According to Grand View Research, worldwide sales of small face female sunglasses will reach $7.4 billion in 2023, accounting for 31% of the global market for women’s sunglasses. Sales were accounted for by 58% Asian consumers. Women who have narrow faces require the frame width to be very strictly maintained to 50-53mm (55-60mm for the standard model), the height of the lens needs to be below 38mm, nose bracket spacing must match the specifications of the nose bridge at 14-16mm, and more than **± 0.8mm deviation will make 67% of the users have indentation problems. For example, Ray-Ban’s “Aviator Small” frame line with exact width of 51 mm **, titanium stems, weight of just 18 grams, and lens curvature radius optimized to 8 base bends (industry norm is 9 base bends), and sales have exceeded 250,000 pairs in the first half of 2024. The return rate is 32% lower than usual.
Material technology significantly improves comfort – Japanese company JINS ‘Air Ultralight’ series uses 0.3mm thick TR90 material, frame tensile strength of 110MPa, and the rear contact area increased by 40% to 90 square mm. Maximum pressure decreased from 12kPa to 6.5kPa. It is shown through a study conducted by the South Korean Seoul National University Biomechanics Laboratory that if the clamp force of the mirror leg stays between 0.4-0.6N, daily wear time can be up to 9.1 hours (6.3 hours for regular models). Market statistics confirmed that the customer complaint rate of silicone nose bracket models was reduced by 48%, such as Oakley’s “Micro Frame XS” nose brackets, which can be adjusted by 0.3mm, pushing this model to capture **22%** market share in Amazon’s small face category.
For women with small facial structures, optical compatibility is accomplished with an average pupillary center distance (PD) of 57 mm (62 mm in normal women) and the discrepancy of the lens’s optical center being less than **±0.4 mm **. French Essilor Group applying the “Nikon PrecisionFit” technology to reduce the lens eccentricity error to **±0.25 mm**, with 8.5 base bending aspherical design, view field distortion from 2.8% to 0.7%, UV blocking rate of 99.97%. China’s e-commerce site shows that the products’ price to consumers through this technology has increased by 65%, and LOHO brand’s “Air Lens Pro” series’ daily sales volume reaches 2,800 pairs with a re-purchase rate of 37%.
According to fashion trend, 72 percent of the trendy sunglasses for small face female are oval or cat eye type with vertical height 35-38 mm. The “Blondie Oval” collection that Gucci launched in 2024 has a 0.5mm metal wire along the top of the frame, the gradient of the lens to 0.06/mm, and the social media visibility more than 2.1 million times, impacting the brand’s 11% quarterly sales increase. Smart technology is built into a new highlight – Bose and Oliver Peoples’ “Frames Tempo Mini” features a gyroscope in the mirror leg to monitor the wearing tilt in real time (accuracy **±1°), and the total weight of the frame is 20 grams **. The speaker’s frequency response range is 100Hz-10kHz, and North America’s market share is now 9% in 2024.
Market feedback shows that the price of creating custom technology through 3D printing is reduced to **50/ pair ** (previous process ** 75/ pair **), and lead time is reduced from 20 days to 48 hours. Warby Parker’s “Virtual Fit” technology uses AI facial scanning (accuracy **± 0.5mm **) to increase fitting conversion by 31%, and its “Recycled Petite” collection uses recycled acetate fibers to reduce the frame carbon footprint by 45%. A 28% premium still achieves a 40% repurchase rate. Innovation in biodegradable products is also in the spotlight, with British fashion house Tom Davies’ “EcoPetite” rate of frame degradation of over 90% after 18 months in natural conditions, and 17% increase in sales in Europe in 2023, confirming the feasibility of sustainable development and accurate adjustment.
