There are many places where Xi installs glasses, which is not the most professional, but the glasses I went to lead last time were quite good, because their instruments and equipment, including the professionalism of the staff, were very powerful, and they told me very clearly, and I also told everyone who didn't know how to wear glasses very clearly and comfortably, so they could be said to be very good!
I feel that the environment is not bad. Friends from other places came to get glasses and gave me free postage. The policy is good.
