The Art of Making Premium Eyeglass Frames
Behind every exceptional pair of eyeglass frames lies a manufacturing process that is far more intricate than most wearers realise. Premium eyewear — particularly acetate and titanium frames — involves dozens of individual steps, skilled hands, and meticulous quality control at every stage. Understanding this process deepens appreciation for what you are wearing and why craftsmanship matters.

Step 1: Material Selection
Acetate Sheets
For acetate frames, the process begins with the selection of raw acetate sheets. Premium manufacturers source sheets with consistent thickness, rich pigmentation, and no internal bubbles or imperfections. The pattern and color of the sheet will determine the final appearance of the frame — a decision that requires both technical knowledge and aesthetic judgment.
Titanium and Metal Alloys
For metal frames, raw titanium or beta-titanium alloy is sourced in rod or sheet form. The purity and alloy composition directly affect the frame's weight, flexibility, and corrosion resistance. Premium metal frames use aerospace-grade materials for maximum performance. Browse our metal frames collection to see the results.
Step 2: Cutting and Shaping
Acetate sheets are fed into CNC (computer numerical control) milling machines that cut the frame front and temples to precise dimensions. Despite the use of machinery at this stage, the process requires skilled operators to monitor tolerances and ensure consistency. Metal frames are similarly cut and shaped using precision tooling, with wire-forming and stamping techniques used for finer components.
Step 3: Assembly
Hinge Integration
One of the most technically demanding stages is hinge integration. For acetate frames, metal hinges are embedded directly into the acetate using heat and pressure — a process that requires exact alignment to ensure smooth, long-lasting operation. The quality of this step is one of the clearest indicators of a frame's overall build quality.
Temple Attachment
Temples are attached and adjusted to ensure correct alignment with the frame front. At this stage, skilled craftspeople check that the frame sits level and that the temples open and close with the correct tension.
Step 4: Sanding and Refinement
Acetate frames go through multiple stages of sanding — from coarse to ultra-fine grits — to remove machining marks and refine the frame's edges and surfaces. This is largely done by hand, with craftspeople feeling for imperfections that machines cannot detect. Metal frames are similarly filed and smoothed to remove any sharp edges or surface irregularities.
Step 5: Tumble Polishing
Acetate frames are placed in large tumbling barrels with polishing compounds and wooden pegs. The frames tumble for many hours — sometimes over 24 hours — until they achieve the smooth, glass-like finish that premium acetate is known for. This process cannot be rushed; the duration directly affects the quality of the final polish.
Step 6: Lens Fitting and Quality Control
Once the frame is complete, lenses are fitted and the finished product undergoes rigorous quality control inspection. Dimensions are checked against specification, hinges are tested for tension and alignment, and the surface finish is examined under magnification for any remaining imperfections. Only frames that pass every check leave the production facility.
Why Handmade Eyewear Is Worth It
The handmade process is slower, more expensive, and more demanding than automated mass production — and that is precisely why it produces superior results. Each frame that passes through skilled hands carries with it a level of care and precision that machines alone cannot replicate. When you wear a premium handmade frame, you are wearing the result of genuine expertise.
