasses is not appropriate. Computer refractometer can not replace the retinographer optometry and lens correction technology, only to provide a useful reference for artificial optometry.

As the computer refractometer can quickly measure the general situation of refractive errors, to understand the extent of consumer refractive and a large number of outpatient optometry can provide a useful reference.
