Glasses have become rather precise and to some degree skilled engineering tools in recent times. There are tightly calculated points of influence and balance in the primary axes that can either benefit you or counter to you!
The sequence of these points of realignment can make the glasses feel relaxed and relaxed on your face, but it requires all points to be worked together and in a choreographed sequence in order for the operation not to become “Rubik Cube” like.
The first thing to do is to establish that all points of connection are tight and securely connected – so check each screw to guarantee that it is firm. This will ensure that any further adjustments not only work correctly, but also remain place for a practical amount of time. The usual symptom of “having a screw loose” is that the sides of the body become wobbly and saggy on your face – so that is always a good place to start.
If the glasses are shifting down on your face, it is quite likely that the sides of the frame are not equal and one or both need some modification. Place the glasses face down on a white cloth or sheet and looking straight down at the glasses along the side frames, see if they are directly perpendicular and orthogonal to the front frame. If one or both are not then prepare to align.
All frames have some metal running down the axis of them, and it is this that demands to be twisted back into shape – that’s one of its functions! The trouble is that the metal is usually coated or surrounded n plastic or acetate that leans to chipping or parting when bent.
The best way to approach this predicament is to heat the sides of the frames with a hot air source – a domestic hairdryer works perfectly – and then rectify each side alternatively in small increments until they have gained the regularity of the frame.
In the case of metal frames, the glasses can be made to sit higher or lower on the face by adjusting the nosepads inwards or outwards. Again, take care and do each one alternatively and incrementally so that you can measure the result from each tweak and adjust accordingly. Plastic frames generally do not have nosepads.
If the glasses are sitting on your face comfortably, but are not straight or level on your face, it is likely that one side is bent up or down relative to the other side. To best remedy this, firmly grasp at the hinge – and then gently bend. Be careful however, as considerable force is sometimes required, and this is a natural weak point in spectacles, and so they can break here quite easily. Be firm with positive force rather than quick jerky movements.
