Is the machine optometry sheet accurate?
With the rise of online shopping now, some people go to buy lenses online, but because glasses belong to "optical medicines", there is a shortage of prescriptions. In order to make a deal, some online sellers will match glasses with the optometry of the customer's machine, which is very harmful. Not only does the machine-made optometry sheet fail to reflect the true optical power of the customer, it may sometimes be wrong.
The worst phenomenon in the industry now is that once the customer is uncomfortable, let the customer wear it for a few weeks to adapt. Regardless of whether it is online or physical, it is very irresponsible to call you to adapt without checking the problem, excluding the optometry factor, the assembly qualification factor, and the frame adjustment factor. The human eye has a high error tolerance rate. The tolerance and flexibility of the human eye is also very large, and may adapt to adapt to the wrong glasses parameters. So next time if your glasses are uncomfortable, it should be the first time to review the optometry and processing parameters, and then adjust to the adaptation after no problem. Moreover, it should not exceed two weeks. If it is still uncomfortable after two weeks, consider optometry or processing errors. At this time, we must boldly propose to change the frames and lenses. No matter how professional and consummate the business says, don't believe it anymore and don't adapt. Re-optometry, re-processing and re-selecting the frame, your problem will be solved quickly. How high is the fault tolerance rate of the human eye? I have even seen that the left and right eye degrees have been reversed. Did the business fail to check it out or ask customers to adapt to reduce their own losses. As a result, it took two years to adapt. It was not discovered until the glasses were broken and replaced. I have seen the interpupillary distance unqualified many times, but the customer can't find it again. Let the customer go back and adapt. The more you adapt, you really feel better, and you really adapt. Adaptation has become the biggest excuse for imprecise fitting. Therefore, if you want to match glasses online, you must have very careful optometry data. Machine-printed data cannot be used with glasses.
Think about it for yourself, there are many parameters of online glasses that can't be measured, and the frame parameters are not easy to grasp. If you don't verify the basic parameters accurately, you can only adapt when you do it. If you are matching glasses online, in order to reduce the adaptation caused by this error, please be sure to find an optics mechanism that can provide accuracy and interpupillary distance. If it is a physical optician, once you find that you need to adapt for a long time, go back to the store as soon as possible. Don't force yourself to adapt to uncomfortable glasses, you should boldly propose to refit them. Think about it, and think about it, how many times have your opticians been called to adapt to by the business.
