Eyeglasses frame calibration

The straightening.

This field is quite large and to cover in depth should refer to all kinds of frames (metal, pastinoi, griff, nylor, special occasions such pinfeel, wood, metal nylor etc.) together forever with their shapes, types of lenses (glass, organic, polycarbonate, trivex), the refractive index and the diopters. We will briefly try to refer to general rules and procedural controls needed during the straightening process of a skeleton.

1) Required tools

  • Heater
  • arm adjusting pliers, thin - 2 plastic
  • setting plier arm, coarse - 2 plastic •
  • Press brakes
  • Pliers arm tilt adjustment, plastic-metal

    2) General checks

    • Frame Control (material condition)
    • Lens Control (material situation) always inform the customer of this and the likely damage to fatigued points

      3) Identification of skewed point.

      • Check the correct application and the size of the lens. It is essential before embarking on any further action to make sure that the lenses are properly installed and the frame is screwed tight.
      • Check the front of the panel
      • • Check the riser top (look to have the same curvature and slope the shoulders
      • Check the riser underneath (the slope of the lens is the same)
      • • Control arm opening (back to the parallel position)
      • Control arm inclination (mounting frame upside down on the counter
      • Check akrovrachionion (straight frame positioning on the bench •
      • Check inclination of the arms in the closed position. (Be careful not to touch the akrovrachionia the lenses, especially in sun glasses)
      • Position control of epirinion.

        4) Straightening

        • Once you have identified where you want to straighten, remove preferably the lenses to avoid possible damage. The series of steps we take to straighten the frame is the same as the control range as described above.
        • The Isiomata of the panel made primarily from the bridge of the frame and sometimes only with hands. The basic rule is to keep the frame in such a way as not to accept the lens pressure and isolate the point we want to straighten keeping as close as possible to it. Avoid creating "lever" grasping the frame away from where we want to straighten. .
        • In Isiomata arm very useful tool is the arm tilt adjustment pliers. Particular attention should be given to the way you hold the frame with pliers in order not to "injure" the metal of the part. Also if the lenses are mounted, beware the power we exert to avoid a very common injury, the temporal alder. All the skeletons, pastinoi and metal, when they are old they want more attention. Their hand pastinous should always heat them thoroughly to avoid cracks or breaks (typical case breaking the old akrovrachionia), in particular metal apply the least possible pressure, not to peel off.
