Embodiment Construction

[0051] Such as figure 1 As shown, a kind of sandwich type Alvarez zoom smart glasses, including frame and lenses; the lenses on each side are composed of a harmonic diffractive Alvarez lens group 4, and a harmonic diffractive Alvarez lens group is composed of three lenses, each lens is set There is a harmonic diffraction microstructure surface; the outer two lenses of each group of lenses are fixed on the frame and form a sealed space, the middle lens is fixed on the sliding groove 2 of the frame through a slider, and the middle lens is perpendicular to the light Sliding in the direction of the axis, the harmonic diffraction microstructure surface is obtained by removing the phase difference by an Alvarez lens; the left side of the front of the mirror frame is provided with a first sensor 1, the right side of the front of the mirror frame is provided with a third sensor 5, and the middle of the front of the mirror frame is provided with a sensor 5. There is a second sensor 3,...

Abstract

The invention discloses sandwich type harmonic-diffraction Alvarez variable-focal-length intelligent glasses which comprise a spectacle frame and lenses, wherein each lens is formed by a harmonic-diffraction Alvarez lens assembly, each harmonic-diffraction Alvarez lens assembly is composed of three lenses, each lens is provided with harmonic diffraction microstructure surface, two lenses on the outer sides of each group of lenses are fixed to the spectacle frame to form a sealed space, the lens in the middle is fixed to a guiding rail of the spectacle frame through a sliding block, the lens inthe middle can slide in the direction perpendicular to the optical axis, and the surface of each harmonic-diffraction microstructure is prepared by removing phase difference of the Alvarez lens. Thepurpose of automatically adjusting the focal power according to the target observing distance of a wearer is achieved, a user can observe targets in the most comfortable state, eye muscle fatigue is relieved, and the purpose of preventing myopia can be achieved for teenager users with normal vision.

Description

technical field [0001] The invention relates to smart glasses, in particular to smart glasses using a harmonic diffraction Alvarez lens to zoom. technical background [0002] The National Health and Medical Commission revealed at a special press conference on June 4, 2018 that the number of people with myopia in my country has exceeded 450 million, and the onset of myopia presents a trend of early age, rapid progression, and deep degree. Among them, the incidence of myopia among primary school students is about 30%, and that of college students is about 90%. Near-sightedness is considered to be the first risk factor affecting the development of myopia. At present, more and more electronic products have entered people's lives. Adolescence is a critical period for the development of refractive status, and it is also a period of heavy learning. Teenagers have poor self-control ability in using electronic products, resulting in an increasing proportion of young people with myop...
