The path of these glasses to our workshop began with a loose and lost screw that held the lens. When they were brought in for repair, we decided to completely restore their appearance. In the photo, Mont Blanc glasses with a lost screw, and as a result, a fallen out lens and a request to do “everything possible”.
Mont Blanc MB 77, color H58.
Overview.
The frame itself is made of silver metal, has silicone movable nose pads on studs and thin temples made of acetate. This is a combined classic design with a lot of work put into its details.
We anticipate a spectacular result after cleaning.
The surface of the frame on the sides where the lens was installed is abundantly covered with stains.
Branded toe caps with the snowy peak of Mount Mont Blanc.
And here is the main reason to visit the workshop – a lost eyepiece locking screw. At the same time, discolored areas of acetate are clearly visible in the frame. These white spots are the result of prolonged contact between the frame and the skin, where there is inevitably a lot of sweat.
The subtle geometry of the brackets hides their worn condition from a distance, but not from macro.
Wear and tear has not spared the area where the frame information is printed.
Digitally applied inscriptions on brackets will inevitably be erased during polishing.
Experimenting with the possibility of preserving this information during polishing, we tried using masking tape. But in this case, the plate appears with an untreated area, and in the end, the inscriptions themselves sometimes came off along with the tape. We came to the conclusion that it would be more expedient not to polish and erase digital printing in favor of a neat overall look. Of course, this decision is up to the owner of the frame. Inscriptions made by stamping with paint can be preserved and restored.
After a general inspection, the glasses were disassembled down to the nuts and bolts and immersed in an ultrasonic bath.
Taking care of the future assembly of glasses can save time, so every part is packaged and labeled after cleaning.
Sometimes the lenses themselves need to be marked. For example, to fit rounded lenses into the frame in the same position as they were in, horizontal stripes are first drawn on them with a ruler. This is because a diopter lens may have a degree of rotation that needs to be maintained. The marking looks like this:
Result.
The acetate stems were mechanically polished: first on a roughing cotton wheel to get rid of deep scratches, and then on a finishing woolen wheel to shine. The elements of the shackles, covered with dark blue enamel, were polished only on the finishing wheel so as not to damage the paint. We demonstrated the restoration process in the post“Polishing an acetate frame“.
The paste and the polishing wheel do their job.
The yellowed silicone nosepads were dismantled and replaced with new ones.
New Breitfeld & Schliekert toe caps.
The metal surface was not covered with rust, and the stains were just ingrained dirt, so the chrome plating layer remained intact. To make this thin coating shine and eliminate microscratches, we use mechanical polishing with a glossy finishing paste.
Restored metal surface.
Here is the bracket where the inscriptions were once printed.
Now it has a uniform glossy surface.
The effective means used to remove scratches on the surface of the frame cannot be applied to lenses. Because a) they have an ultra-thin layer of coatings on their surface, and b) the transparency of the lens would be damaged. Therefore, their participation in the restoration consisted of wet cleaning of the ends after dismantling.

A pair of glasses that had decomposed into all its individual parts was disassembled with a set of screwdrivers for an optical workshop by the German company Breitfeld & Schliekert, which looks like this:
