"Yes, in the past, the flat (no degree) pupil is not a medical device, because there is no vision correction function, so some people in order to make money, they make fake, or cottage. You've been to the street plaid store, those places sell a lot of fake products, very unsafe, some people wear, eye problems, often reported in the news, so the FDA included it in the medical device, uh, this is just a short time ago. However, the new policy of the FDA mentioned in the "color contact lenses" is a large category of flat color lenses. The color contact lens is just a brand in this category, in fact, it is a registered trademark of Johnson & Johnson, which entered China earlier, I remember when I first started to wear it, and now I basically wear it. A lot of students around me are also wearing.
Now the regulation of such products is more and more strict, because the market has been on the market before some fake and shoddy color film, the state only set the policy, but Johnson pupils are certified, has been a trustworthy good east wow, I have been using it Oh, quite good!
