Abstract
A method of making an eyewear frame having substantially rigid sections joined with a soft and/or flexible nose bridge. The substantially rigid sections and soft and/or flexible nose bridge are made in separate molding processes. The cured substantially rigid sections and cured soft and/or flexible nose bridge are then joined together in a further molding process by injecting a bonding material into interfaces between the soft and/or flexible nose bridge and the respective substantially rigid sections. The eyewear frame may be painted. A pre-painting surface treatment may be applied to the soft and/or flexible nose bridge before it is joined with the substantially rigid right and left sections.
