Aviator Sunglasses: History, Design & Manufacturing

Why the Aviator Is Still Selling After 80 Years

The aviator started as a military procurement problem. In the early 1930s the US Army Air Corps asked for a sunglass that would protect pilots from glare at altitude without fogging or falling off, and the design that answered — a large teardrop lens, a thin metal frame, a double bridge for strength — entered service with Army pilots. Then the war ended and the frame did not. It came back in the 1960s as a civilian icon, exploded again in the 1980s on film posters, and has been a permanent fixture of every eyewear catalogue since.

For a factory, what matters is what that history does to your buying. The aviator is one of the longest-lived SKUs in eyewear: the geometry barely changes from decade to decade, which means a buyer is never gambling on a frame shape that will look dated next spring. The styling cycles through finishes and lens tints — gold with green G-15 lenses, then gunmetal, then blue mirror, then crystal tints — but the underlying metal frame stays the same SKU. That is why every serious frame factory keeps aviator tooling permanently installed. It is the closest thing eyewear has to a product with guaranteed demand.

It also means the market is flooded with imitations. The aviator is easy to copy badly: a cheap casting, a paint-like plate and a lens clipped in looks identical to a proper frame in a product photo. The difference shows up in your customer's hands, which is why the rest of this guide is about the structure, the materials and the QC — the parts that a photograph cannot show you.

The Design Specs That Define an Aviator

Before you can spec an aviator order, you need to know what makes a frame an aviator rather than just a big metal frame. The definition is structural, and every element of it is a manufacturing decision.

The teardrop lens. The lens is wider at the top and tapers toward the bottom — that shape follows the natural upward line of the cheekbone area and gave pilots maximum downward field of view for reading instruments. In production terms it means the lens blank has a pronounced difference between top and bottom width, which affects how the lens is edged and how much material is wasted. Standard sizes run 55 mm to 62 mm in lens width, with 55□14 and 58□14 the two volume sizes most factories keep in stock.

The one-piece top bar with double bridge. This is the signature element. The top of the frame is a single continuous piece of metal that forms the upper rim of both lenses and carries two bridge bars connecting to the nose. One-piece construction means the critical strength is in the metal itself, not in a joint, and the double bridge spreads the weight of two large lenses across the nose. In manufacturing, the top bar is either stamped as one piece or built from wire and welded — the first sign of a cheap aviator is a top bar that is visibly two halves joined in the middle.

The thin lower rim. Unlike a wayfarer, where the lens is fully wrapped in a thick frame, the aviator's lower rim is a thin wire that holds the lens from below. Some versions drop the lower rim entirely for a rimless look. The thinner the lower rim, the more the lens edge is exposed — which is why lens edge quality and lens thickness matter more on aviators than on any plastic frame.

The bayonet temple. The original military frames used a straight temple that passes over the ear without hooking behind it, so the glasses stayed on under a pilot's headset. Modern aviators come with both bayonet and the more common curved skull temples — worth knowing, because the bayonet version is a genuine selling point for drivers, cyclists and anyone who wears sunglasses over headphones, and most retail buyers have never been shown the difference.

The adjustable nose pads. Aviators carry two small pads on adjustable arms rather than a fixed plastic saddle bridge. That lets an optician or the wearer bend the pads to fit the nose — a feature that only works on metal frames, and another reason why cast-metal or plastic "aviators" are not really aviators at all.

How Metal Aviator Frames Are Actually Made

Every metal aviator on the market comes off one of three production lines, and the line decides the price floor. Once you can identify which one you are being quoted, most of the mystery disappears.

Route one: stamped sheet metal. The frame profile — the top bar, the lens rings and the bridge shape — is cut and formed from a flat sheet of metal using progressive stamping dies. This is the volume route: dies are expensive to make ($1,500–4,000 for a set) but cheap per piece at scale. The formed parts are joined at the hinge area and the bridge with solder, then polished, plated and assembled. This route produces the vast majority of mid-market aviators, and its quality ceiling is set entirely by how much hand-finishing the factory does after stamping — which is why two stamped frames can look identical in a catalogue and feel completely different in the hand.

Route two: wire-core construction. Instead of stamping the rim from sheet, the frame is built from drawn metal wire that is bent to the lens shape and laser-welded at the joints. Wire construction is how classic European aviators were made, and it allows thinner, lighter profiles than stamping. The welds must then be ground and polished flush — visible, sloppy welds at the bridge are the giveaway of a rushed wire frame. This route runs slightly more expensive than stamping and produces the frames that opticians describe as "feeling like a real aviator".

Route three: cast or machined premium builds. Some "aviators" are die-cast zinc alloy — cheap to produce in complex shapes, but brittle and prone to snapping at the hinge, and they cannot be adjusted. At the other end of the premium scale, titanium aviators are machined or formed from titanium sheet and joined with dedicated titanium welding under inert gas, which is a genuinely different skill set. If a supplier quotes you a titanium aviator at stainless prices, it is not titanium.

