The accuracy rate of prescription data acquisition reaches 99.2%. Paper optometry reports within the last six months (including PD interpupillary distance and spherical/cylindrical lens diopter) are uploaded through the AI optometry tool, and the system’s recognition error is controlled within ±0.05D. The 2024 American Optometry Association report shows that the combination of online platforms and remote optometrists for review (with a response time of less than 15 minutes) has reduced the prescription error rate to 0.3%, which is 75% lower than manual entry in physical stores. Typical case: A South Korean user uploaded a -4.25D myopia prescription, and the AI automatically generated precise parameters of 92°±1° for the astigmatism axis, saving 45 minutes of in-store confirmation time.
The technical parameters of the lens are transparent, reducing costs by 37%. The median price of the 1.67 high refractive index lens is 298 yuan, saving 62% compared to 780 yuan in physical stores. Moreover, the Abbe number reaches 32±0.4 (the national standard requires >31). The anti-blue light substrate provided by Tokai Chemical of Japan has a filtering efficiency of 97.5% in the 415nm band and maintains a light transmittance of 92.3%. User tests have shown that the channel optimization of the custom progressive multifocal lens (ADD+2.00) has shortened the adaptation period from 23 days to 8 days. When choosing buy prescription glasses online, confirm the laser anti-counterfeiting code of the lens packaging (such as Hoya LX123), and the refractive index accuracy of the traceable material is ±0.001.
The virtual try-on system has a matching accuracy of 93%, and the 3D facial scanning technology has a recognition deviation of only ±0.3mm for the height of the nose bridge (within the range of 8-22mm). After a user uploads a selfie (with a pixel count greater than 12 million), the system generates 20 recommended frames within 11 seconds, with an eye height positioning error of ±0.7mm. The 2023 MIT Technology Review shows that this technology has achieved a frame width (134-150mm) fit rate of 98%, and the user return rate has been reduced from 12.4% to 3.1%. Key operation: When shooting head-on in natural light, the error of pupil distance can be compressed to 1%.
The payment and delivery efficiency is three times higher than that of physical stores. The proportion of 48-hour customization using a flexible supply chain is 83%. The median order fulfillment time in the Beijing-Tianjin-Hebei region is 56 hours (including lens grinding). The Zeiss Zhirui series lenses from Germany offer DHL global logistics tracking. The automation of customs declaration has reduced the customs clearance time for cross-border orders to 7 hours. The 2024 user report indicates that online payment integrates Alipay’s “Vision Health Insurance”, automatically compensating 15% of the order amount (up to a maximum of 200 yuan) if the order is delayed for more than 72 hours.
The after-sales system eliminates 98% of dispute risks. The 14-day no-reason return and exchange trigger rate is only 4.7% (2.1% in physical stores). Due to the pressure distribution sensing packaging (recording transportation jolts >5G acceleration), the efficiency of responsibility determination has increased by 85%. Essilor’s diamond crystal film layer from France comes with a 24-month warranty, and the median compensation period after the film crack warranty is triggered is 3.7 days. Historical data: The free redo service for frame weld point breakage (with a probability of 0.05%) saves users an average of 247 yuan in factory return costs.
Empirical cases have verified the reliability of the entire process. Mr. Zhang, a programmer from Shanghai, customized a 6.50D high myopia lens (PD 63.5mm) online. The actual measurement showed that the deviation of the pupil height was 0.4mm, saving 420 yuan compared to physical stores and having zero adaptation time. The key points of operation: Use the bank’s U-shield to confirm the SSL certificate of the payment page (encryption strength 256-bit), choose SF Express for valuation (valuation fee 0.8%) for logistics, and after the goods arrive, scan the QR code on the lens through the APP to verify that the refractive index is 1.67±0.001.
