1, the product design principle is different.
The principle adopted by Zeiss Chang Joy is the defocus theory in optometry, which can affect the correction of myopia "hyperopia drift", send a signal to the eyes, and slow down the development of eyeball axis elongation, thus slowing down the development of myopia. On defocus theory and Zeiss's principle of changing into Changle, that is to say, myopia is that the image of distant objects focuses in front of the retina, resulting in blurred far vision.
The principle adopted by Zeiss Chang Yue is the accommodation theory in optometry. It is a progressive multifocal lens specially designed by Zeiss for teenagers. Accommodation theory means that people's eyes are relaxed when they are far away, but they have to adjust when they are near, so they will cause eye fatigue, and progressive multifocal lenses are designed to alleviate this fatigue.
These products are suitable for different people.
Zeiss became Changle to control the excessive growth of children's eye axis, and Zeiss grew to relieve children's eye fatigue. If the child's eye axis grows too fast, then choose Changle of Zeiss. If the child's myopia is caused by eye fatigue, then grow up with Zeiss. You can do an A-ultrasound for your eyes and look at the length of the eye axis. Determine whether there are problems in eye adjustment, acquisition and image fusion.
These products are suitable for people of different ages.
Cheng Changle is suitable for children aged 6- 16, and the growth is suitable for children aged 16. Growth music can effectively control the degree increase. If the adjustment fails, you can use growth music. If a 7-year-old child is nearsighted 100 degrees, it will become 600 degrees when he 16 years old. If the growth of myopia can be controlled at 50%, the child will be nearsighted at 300 degrees.
Caisi grow up.
The lens is constantly innovated and upgraded, giving new functions on the basis of classic design. 20 17, Zeiss lens was upgraded with anti-ultraviolet function; On 20 18, a professional version of growth music was released, which conforms to the characteristics of Asian teenagers. In 2020, Zeiss Optics introduced a diamond cube defense film through rapid research and development, which can inactivate 99.9% of viruses and bacteria on the lens surface and make the lens achieve antibacterial and antiviral effects.
Zhang Lei, global product manager of Zeiss Optics Group, introduced that Zeiss Changle Enhanced Edition was upgraded on the basis of the classic version of Growing Music, with an average defocus of 44%, a defocus area of 80% and a stronger functional area.
Based on the research of the University of Tubingen, Germany, Zeiss Changle enhanced lens can effectively stimulate choroidal thickening, and has a good expectation of myopia prevention and control effect, which can provide a more personalized and targeted myopia management plan for adolescent wearers with different myopia risks.
Ouyang Lu, head of Zeiss Optical China R&D Center, introduced the function of Zeiss diamond cube defense film with the help of experimental video cooperated with Guangzhou Institute of Microbiology, which is the standard coating for Cheng Changle's reinforced lenses. It can effectively inactivate 99.9% viruses and bacteria attached to the lens surface, automatically resist bacteria and viruses, and add an extra defense guarantee for children's health.
