After glasses have been worn for a while, they may begin to sit crookedly on the wearer’s nose. This is not only unattractive; it can also be bad for the wearer’s vision. Damaged eye glasses will need a professional’s help, but it isn’t necessary to visit the optician’s office just to straighten glasses.
The temples may be bent out of shape, which could cause the frames to sit closer to the wearer’s face on just one side. It could also cause one side of the frame to be higher than the other. You can straighten the glasses by bending one or both temples slightly, especially where they rest on the wearer’s ears. Be sure to proceed very slowly, because it’s easy to break the temples.
The eye glasses may look crooked on the wearer when they are, in fact, perfectly straight. This happens when the frames have not been fitted correctly to the wearer’s face. Many, many people have one ear that is slightly higher than the other, or is placed slightly further back on the skull. These differences in placement are so small that they’re not even noticeable, but if the fit of the eye glasses is not adjusted to accommodate them, the glasses will look crooked. Bending the temples slightly will adapt the shape of the eye glass frame to the shape of the wearer’s skull.
