Construction Parts (Drawings)
This is the frame of the glasses. It serves as the part that connects all the pieces together; the arms on the hinges on the back and the lens in the middle of the openings.

This here, is the right arm. It hooks up to frame by the hinges on the back of the frame and is held in place by a screw. This piece actually consists of two parts; the long, curved part and the part that connects to the frame. The arms allow the glasses to be held in place in the users ears.

This here is the right lens. It is exactly a mirror image of the left lens, as they both serve the same purpose and fit in relatively the same areas. This lens goes and is held in place by the gap in the frame. Pressure keeps the lens in place. The lens protect the user from exposure to (too much) light.
