In fact, a lot of people go to buy their own sense, which itself is not responsible for their own physical performance, even if you go to the optical store, they will also help you to measure the light, but also to teach you to wear, to teach you to disinfect, the optical store at least there are industrial and commercial and qualification supervision, but the online store can not be guaranteed, and there is no "optometrists," the eye test equipment and other requirements, so the provisions of such goods, such as contact lenses, are not allowed to sell. The company's website is a good place to find out more about the latest trends and developments in the optical industry," he said.
As a responsible attitude towards other people's bodies, contact lenses are still a good idea, but of course, there are online stores that violate the law and secretly sell them, depending on how you deal with it, but in any case, it's a practice that can't be seen in the light of day, and it's definitely not recommended.
I also saw a lot of questions about contact lenses online, in addition to the experienced, many newbies simply do not know, and even with how many degrees do not know, but they think they know, online sales are certainly risky, but also very difficult to regulate.
