It's been so many years!
　　When the dust falls on the glasses, I think the choice of most citizens is to take a breath to the glasses and take out the glasses cloth to wipe them.
　　However, a recent microblog said, "glasses cloth is not used to wipe glasses, otherwise it will cause lens wear; the function of glasses cloth is only used to wrap the lens, and glasses case isolated from ......"
　　Netizens exclaimed, "These years of glasses are white wipe?"
　　In response to the microblogging, Hefei bright opticians senior optometrist Chen Cheng said, the role of glasses cloth is indeed used to wrap the lens, to avoid its wear and tear with the case.
　　Chen Cheng explained that the previous lenses are optical glass lenses, have good resistance to wear and tear, can be wiped with glasses cloth. But now the vast majority of eyeglass lenses are resin lenses, wear resistance is poor. Eyeglass cloth is mostly given to consumers as a gift, so the cost is very low. It has a large fiber gap and will accumulate a lot of dust over time, so wiping glasses with such a cloth will cause the lenses to wear out and get blurrier the more you wipe.
