The following is the necessary process of optometry: consultation-computer optometry-old mirror test-pupil distance measurement-comprehensive optometry-insertion audition-photometric adjustment-optometry prescription.
First, consultation:
First of all, the customer's past glasses, wearing habits, working environment, working distance, eye habits and related accompanying symptoms, history of eye surgery or injury, history of other eye diseases, etc. , so as to fully understand the customer's visual health needs and the purpose of glasses. (You can drop one or two eye drops to relieve fatigue before the exam. )
Second, computer optometry:
Approximate data of preliminary measurement for reference.
Third, the old mirror test:
Naked vision (test with glasses)
Four, pupil distance measurement:
The optical center of the lens matches the pupil of the human eye.
Five, comprehensive optometry:
The lowest luminosity to ensure the best vision of one eye.
Accurate measurement of astigmatism axis and astigmatism with crossed cylindrical mirror.
The red and green test ensures that the degree is not correct.
Balance your eyes so that they can see clearly and harmoniously.
Sixth, try on the insert.
Try it on for about 10-20 minutes. Ask about any discomfort and other needs.
In the first picture, if you see every dotted line in the picture during the test, some dotted lines are clear or dark, and some dotted lines are fuzzy or white, then you may have astigmatism.
In the second picture, if you see that the red color in the picture is much clearer than the green color, it means that the glasses you are wearing now may not have enough degrees, or your degrees have increased now!
If you see that the green color in the picture is much clearer than the red color, it means that the glasses you are wearing now may have a high degree, or your current degree is relatively light!
Seven, photometric adjustment:
After trying on the insert, understand the customer's feelings when trying it on, and ask if there is distortion or blurred vision, dizziness, nausea and other phenomena. , and make appropriate adjustments and analysis according to customer feedback.
Eight, prescription:
According to the customer's original glasses, make corresponding adjustments according to the eye needs, occupation, working environment, living habits, etc., and prescribe glasses suitable for customers.
