What is the difference between medical optometry and general optometry?

1, optometry standards are different

Ordinary optometry: generally refers to the optical dispensing optometry in the optical store, mainly refers to the refractive error of the person to see the object. Based on the computerized optometry to derive the number of refractive error, the operation method and steps are relatively simple.

Medical optometry: Medical optometry is the examination of the gathering of light rays into the eye, which is based on the state of the orthopic eye as a standard, and measures the degree of difference in the gathering and dispersion between the examined eye and the orthopic eye.

2, optometry process is different

Ordinary optometry process: measurement of naked eye vision - computerized optometry - lens box test method.

Medical optometry process: measurement of naked eye vision - computerized optometry - examination of the dominant eye - examination of eye position (strabismus, esotropia) - adjustment and fusion ability of the examination - collection and dispersion ability of the examination -Dilated pupils or comprehensive optometric examination - Trial lenses - Prescription.

3, equipment and personnel requirements are different

Medical optometry on optometry equipment and personnel requirements, the quality of its completion is closely related to the professional knowledge of the operator. Qualified medical optometry not only to do to see clearly, but also to obtain reading lasting, comfortable effect. Developed countries will be dispensing glasses as a strict medical behavior, before dispensing glasses must be medical optometry.

Extended information:

Most eyeglasses and hospitals rely only on computerized optometry and inserts to dispense glasses, which is called conventional optometry. Modern optometry emphasizes the use of medical optometry for patients, and medical optometry requires the use of a comprehensive optometric instrument.

When a myopic patient, wearing -3.00D corrective lenses, corrected visual acuity can reach 1.0, at this time, -3.25D, -3.50D, -3.75D, and -4.00D, these five corrective lenses can make the corrected visual acuity of 1.0.

If the conventional optometry, only in these five corrective lenses can only be selected one as the prescription for the prescription. But in medical optometry, it is not, it has to be based on the examinee's eye position, adjustment, binocular monovision and collection function and other examination results, can only choose one of the fixed lenses, and even can choose -2.75D as the final optometric prescription.

Thus, medical optometry and routine optometry have different meanings and contents. From the medical point of view, the purpose of wearing corrective lenses is not only to make the patient see clearly, but also to make him/her comfortable in wearing the lenses, as well as to treat some possible eye diseases, such as visual fatigue, occult inward or occult outward strabismus, etc., which is the basis of medical optometry.
