How are eyeglasses supposed to fit?
Eyeglasses are supposed to fit so that the arms, or temples, should go straight back from the frame and only touch at the wearer’s ear.

The bridge of the glasses should match the shape of the nose so as to rest gently on it. If there are nose pads, they should not be angled into the nose. The lenses should be far enough from the eyes so that eyelashes don’t touch.
