Myopia prevention and control of new "artifacts" popular, ophthalmology next 10 billion big single product to come?

2024-08-06

Since 2024, a new myopia prevention and control "artifact" has become popular on social platforms, namely: defocus soft mirror (also known as multi-focal soft mirror).

In the past, defocusing frame glasses were one of the most important means to prevent and control myopia. Defocusing frame glasses are convenient to wear, have a wide range of application, good prevention and control effect, and are relatively economical in myopia prevention and control products, but need to face the inconvenience caused by frame glasses to large movements or other activities.

With its remarkable prevention and control effect, and the convenience of wearing it only at night without affecting daily life during the day, the penetration rate in the field of myopia prevention and control has increased rapidly in recent years. However, the OK mirror needs to undergo strict examination before fitting, and not all patients are suitable; And the OK mirror is made of rigid high-oxygen permeability material, which requires a certain adaptation period, and some children can not even adapt to it.

Defocusing soft mirror has the advantages of the above two main products while avoiding its disadvantages. Firstly, both defocusing soft glasses and defocusing frame glasses are designed based on optical defocusing theory. The light passes through the correction area and focuses on the retina to form a clear focus. The light passing through the treatment area is focused in front of the retina to create peripheral myopic defocus to slow the growth of the eye axis. Secondly, the material of defocusing soft lens is similar to ordinary contact lenses, mostly hydrogel or silicon hydrogel, which is superior to OK lens in terms of wearing adaptation period and comfort, providing a new choice for patients who cannot wear OK lens and do not want to wear frame glasses.

According to the research data of the Shanghai Biomedicine Foundation, the 10 billion pieces of ophthalmic instruments are mainly concentrated in the "correction & prevention and control" large optical products, such as laser surgery and ICL surgery, OK mirror, contact lenses, defocusing lenses, etc.
