You can’t get glasses without measuring the pupillary distance.
Pupillary distance is a very important indicator when fitting glasses, if you don’t measure the pupillary distance accurately, it is impossible to check and fit the glasses reasonably, which will easily lead to visual fatigue and other symptoms after wearing the glasses.
Pupillary distance refers to the distance between the center of the pupils of both eyes of the patient, the pupillary distance factor should be fully considered when fitting glasses, so that the optical center of both eyes’ lenses coincide with the pupillary distance, so that the patient can accurately see through the center of the lenses to see things, if the pupillary distance is inappropriate, it will lead to the patient to look at the outside world from the edge of the lens, which will easily cause visual fatigue and other symptoms.
Patients should first go to the ophthalmology department of the hospital for examination, and then the doctor will issue a prescription to guide the patients for fitting.
