Why buy glasses online? So we choose to buy eyeglass online for the sake of affordability. Usually, buying glasses online involves optometry, lens selection, frame selection, and glasses processing steps.

 

Offline optometry, online purchase, processing, and receipt of finished products. Moreover, there are prerequisites for simply buying glasses online. You need to first have offline optometry and confirm the accuracy several times before going online to get your glasses matched. So it's a combination of online and offline methods. Some also send out old glasses online, purchase, process, and receive finished products.

 

Another simple way is to send the glasses you have previously worn that you think are suitable to the glasses factory, and they will test the correct optometry data for you based on the parameters of your current glasses.

 

You can also buy eyeglasses online with cheap frames, undergo optometry offline, purchase lenses, and process them to obtain finished products. Generally speaking, the most profitable part of glasses is the frame. We can buy frames online to get significant discounts.

 

After offline optometry, obtain professional ophthalmic data and then search for relevant lenses online. Optometry mainly tests key data such as myopia degree, astigmatism degree, direction, and pupillary distance.

 

At present, most of the optometry is done by computer, and the results are more accurate. Nowadays, optometry is based on the degree of computer optometry and the distance between the pupils, which are key data. These data make it possible to match glasses lenses with very accurate prescriptions.

 

It should be noted that computer optometry will measure multiple times, and numerous sets of data are on the optometry sheet. Reference Data provides a shortened version of the data you are referring to. Computer data is only a reference and cannot be used as a basis for lens fitting.
