FAQ

The term is as old as the material itself. Early eyeglass frames — dating back to the 13th century — were made from what nature provided: wood, metal, leather, bone. And horn.
Animal horn was ideal: available, malleable, durable.

The name endured.

In the 20th century, horn-rimmed glasses experienced their great cultural heyday. In the 1920s, American comedian Harold Lloyd made the distinctive frame world-famous — as the trademark of his film character, the archetypal everyman. Later, horn-rimmed glasses became the face of politicians, lawyers, and intellectuals. They radiated seriousness, competence, and permanence.

Then came plastic. And with it, a subtle shift in meaning: Today, "horn-rimmed glasses" in common parlance usually refers to dark, heavy eyeglass frames made of acetate or other plastics — glasses that merely look like horn but are not.

At Bachoff, we carry the term with conviction — and with full justification. Our horn-rimmed glasses are made from genuine buffalo horn. No plastic in horn-like appearance, no imitation. But the original — exactly as the term has meant from the beginning.

Buffalo horn is one of the oldest craft materials in human history — and at the same time one of the most fascinating. It comes from the horns of the water buffalo, composed of keratin, the same protein that makes up human fingernails and hair. Yet what sounds abstract becomes an experience in your hand: buffalo horn feels warm, almost intimate. It is light, pleasant on the skin, and responds gently to body heat — it practically molds itself to you.

For eyeglass construction, it is nearly ideal. The material can be bent and adjusted with mild heat without cracking or breaking. It is lighter than most metals and more stable than many plastics. And then there is the visual aspect: no two pieces of horn are alike. Blonde, almost transparent sheets with a yellowish shimmer.
Deep, nearly black horn with a mysterious gleam. And in between, everything — flames, gradations, inclusions, patterns that no designer could have invented.

What sets buffalo horn apart from everything else: it was once alive. This quality is visibly embedded in it — and passes on to the eyeglasses made from it.

Our horn comes from Muradabad, a city in the northern Indian state of Uttar Pradesh, known for centuries for processing natural materials. We have worked with the same small family business there for over ten years — a manufactory that has passed down its craft through generations and whose understanding of quality matches our own. They supply us with the horn sheets from which we craft the eyeglasses here in our workshop.

The horn we process is the last valuable remnant of a complete utilization chain. The water buffalo is raised in India primarily as a dairy animal — buffalo milk is the foundation for countless food products and one of the country's most important agricultural resources. Meat and leather are also used. The horn comes at the end of this chain: it would be the only thing left over — and instead becomes something that lasts for decades. No animal is killed for its horn.

There are certainly other horns. Sheep, goat, yak — all natural materials, all keratin. But making an eyeglass frame requires very specific properties, and buffalo horn fulfills them like no other.

First, there is sheer size. Buffalo horns are large enough to cut a complete eyeglass frame from a single piece — without laminating, without assembly, without compromise. Sheep or goat horn is ruled out for this reason alone.

Then there is the internal structure: buffalo horn is homogeneous, stable, and yet elastic enough to be adjusted with mild heat. It can be milled and hand-worked without splintering or cracking — a material that works with the craftsman rather than against him.

And then there is the aesthetics. The color palette of buffalo horn is unique: from pure blonde, almost transparent horn to deep, nearly black material — and in between a world of flames, gradations, and patterns that no designer could invent. No other horn offers this variety in this quality.

Buffalo horn also has a centuries-long tradition in eyeglass manufacturing. It is not an experiment or a passing trend. It is the material that has proven itself over generations — and for good reason.

The difference begins the moment you pick up the eyeglasses. Buffalo horn feels warm. Plastic feels cold. This sounds trivial — but it is the first of many signs that you are dealing with a fundamentally different material.

Horn is light, sits pleasantly on the skin, and ages — but it ages honestly. It becomes duller; dark horn can lighten with minimal care. Those who see this as a flaw care for their eyeglasses. Those who love precisely this character — the matte, the slightly lightened, the worn — let it happen. Both are valid approaches. Plastic, on the other hand, ages less gracefully: most acetate eyeglass frames contain plasticizers — chemical compounds that give the material its flexibility. Over the years, these plasticizers evaporate, the eyeglasses become brittle, and in areas exposed to sweat and skin contact, a whitish coating forms — a telltale sign of decay that is difficult to remedy permanently. Buffalo horn does not have this problem. It contains no additives, no chemicals, nothing that could evaporate.

This is also medically relevant. Phthalates, the most common family of plasticizers, are now considered harmful to health — they are not firmly bound in the plastic and can enter the body through skin contact, sweat, and friction. Those with sensitive skin or prone to contact allergies often deliberately choose horn. It is a pure natural material, skin-friendly, chemical-free — and has long been recommended by dermatologists and allergists as a particularly skin-friendly alternative.

And finally: no plastic frame is unique. Every plastic eyeglass is one of thousands of identical copies. Every horn eyeglass is not, by nature.

Horn eyeglasses require care — but they are far less demanding than one might think. The most important rule: oil them regularly. At least once a month, and whenever the eyeglasses appear duller than usual — that is the material's signal that it is time.

Any pure oily or fatty substance that you would use on your own skin is suitable as a care product. Coconut oil, almond oil, vaseline, a drop of olive oil — all are excellent choices. Special horn care products are not necessary and are often simply overpriced. Apply the product, let it work overnight, and wipe away any excess the next morning. When applying, some care is required: the care product should only touch the horn, not the lenses.

Special attention is warranted during summer vacations at the seaside. UV radiation and salt-laden air cause the horn's surface to age noticeably faster — during this time, it is worth caring for it more frequently.

As for moisture: horn eyeglasses easily withstand a rain shower. Prolonged wetness, however, should be avoided. And while you can conveniently clean plastic eyeglasses under running water with a drop of dish soap — this is not advisable for horn. The lenses of buffalo horn eyeglasses are cleaned dry, with a microfiber cloth. A small difference in daily life that you will stop noticing as a limitation after a short time.

The honest answer first: as a raw material, buffalo horn is not particularly valuable. What determines its price is not the horn itself — but everything that comes after.

Already the production of the horn sheets from which we mill our eyeglasses is a labor-intensive craft process with many steps. And even then, nature has a say: not every sheet is flawless. Light horn is significantly rarer than dark — and correspondingly more expensive. For each eyeglass, we need two sheets: a thicker one for the bridge, a thinner one for the temples. But material cost ultimately plays a subordinate role in the final price.

The real cost factor is labor time — and it is enormous.

A plastic eyeglass can be manufactured automatically. Buffalo horn cannot. The material demands patience and a delicate touch. To thin it at the right places, you remove layer after layer — gently, carefully, without haste. After this process, many manufacturers use a grinding drum: it rounds the edges and makes the eyeglass parts smooth — quickly, evenly, mechanically. At Bachoff, we do this entirely by hand with many different abrasives. The CNC mill only handles the rough milling of the blank from the sheet — every subsequent step is handwork.

And then there is the risk that every horn eyeglass maker knows and must accept: you work for hours on a bridge or temples, it is almost finished — and then the material reveals a flaw that was not visible before. No undo, no quick fix. You start over. This moment is part of the craft. It explains why a horn eyeglass has its price — and why this price is higher than that of a plastic eyeglass.
