ABSTRACT:
A novel, improved ophthalmic device which comprises a unique fitting eyeglass frame having a removable nosepiece attachment which may be adjusted to permit adjustment of the lens to an exact eyelevel. The removable nosepiece attachment is pivotably connected to the ophthalmic frame, which allows a front-to-rear adjustment of the nosepiece on the ophthalmic frame, and the subject invention provides for a much improved pivotable connection between the nosepiece and the ophthalmic frame which may be rigidly locked in place by the novel use of a shim or friction member in combination with an extention of a female receptacle positioned in each side of the one piece nosepiece. Also disclosed is a device which is utilized for forming the removable nosepiece by forming a molded impression of a portion of a person's nose with the impression being used to then form the nosepiece for the person's eyeglass frames. The molded impression device comprises generally a mold for retaining a predetermined quantity of a molding substance along with a frame for retaining the mold and means for removably attaching the mold to the frame. There is also disclosed the mold for using with the molding device as well as the method for forming a molded impression with a molding substance of a portion of a person's nose for use in forming the removable nosepiece of the subject invention.
