The eyeglass (1) has a frame part (3) provided with eyeglass lenses (5, 7) and holding mechanisms (9, 11) holding the eyeglass in a head of a wearer. A set of accommodation mechanisms (14a, 14b) detachably accommodates two side parts separately from each other for controlling a gap between the frame part and face of the wearer of eyeglass during the usage, where the frame part and the side parts are made of thermoplastic plastics. A bridge (15) is arranged between the eyeglass lenses, and is adapted to vision physiognomy of the wearer.
