Do you need anti-slip stickers on both sides when processing glasses?

After the users of Xiaohongshu share the query, this only needs to be posted on the inside.

Anti-slip stickers for glasses processing should only be attached to the inside of the temples to improve the comfort and stability of wearing. As for whether the front and back sides of the anti-slip sticker need to be pasted, generally, only one side of the anti-slip sticker needs to be coated with glue, and then pasted at an appropriate position inside the temple. If it is posted outside, it doesn't mean much.

Therefore, in this case, the anti-slip sticker only needs to be attached to one side, and there is no positive or negative difference, only to the inside position. At the same time, when sticking the anti-slip sticker, make sure its position is appropriate, firm and reliable, so as not to cause inconvenience or danger to the wearer.
