If necessary, the frames to be fitted are checked to ensure they are appropriate for re-glazing (e.g. plastic frames are not brittle). The old lenses are then removed.
The shape of the frames is traced in a tracing machine.
New prescription lenses come in big round discs, like these ones - the thickness of the disc depends on the strength of the prescription.
An edging machine is used to grind the discs to the correct lens size and shape for the glasses frames.
The lenses are fitted into the glasses frames.
The new lenses are cleaned and polished and the glasses are ready for delivery.
