Indeed, the prevalence of myopia progression is becoming a serious problem, especially in Asia: almost 90% of young people develop myopia before the age of 20.
Moreover, this is a global trend. In 2050, nearly 50% of the world’s population may be myopic.
To address this problem Hongchen has developed the most comprehensive myopia management spectacle lens portfolio, specially designed for children aged 6 to 12.
Treatments to slow or stop progression of nearsightedness
Myopia control eyeglasses lenses. It is an innovative spectacle lens for myopia control, and designed for teenagers under 18. It uses three core technologies to control myopia progression, and provides clear vision and myopic defocus simultaneously at all viewing distances.
(1) How do the myopia control lenses that can help slow or prevent myopia progression?
Myopia defocus control technology is the answer.
Well from the pictures above you can find — it can change the way light focuses on the retina between the central and peripheral retinal areas. Peripheral defocus theory suggests that this designs work at controlling myopia because they create that all important peripheral myopic defocus, interrupting the feedback loop for the eye to continue lengthening that is our bane in glasses and single vision lens wear.
