Description
Technical Field
The invention relates to the field of automatic zooming liquid glasses, in particular to electromagnetic mechanical zooming glasses for preventing or delaying myopia.
Background
A research report of world health organization in 2018 shows that myopia patients in China currently reach 6 hundred million, and the myopia rate of teenagers is the first in the world. The myopia rates of high school students and college students exceed seven percent and rise year by year, and the myopia rate of primary school students is close to 40 percent.
As early as 2012, the prevalence rate of myopia of teenagers in China is the first place in the world. It is estimated that by 2020, the number of Chinese shortsightedness will rise dramatically to 7 billion.
One theory of accommodation may explain the cause of myopia: during near work, the accommodative and collective action of the intraocular and extraocular muscles on the sclera increases intraocular pressure. Sustained ocular hypertension may lead to axial growth and axial myopia.
In order to prevent myopia caused by continuous near distance use, the prior art variable focus lens technology can relax the eye by adjusting the focal length of the lens. The zoom lens is divided from its driving manner, and is mainly classified into a force zoom lens and a piezoelectric electro-zoom lens.
The optical and laser education research center of florida university in the united states proposes a force-induced zoom lens that drives a lens using a servo motor. The servo motor compresses the rubber film by rotating and pulling the rope, the lens film is deformed due to extrusion so that the focal length is changed, and the focal length change time is short and is about 30 ms. The piezoelectric zoom lens realizes zooming by utilizing the deformation of piezoelectric ceramics in a piezoelectric actuator, and the piezoelectric ceramics deform under different voltages, so that a transparent film covered outside a fluid is pressed, and the curvature of the liquid lens is changed.
The force-induced zoom lens drives the lens in a servo motor mode, is complex in structure, occupies large space and is poor in applicability in the field of variable-focus glasses. The piezoelectric zoom lens realizes zooming by utilizing the deformation of piezoelectric ceramics in the piezoelectric actuator, and the deformation quantity of the piezoelectric ceramics generated under the action of an electric field is very small and does not exceed one ten million of the size of the piezoelectric ceramics at most, so that the application of the piezoelectric zoom lens in the field of variable-focus glasses is limited.
