Thus, the spectacle frame is not worn, and the spectacle frame and the face frame body 1 can interfere with each other.

Preferably, the first capsule 2 and/or the second capsule 5 are filled with gas and/or liquid in the cavity thereof, and the volume of the gas and/or liquid filled in the cavity of the first capsule 2 and/or the second capsule 5 at normal temperature and normal pressure is smaller than the maximum volume of the cavity thereof at normal temperature and normal pressure. For example, the maximum volume that can be filled inside the first capsule 2 means the volume of the first capsule 2 that can be filled with the maximum amount of water when the first capsule 2 is sealed at a temperature of 20 degrees celsius at a pressure of gas and/or liquid equal to one atmosphere inside the first capsule 2. When in use, the volume of the gas and/or liquid filled in the cavity of the first capsule 2 and/or the second capsule 5 under normal temperature and pressure is smaller than the maximum volume of the cavity which can be filled under normal temperature and pressure. This is the case when said first and/or second capsule 2, 5 are non-elastic sealed capsules, if elastic, the volume of gas inside said first and/or second capsule 2, 5 is not certain and can fill the whole of said first and/or second capsule 2, 5. That is, if the first and/or second capsules 2, 5 are elastic, the gas and/or liquid may be under-filled, and the amount of inflation gas and/or liquid may be selected from one third to one half, or may be over-filled, or even over-head, so that the pressure in the first and/or second capsules 2, 5 is greater than a standard atmospheric pressure.
