What are the parts of the glasses?

The main elements are:
  • Circle or ring: part of the frame that surrounds (or blocks) the lens.
  • Edge or profile: the concave part where the lens is embedded.
  • Front: part of the frame that includes the two circles, the bridge (4), the nose pieces (7) and part of the hinges (10).

What is the spectacle frame?

Today there are an infinite number of frames on the market, each different, each unique, which differ in materials, shapes and sizes, colors and in the type of lens mounting.

What is the caliber for glasses?

The third number (in our example it is 145) indicates the length of the shaft, which holds the glasses firmly to the face by leaning against the ears.

How should eyeglasses fit?

If the root of the nose is wide, you have to opt for a wide and high bridge, otherwise the glasses will remain too high. It is good to choose a bridge size of 19 or 21mm. The glasses must fit in the upper part of the nose, in correspondence with the bony part and not at the bottom of the cartilage.

How to position the nose pads of the glasses?

If the glasses are too high, just widen the nose pads with the help of your fingers (the nose pads move easily), thus making them slide gently downwards. On the contrary, by tightening the nose pads, the glasses will rise in the upper part of the face.

How to bend the temples of the glasses?

How to straighten the stem of the glasses?

In case of intervention on plastic glasses, we should always heat the same area (intersection between the final part of the rod and the rim of the frame) with a hairdryer and bend gently as soon as you notice that the material is slightly warm and so ready for adjustment.