Whatever the route, the finishing line is where the quality is made or lost. Frames move through: mechanical polishing to remove tool marks, electroplating (a base layer plus the visible finish layer plus a protective top coat) or PVD coating on stainless and titanium, then assembly — hinges fitted and pinned, adjustable nose pads mounted, lenses edged and snapped or screwed in, temples attached. A proper factory salt-spray tests plated frames for 24–48 hours and cycle-tests hinges. A frame that skips any of those steps will save the factory a few cents and cost you your reorder rate.

Monel vs Stainless vs Titanium: What You Are Paying For

Ask ten suppliers what their aviator frames are made of and you will get variations on three answers: Monel, stainless steel and titanium. Here is what those words actually mean on a factory floor and in your unit cost.

Monel. A nickel-copper alloy, and the traditional aviator material. Its two properties matter to eyewear: it resists corrosion from sweat and salt air, and it is malleable enough that a frame can be adjusted to fit a face without breaking or losing its temper. Monel takes a bright nickel or gold plate exceptionally well. The cost sits roughly 30–50% above stainless, which is why it is the default for mid-market and premium retail aviators but disappears from rock-bottom quotes.

Stainless steel. The value workhorse. Cheaper, harder and perfectly adequate when the plating is done well — many of our stainless frames are PVD-coated rather than plated, which makes the finish dramatically more durable against peeling. The trade-offs: stainless is stiffer, so in-store adjustments are harder, and it is slightly heavier than Monel. For price-driven wholesale and promotional aviators, stainless is where the smart money goes — provided the factory's finishing line is good.

Titanium. Roughly 40% lighter than stainless, hypoallergenic, and almost immune to corrosion. It also costs more per gram, needs dedicated welding, and is harder to finish in bright mirror colours. A genuine titanium aviator runs $4.50–9.00 FOB — worth it for a premium line marketed on weight and skin comfort, unjustifiable for a $15 retail frame. And again: if the price says stainless, the metal is stainless.

The honest framing advice I give buyers is to pick the material that matches the retail price point you are aiming at, not the most impressive-sounding alloy. A well-finished stainless aviator at $2.50 FOB will outlive a badly finished Monel frame at $3.80 — the material matters less than the finishing, and the finishing is what you cannot see in a photo.

Buying Aviators Wholesale: MOQ, Pricing & QC

Here is how a metal aviator order actually comes together, with the numbers we work with every week.

MOQ tiers. On a stock aviator shape — our standard 55□14 and 58□14 — with your choice of finish, lens colour and a laser-engraved logo, the MOQ is 100–300 pieces per colourway, with 7–10 days of production after sample approval. If you want a custom frame geometry, your own colour plate or a die-cut bridge, expect 300–600 pieces per colour and 25–40 days, plus $1,500–4,000 in one-time die tooling. The die is yours to reuse on every future order, which is why a custom bridge becomes cheaper per order the longer you run the model.

Pricing by material, on a stock 58□14 with G-15-style tinted CR-39 lenses and a polybag. Stainless: $1.80–3.20 FOB. Monel: $2.50–4.50 FOB. Titanium: $4.50–9.00 FOB. Each upgrade stacks on top — polarized lenses add roughly $0.60–1.20, a branded hard case $0.50–1.00, PVD coating in place of galvanic plating $0.15–0.40. A "fully dressed" Monel aviator with polarized lenses and a branded case lands around $4–6 FOB, which is a very different product from the $1.20 quote that started this article.

Lenses on big frames. A 58 mm teardrop is a large, fairly flat lens, and the lens is half the product. We default to CR-39 for value, polycarbonate for impact resistance and nylon for thin, high-clarity builds, all with UV400. On a frame this wide, a cheap lens shows distortion at the edges within minutes of wear — inspect the lens, not just the frame, on your first sample.

The four QC checks to put in writing. One: solder and weld points are ground, polished and invisible to a fingernail. Two: left and right lens apertures match within 0.3 mm — lay the frame on a grid and check the opening symmetry. Three: the factory runs a 24–48 hour salt-spray test on plated frames and shows you the report. Four: hinges are cycle-tested (10,000 opens is the number we use) and the frame survives a gentle twist test without permanent distortion. Any factory that hesitates on these four has something to hide — the two most common metal-frame complaints, plating peeling and blackened joints, are both caught by checks two and three before a single pair ships.

The aviator has outsold almost every frame ever designed because its geometry never goes out of style. Buy it the same way — build a spec sheet that does not change with the fashion cycle, hold the factory to the QC list, and let the finishes rotate. That is the whole strategy.
