It is revealed in the 2023 Global Eyewear Market Research Report that heart-shaped faces (forehead width between 14-16 cm, cheekbone distance 12-14 cm, chin Angle between 50-60 degrees) constitute approximately 18% of the global adult population. It is appropriate for the glasses for heart shaped face to have a width of more than 140 mm and a height of 35-45 mm to balance the facial proportion. For example, Warby Parker’s “Percey” series of oval-shaped frames (148 mm wide, 18 mm nose bridge) were highly rated by 72% of heart-shaped face users in the consumer survey because the curved bottom design can soften the chin line, and the mirror leg is 145 mm long to stabilize and reduce the incidence of slipping by 30%.
In material, the titanium alloy frame (8-12 grams in weight) is 40% lighter than the common alloy (15-20 grams), and the elastic hinge (life of opening and closing of over 20,000 times) is able to decrease the pressure of the nose bridge (approximately 3.2kPa). Research within the industry has discovered that frames with acetate gradient coloring, such as those of Moscot’s “Lemtosh” amber, can optically narrow the forehead by 10 to 15 percent, and illuminate the cheekbone area by 20 lumens through the application of a 60 percent gradient layer top to bottom of light, and sales of these design types will be 37 percent higher in 2022.
The shape of the frame is a significant factor in the impact: Round or cat eye frames (with the upper edge angled 5-8 degrees upwards) can divert attention from the chin to the eyes. As stated in the Journal of Optometry experiment, while wearing a 142-mm wide circular frame, observers’ awareness of the sharp Angle of the chin dropped 23% whereas rectangular frames made cheekbones widening more likely by 18%. Ray-Ban’s “Erika” cat-eye model, for example, features a 134mm frame width and 12-degree upturn Angle and has a 4.8 star Amazon rating and 41% repeat purchase rate.
In terms of color strategy, cool tone (e.g., gun gray, navy blue) frames can minimize forehead vision by 5%-8%, and metallic rose gold legs (85% reflectivity) can maximize facial depth. According to market data, customers who have heart-shaped faces are 29% more likely to shop for a half-frame design rather than a full-frame design, as the lack of a frame at the chin can create a 15% less dense appearance in the chin area. JINS “\” Airframe “half-frame model of the series (weight 9 grams) uses 0.5mm super-thin titanium wire, nose bracket distance fits 90% Asian facial structure, and spring and summer 2023 sales increased by 53% year-on-year in the same period last year.
In consumer preferences, 61% of consumers prioritized frame size specifications: 6-8mm nose bracket height to avoid lens contact with eyelashes (45% less likely to occur), leg bend 120-130 degrees to align with the Angle of the ear. As an example, Gentle Monster’s “Lang” series, which adjusts the mirror leg torque value (0.8-1.2N·m) to provide a tailored fit, reported sales of 120,000 heart-shaped face fittings in the Korean market in three months, and the return rate was only 3.2%, well under the 9.7% industry average. The use of virtual tryon technology at purchase, like Specsavers’ AI solution, enhances the accuracy of matching to 89% and lowers trial-and-error costs by approximately 35%.
