All over the world et al,
I am pleased to see this post as discussions on bespoke spectacles have been sparse, yet I hold the subject in the same light as bespoke tailoring and shoemaking, respectively. Indeed, the art of framemaking parallels the other bespoke arts: a dwindling supply of talent as the old move on; a once common trade relegated to a few hands sought after by the discerning few; diminished access to beautiful natural materials; really, any of the themes discussed here on the London Lounge.
Horn from various types of animals are available, much like skins for shoes, the most common being Indian water buffalo which is a by-product of agriculture. While skins go through the tanning process, the hollow horns are boiled in oil afterwhich blanks are planed and aged over several years to develop the required dimensional stability. When it comes time to make a frame, it is roughly cut out from the blank and then shaped by hand by grinding away material (sounds like last-making up to this point), bending with the application of heat and final polishing. Horn frames need to be moisturized with oil, and when done properly can last +20 years.
As to tortoiseshell, stock (i.e. blank) material is most rare, and my framemaker commented that any new tortoiseshell frame would likely be made from a pre-existing vinatge one. However one is obtained, it is more expensive and delicate than horn, and more beautiful too.
To bespeake or not? The craft, materials and process all speak to me - I am ill-placed to say nay. Concerns of changing eyesight are no different than fluctuating weight for tailored clothes. The simple alteration of prescription lenses are all that is needed, leaving the frame free to age with the wearer. Your main concern should be how the frames are made and if the process with the customer is truly bespoke. Know that horn frames may be fashioned out of a single solid piece of horn, or alternatively a laminate of various colored layers with inlays for added effect. I prefer the former, seeing it as a purer approach. Horn frames wear light and their depth of color is as emotional as any patina you would hold dear.
Below is a picture from early on in my bespoke frame journey. To the right are stock frames off which we were creating my sample frame (paper pattern). The frame is such a simple object, and yet each line, each curve and each corner was poured over, slept on and amended. Many sample frame iterations followed and I have been patiently waiting for delivery - a theme common to the bespoke arts!
Let me pose a question: have you considered a bespoke frame
wardrobe?
