Wear method
Eyeglasses are often worn and removed, but the gestures to be worn are correct. Whether you wear or remove it, you should use the fingers of both hands to hold the temples close to the pile head and spread it to fit your head. When the width of the part is smoothly put on or removed, it is not possible to wear glasses with one hand, because wearing the glasses with one hand will cause uneven force on the right and left temples, and due to the moment effect, the temples will be easily broken. It is common right-handed wearing glasses that cause the left foot to break at the hinge; used to wear with the left hand, it will cause the right foot hinge to break.
