Abstract

The invention relates to the technical field of composite mirrors, in particular to a longitudinal chromatic aberration-based prismatic composite mirror. The prismatic composite lens based on longitudinal chromatic aberration determines the required additional imaging refractive power by calculating the biological measurement data of the eyes of a user, the cornea red light refractive index and the cornea blue light refractive index so as to determine the diopter of the lens, so that the image is located in front of the retina, the self-adaptive mechanism of the eyes is activated, and the ocular axis is shortened; therefore, the myopia degree is effectively reduced, the development of the myopia can be prevented and controlled, the progress of the myopia is reversed to a certain extent, and the myopia problem is fundamentally solved. Meanwhile, the prism degree of the prism-transparent composite lens is increased, so that the diopter of the lens is prevented from being influenced by rotation of eyes, and the correction effect of the prism-transparent composite lens is further improved. A non-invasive correction mode is adopted by the prism-transparent composite mirror based on the longitudinal chromatic aberration, no operation is needed, and the operation risk is avoided.

Description

Technical Field

[0001] The invention relates to the technical field of composite mirrors, and in particular to a prism-transmitting composite mirror based on longitudinal chromatic aberration. Background Art

[0002] Currently, common methods of correcting myopia include wearing frame glasses, contact lenses, and surgical methods such as laser corneal refractive surgery (LASIK). Although frame glasses and contact lenses can provide good vision correction effects, they cannot prevent the development of myopia. Surgical methods are effective for some patients, but are not suitable for everyone and have certain surgical risks.

[0003] In terms of myopia prevention and control, in recent years, technologies such as defocus lenses and orthokeratology lenses (OK lenses) have emerged, which mainly delay the progression of myopia by changing the refractive state of the eyes. However, although these technologies are effective in preventing and controlling the progression of myopia, they cannot reverse the development trend of myopia.

[0004] The human eye has a phenomenon of longitudinal dispersion. When looking into the distance, the image will fall in front of the retina. At this time, the image in the red light band is clearer, and the eye's adaptive mechanism will be activated to improve the visual imaging quality by adjusting the axial length. This mechanism of axial shortening is expected to help some myopic patients reduce the degree of myopia. Summary of the invention
