With glasses, the complete optometry process should pay attention to these details! Help you do your job better!

Embody professional words and behaviors: Just like the left and right hands, the left and right eyes will also have a dominant eye, and what it sees will be preferentially accepted by the brain. You are given haze to relax your eyes so you can measure accurately afterwards. Look at green first, then red and then green, and compare them to see if there is any clearer side. The eyes are balanced, and the closer the clarity is, the more comfortable it will be to wear. Ask customers not to squint their eyes to test, and if they feel tired, take a break before testing. Myopia can only be prevented, not treated. Things to improve the accuracy of optometry: Be sure to test the degree of the old mirror to compare it with the degree you measured at the end. If the old prescription has astigmatism, the new prescription should also have it. Even without astigmatism, you can see the same clearly. Ask about the needs of glasses. Some people need special lenses that can see clearly. If you have astigmatism, you need to add astigmatism to him. If the degree of spherical lens is increased to 1.2, you can increase the degree of spherical lens for him. After measuring the degree, be sure to try it on, let the customer walk around, and simulate the eye scene he needs to determine whether it is really suitable. Optometry, the red and green tones are always clear on one side, and finally the red side is clear. When red and green, you can ask the customer if the reading is crooked. If it is crooked, it means that the astigmatism is overturned. The binocular vision is balanced. If it cannot be balanced, the dominant eye must be maintained. If the visual target exceeds 0.7, the customer should read it out and point to it. The higher the degree, the smaller the adjustment range, and the visual acuity will not have a particularly big change, above -8.00. The method to improve the optometry efficiency: If the computer optometry is printed, the astigmatism is very small, so basically there is no need to check it for astigmatism. Just at the end of the best vision, ask if adding a little astigmatism has a significant improvement in clarity to make the final decision. The astigmatism axis printed by the computer is generally very accurate. If the old glasses have been worn for a long time, and the wearing is comfortable and clear, you can use the old glasses directly, and you only need to try them on. Ways to reduce after-sales: Inform customers that a one-week adaptation period is required to wear prescription lenses for the first time. Inform customers that if they wear astigmatism lenses for the first time, they may feel uncomfortable at first. Pregnant women, new glasses, will have discomfort, because pregnancy is sensitive, the lenses are brighter and clearer, which will cause discomfort. The correction of myopia is the minimum degree of optimal vision. Correction of farsightedness is the minimum degree of optimal vision. A few notes: Ask a doctor. You can ask him how long he has been wearing a pair of glasses recently, and learn about the replacement cycle. Just focus on relative vision improvement, even if 0.6 to 0.8 is good. When measuring astigmatism, the first addition must be 50. Audition and try-on principle: The principle is to place the lens at the most eye-friendly position with the smallest effective diopter. The principle is: the light transmittance of the tried-on lens is low, especially when the two lenses are stacked together. Test lenses have standard errors in optical diopter. The higher the degree, the greater the error. When there are two lenses, the closer the diopter is, the greater the error rate, so the maximum + minimum is required. Application: When the original wearing glasses do not have nose pads, the innermost A-slot needs to be used, and vice versa. Generally, the cylindrical lens is placed inside, but the spherical lens must be placed in the A slot. If the combined luminosity does not exceed 4D, the A slot can be used or not. It should be noted that if the spherical mirror exceeds 600, it will take 50 hops, the cylindrical mirror will exceed 300, and it will also be 50 hops, and if it exceeds 400, it will take 100 hops. Why not choose computer optometry: 1. The tested person is in an absolutely static state (that is, assuming the best state), which is impossible for ordinary people to do. 2. The operation process is completed in an instant, which is easy to cause tension and increase the degree of vision. 3. The average value of multiple measurements is actually not accurate.
