oversized glasses frames are the fastest developing segment of the optics industry, with global sales 38.6% above year on year in 2023 and accounting for 27% of premium eyewear market (GfK statistics). Standard design parameters specify that the proportion of frames that are wider than 150mm has risen from 12% in 2020 to 41% in 2023, the lens height is more than 55mm (45mm average for standard models), and the contact area of the nose bracket is up to 52mm² (32mm² for standard models). Face pressure distribution is optimized to a maximum of 18kPa (32kPa for the standard model). Luxottica’s financial report indicates that its Ray-Ban Aviator Large Metal model, annual sales volume of 4.8 million pairs, frame width up to 154mm, 22% wider than the original model, nose frame uses 0.8mm titanium alloy thin-wall pipe (elastic modulus 110GPa), weight control to 24 grams (+3 grams reduction).
Material science advancements have created design innovations, such as from the conventional 3.5mm thickness of cellulose acetate sheets to 5.2mm (Mazzucchelli patented process), with a grain lamination precision of 0.03mm (tolerance ±0.005mm), and enhanced bending strength to resist 120N pressure (ISO 12870 standard demands ≥80N). According to Milan Eyewear Show 2024 data, Gentle Monster’s Myma series super-large mirror leg length was more than 160mm, suitable for 58-62cm people with head circumference (68% of global adults), the hinge system was upgraded to the third generation, and the life test of opening and closing was up to 15,000 times (the industry standard 5,000 times). The cost breakdown of the manufacturing process indicated that the board usage rate of the oversized frame reduced from 73% to 58% of the standard design, which raised the cost of production by 8.5 per pair but the retail premium value of 45,235 against $162 for the standard model).
Studies of consumer behavior show that 63% of Gen Z consumers define oversized frames as a digital selfie advantage (up to 85% face covered), and 12,000 new daily posts are published on the #BigFrameEnergy Instagram hashtag. Medication optometric observation reveals that 58mm frame width masks the edge aberration of high diopter lens (≥-6.00D) with a significant extent, and suppresses peripheral astigmatism by 42% (Zeiss Optical laboratory statistics). But ERGONOMIC problems remain: 29% of models subjected to the European Union 2023 ergonomic certification test experienced retroear pressure points over 35kPa (the 30kPa standard threshold), and the slip rate of the nasal support increased by 17% year-to-year.
Environmentally, 33% of large frame use is bio-based cellulose acetate (only 12% in 2022), with a carbon footprint 39% less than petro-based material. French brand Vuarnet launches the Eco-Large collection, the weight of the frame is reduced to 28 grams (15% less than the first version), using Marine plastic recycled material (recover rate certified by 93%). The trend for market differentiation is evident: Asian-Pacific consumers prefer 150-155mm broad frames (47%), and the rate of development of styles more than 160mm in the North American marketplace is 55% (assuming star street photography). Supply chain optimization data reveal that computerized injection molding cut down the production cycle from 18 days to 72 hours and enhanced the accuracy of the molds to ±0.01mm, but required an initial investment of $2.8 million/production line.
