How to buy glasses online

Why buy glasses online? Because this can eliminate over 80% of excessive profits, I won't say much about the excessive profits of eyewear stores. They can be opened in the best store storefronts in downtown areas, and without sufficient profits, how can they be supported? Generally speaking, a profit of over 90% should be considered small. So we choose to buy glasses online because it's cheap. There are several steps to buying glasses online.

Usually, matching glasses involves four steps: optometry, lens selection, frame selection, and glasses processing.

Method 1: Offline optometry, online purchase, processing, and receiving of finished products

Moreover, simply buying glasses online is a prerequisite. You need to first undergo offline optometry and confirm the accuracy several times to see if you can go online to get glasses. So it's a combination of online and offline methods.

Method 2: Send out the old glasses, purchase and process them online, and receive the finished products

Another tacky way is to send the glasses you have worn before, which you think are suitable, to the glasses factory. They will test you for correct optometry data based on the parameters of your current glasses. This is still not as rigorous, and there may be errors.

Method 3: Buy lens frames online, perform optometry offline, purchase lenses, and process to obtain finished products

Generally speaking, the most profitable part of glasses is the frame. A regular titanium frame can be several hundred or thousands larger when viewed in a glasses store. We can purchase the frame online, which saves the cost and allows for significant discounts.

Where can I go offline for optometry?

For offline optometry, the first choice is to go to the ophthalmology department of a local hospital, or if conditions permit, go to a public specialized ophthalmology hospital for a few tens of yuan. The disadvantage is queuing up (public hospitals usually have dilated pupils for optometry, while regular adult optometry is usually sufficient). After optometry, obtain professional data from ophthalmology and then search for relevant lenses online.

Nonhospital optometry is also possible, but most optometry is still done at the eyewear store. Once they know that you are not buying it, but only optometry, they usually do not provide you with the data after the optometry, so just remembering the degree they said is not enough. Or there may be a certain cost to obtain this final optometry form.

Generally speaking, optometry is the biggest problem. When you go to an optician's store for optometry, the merchant understands that you will wear glasses online and not consume them in the store. Although optometry costs money, the merchant should give you good optometry. If it's not good, it will only harm your own eyes. It's best to wear glasses in the store for optometry, but you can choose the cheapest price, remember the optometry data, and choose a better one when there are online activities in the future.
