1. The optometry standard is different. If you think that optometry is to test the eye chart, and then look at the "small house" and "hot air balloon" on a machine to measure myopia, it is wrong! General optometry: allows people with ametropia to see objects clearly and ignores the evaluation of binocular visual function. Medical optometry: distinguish true and false myopia, strabismus, amblyopia and other eye developmental diseases, control diopter development, improve visual quality, and establish perfect binocular visual function. 2. Different optician procedures, general optometry: naked eye vision measurement-computer optometry-insertion audition. Medical optometry: computer optometry-naked eye examination-intraocular pressure examination-slit lamp and eye position examination-axial position measurement-comprehensive optometry-adjustment function (positive and negative relative, adjustment response)-audition-mydriatic optometry. 3. Different characteristics of glasses General optometry: optometry is simple and fast. Medical optometry: scientific, stable and reliable, which can protect vision health to a great extent.
