2. Placement method of optical glasses:

If the glasses are temporarily placed, please put the convex side of the glasses up; If the glasses are placed for a long time, please wrap the glasses with cloth and put them into the glasses case. Put the glasses case on the ear and shake it gently to distinguish whether the glasses are compressed by the glasses case.
