2. If you suffer from myopia, you should use the myopia lens used in hospital optometry when measuring corrected vision, instead of your own myopia glasses or contact lenses.
The standard logarithmic visual acuity chart was used for vision examination, and the examination results were recorded by 5-point recording method. Anyone whose naked eye vision is less than 4.8 needs to be examined with corrective lenses, and those whose correction is less than 4.8 should have their eyes examined. If the fundus only sees myopia features without other abnormalities, hyperopia can be improved by increasing the lens power. Corrected vision and degree of correction can be recorded in the physical examination form.
