According to the 2023 “Optometry and face Matching Study” report, oval face (facial aspect ratio of about 1.5:1, cheekbone width of about 13-15 cm, chin Angle radius 8-10 mm) accounts for 34% of the world’s population, the suggested frame width of the sunglasses for oval face is 135-150 mm. Lens height 40-50 mm for face balancing. For example, Ray-Ban’s “Wayfarer Classic” style (lens width 142mm, lens height 45mm) optimized the facial proportions of 78% of users with oval faces in actual testing, its square shape enriched the angular feel, the stress of the mirror leg was evenly distributed (22% lower load load on the nose bridge), and the re-purchase rate on the Amazon platform was 29%.
In terms of material selection, the β titanium alloy frame (weight: 10-12 grams) is 50% lighter than traditional stainless steel (weight: 20-25 grams), the bending strength is as much as 800MPa, and the service life is more than 5 years. Oakley’s “Flak 2.0 XL” sports model possesses an O Matter™ material (elastic modulus 3.5GPa), a frame weight of merely 26 grams, and Unobtainium™ non-slip ear pads with a constant coefficient of friction of 0.35 at 80% humidity for outdoor use. According to 2022 North American market data, oval-faced users are 41% more likely to utilize this type of high-durability design than average users.
In lens technology, polarized lenses (transmittance 12%, UV blocking 99.9%) reduce glare interference by 70%, while gradient grey lenses (top transmittance 15%, bottom 65%) improve visual adaptation by 1.3 seconds under driving conditions. In Consumer Reports, 47% of oval face wearers regard light sensitivity fit as an important consideration in buying lenses. For example, Maui Jim’s “Ho ‘Okipa” series uses ColorBoost™ technology (color gamut coverage increased by 35%), lens curvature base curvature 8.25, fit eye curvature, reduce edge distortion by 18%, and sales increased by 27% year-on-year in the first half of 2023.
In terms of design strategy, geometric shapes (such as hexagons or pilots) can shatter the symmetry of the oval face and strengthen the sense of fashion. Gucci’s “Interlocking G” line (the upper part of the frame is 148 mm in width, and the lower part is narrowed to 132 mm), through the asymmetrical decoration of metal, the visual center is shifted upward by 12%, taking up 23% of the high-end eyewear market. The data shows that dark frames (such as matte black and charcoal grey) account for 58%, as they can shorten the facial visual length by 5%-8%, and the decorative rivets (diameter 2-3 mm) on the mirror legs can increase sunglasses’ width perception by 10%.
Market data shows that 61% of consumers virtually try on sunglasses for oval face through virtual try-on apps (e.g., Warby Parker’s APP), AI algorithms using 34 facial key points (e.g., cheekbone distance, jawline curve) with 91% matching accuracy, return rate dropped to 6.5%. That is less than the industry average of 11%. Additionally, the custom mirror nose bracket (4-8 mm height range of adjustment) improves an adaptation rate of up to 89%, for example, Persol’s “PO0719” model uses a patented hinge system to allow 15 degree adaptive bending of the mirror leg, and has recorded more than 80,000 pieces of sales in the Italian market within three months from launch, with customer satisfaction of 4.7/5.
