When you source blue light blocking glasses from factories overseas, there are many factors to consider. Qualification is one of the key factors. But how to identify whether they are qualified or not? The most straightforward way is by checking their certificates. In China, a qualified exporting factory should at least have a production license, and import and export certificate. Checking the qualification of a factory first is crucial. Otherwise, you may get the poor quality or due to the exporting restriction, you even can not receive the products, costing your time and money.
