Highlight 1: Wonderful speeches by authoritative experts in optometry
Practice and Prospect of Optometry Standardization in China
Ye Jiayi
Director of the National Optical Standardization Center
Secretary-General of the National Ophthalmic Optics Standardization Sub-Technical Committee
Director Ye Jiayi first introduced the structure and main achievements of the optometry standardization organization, and made a clear combing of the specific situation of the practice of optometry standardization in recent years, especially emphasizing that the group standards and fitting processes for microstructured spectacle lenses and eyeglasses led by the testing laboratory of Donghua University (National Glasses Enamel Quality Inspection Center) since 2019 have filled the gaps in standards and technical documents in this field at home and abroad. She pointed out that standards should be closely integrated with industrial needs to continuously meet the needs of development; advanced standards can drive the quality improvement of the entire industrial chain, optimize the industrial structure, and improve the added value of products and services; perfect inspection and testing can reduce quality information asymmetry, promote enterprises to improve product quality and management, and promote consumption upgrading; standards are a platform for technology accumulation and innovation diffusion, and she expects to cooperate with Naidejia in the future to explore, do a good job in the relevant standards of the television myopia prevention and control industry, and promote the high-quality development of the industry.
The Past and Present of Telegraphic Optical Reading and Writing Technology
Wang Tengyi
Executive Director of the Children's Clarity Program of the China Children and Teenagers' Fund
In recent years, myopia has shown a higher prevalence trend and a lower age of onset, which has attracted great attention from related research. Eye diseases such as retinal detachment, macular hemorrhage, choroidal atrophy and other eye diseases caused by high myopia constantly remind us that the core of myopia prevention and control in children and adolescents is to delay the growth of myopia. In this environment, far-image myopia prevention and control equipment has received extensive attention as one of the effective means of myopia prevention and control. In this regard, Director Wang Tengyi pointed out that unlike traditional close-up reading, the far-image myopia prevention and control equipment can pull the near object up to 3 meters away to form an upright and magnified clear image of the object, and at the same time has a high light intensity in the process of eye use. In conclusion, compared with traditional near-vision work, far-image myopia prevention and control equipment provides a new reading and writing mode, which is beneficial to the accommodative function and choroidal response of myopic children.
Optical Research on Myopia Defocus Mechanism and Protection Strategy
Wang Qiwei
Chief Technology Officer of Nadejia
Dr. Wang Qiwei pointed out that the development mechanism of myopia is complex, which is related to various factors such as axial length, corneal curvature and choroidal thickness. The center of the retina of the myopic eye is myopic defocused, while the periphery is hyperopic defocused, especially the peripheral hyperopia defocus has become one of the main reasons for the increase of myopia power. Experiments have proved that optical defocus exists, and the axial length can be quickly adjusted to obtain clear images, among which the OK lens can slow down the growth of the eye axis by reshaping the cell distribution in the central area of the cornea, forming a unique tire-shaped structure, and multi-point defocus lenses and microlens lenses can also alleviate the growth of the eye through point defocus and competitive defocus. As a comprehensive program of behavioral intervention and optical intervention, tele-image display technology is an intervention method realized by optical devices, which can be based on AR free-form optical technology, without changing the physical distance, to transform children and adolescents into long-term near vision without changing the physical distance, to achieve small space, long distance, large image effect, to solve the problem of visual fatigue and myopia caused by long-term close eye use, and to change the axial length and choroidal parameters.
Highlight 2: Telegraphic optical intervention, new technology for myopia prevention and control
01Technical advantages
Naidejia has independent intellectual property rights of freeform underlying optical core technology, and its first invention in 2019 patent "digital screen projection remote magnification reader" was approved by the State Intellectual Property Office. There are more than 200 patents in the field of optical technology, including 32 patents for tele-image optical technology.
Myopia defocus protection: seeing near becomes far, and the retina is naturally imaged, realizing myopia defocus protection from the main field of view and peripheral field of the retina, and then releasing the pressure of the sclera, and the choroid of the posterior pole is relatively thickened, effectively preventing the occurrence and development of myopia.
Optical display: The first industry-leading new technology for the prevention and control of far-image myopia with full immersion, zero stray light, and retina-level imaging. Retinal level imaging, angular resolution PPD is greater than 60, virtual image is flat without distortion and no depression, distortion parameter is less than 2%, and virtual image flatness is less than 0.05D.
Soft eye protection with light rays: It has fully passed the TÜV Rheinland software and hardware low blue light certification and flicker-free certification, and the light is reflected into the eyes many times, which is soft and not dazzling, and can eliminate 99.9% of harmful stray light.
02 Standards-led, safe and effective
The "Technical Specification for Desktop Television Electronic Display Equipment" (T/ZSA209-2023) led by Naidejia has been approved for release and implementation, which is the first technical standard for television in the field of myopia prevention and control in mainland China, to ensure the effectiveness and safety of television products in myopia prevention and control.
Highlight 3: "Use distant images to have vision" academic sharing
Cheng Dewen
Founder and CEO of Naidejia, Chief Scientist, and national leading talent
Professor and doctoral supervisor of Beijing Institute of Technology
On the morning of April 13, Professor Cheng Dewen, founder and CEO of Naidejia, shared the theme of "Vision and AI" at the International Forum on Artificial Intelligence Application and Development. He believes that in the face of the severe situation of myopia prevention and control, artificial intelligence technology should be fully applied in the field of ophthalmology, from the early myopia screening and prediction, auxiliary ophthalmic diagnosis, intelligent vision detection and evaluation, intelligent vision rehabilitation training and other ophthalmic disease processes.
Based on freeform optical technology, the first far-sighted image product of Naidejia converts short-range eyes into long-distance eyes, improves near-range eyes, which is the most important factor causing myopia, and plays an important role in the adjustment and choroidal thickening of myopic children. At the same time, it can also prevent digital eye strain caused by watching videos up close. Through the integration of artificial intelligence technology, vision television combines various functions such as vision training, AI inversion, recognition projection, etc., to achieve more intelligent and accurate myopia prevention and control. In the future, Naidejia will further explore more possibilities for the occurrence and development of myopia by reducing the load of ocular DH, improving accommodation, and reducing visual stimulation, so as to help the visual health of the whole people.
