With glasses, how to choose glasses frames and lenses? What common sense or skills are there?

Glasses are the same as clothes. Glasses with a few dollars in the market are the same as clothes supported by Jin, so the factors that determine the quality of glasses are brand and price. I'll write it according to the optician's process. Here, we only talk about cheap glasses on the market. First of all, don't choose to wear glasses on holidays or during periods of heavy traffic. A pair of glasses normally optometry about 15 minutes, try it on for 1 to 2 minutes. It takes more than 2 minutes to make lenses. Therefore, the whole process will take at least 45 minutes, so if some shops are busy, the optometry time will be reduced accordingly. Originally, one pair will be made in 2 minutes, and when there are many people, three pairs will be made in 2 minutes. So the corresponding quality is different. In addition, optometrists also need to be verified. My friend has been an optometrist for 9 years. When he was working in his old employer, he was responsible for training new employees on optometry. Generally, after more than a month of training, the boss would buy a certificate and hang it in the shop. So pay attention to the optometrist in the optical shop when you wear glasses. Mirror frames can be roughly divided into metal, plate and natural materials. (The most expensive one is natural tortoise shell series) Among them, titanium alloy has high strength and is relatively light. The choice of the frame should be based on your own preference, and be careful not to choose the one that is easy to deform, because if you have astigmatism, the deformation of the frame will affect the axial position of the lens.

the following is the necessary process of optometry: consultation-computer optometry-old lens test-pupillary distance measurement-comprehensive optometry-insertion audition-photometric adjustment-prescription

1. consultation:

First of all, the customer's past wearing of glasses, wearing habits, working environment, working distance, eye habits and related companions are analyzed. (One or two drops of eye drops can be used to relieve fatigue before the test)

Second, computer optometry:

Preliminary measurement of approximate data for reference.

Third, the old lens test:

naked eye vision (wearing glasses test)

Fourth, pupil distance measurement:

Make the optical center of the lens match the pupil of human eyes.

Fifth, comprehensive optometry:

Ensure that one eye can get the best vision and the lowest luminosity.

cross cylindrical mirror accurately measures the axial position and degree of astigmatism.

red and green test to ensure that the degree is not too correct.

eyes are balanced, so that both eyes can see clearly and harmoniously.

6. Try on the insert.

try it on for about 1-2 minutes. Asking about discomfort and other needs

In the first picture, if you see every dotted line in the graph during the test, some dotted lines are clear or black, and some dotted lines are fuzzy or white, it means that 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 power, or your power has increased!

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 too high degree, or your current degree is relatively light!

VII. Photometric adjustment:

After trying on the insert, get to know the customer's feeling of trying on it, ask if there is any distortion or confusion in vision, dizziness, dizziness and nausea, etc., and make appropriate adjustment and analysis according to the customer's feedback.

VIII. Prescription:

According to the customer's original glasses, make corresponding adjustments to eye needs, occupation, working environment and living habits, and then issue a prescription for glasses suitable for customers.
