It can’t be done anymore.
Contact lenses are medical devices and require strict fitting before they can be worn, just like prescription drugs must be sold in hospitals but not in pharmacies.
In fact, many people buy based on their feelings, which in itself is a sign of irresponsibility for their bodies. Even if you go to an optical shop, they will help you measure the light and teach you how to wear it. Let me teach you about disinfection. Optical shops at least have industrial and commercial and qualification supervision, but online shops cannot guarantee this, and there are no requirements for "opticians" or eye examination equipment. Therefore, it is stipulated that such goods are not allowed to be sold online.
As a responsible attitude toward other people’s bodies, it is better to buy contact lenses in physical stores. Of course, there are also online stores that illegally sell contact lenses secretly. It depends on how you deal with it. In short, it is not a public practice, and it is definitely not recommended. .
I have also seen a lot of questions about contact lenses on the Internet. Except for the experienced, many novices know nothing at all, and they don’t even know how to wear them, but they think they know. Selling is certainly risky and difficult to regulate.
