Harmonic diffractive Alvarez zoom smart glasses

Abstract

The invention discloses harmonic diffractive Alvarez zoom smart glasses. The harmonic diffractive Alvarez zoom smart glasses comprise a glass frame and lenses, wherein the lens on each side is formedby a harmonic diffractive Alvarez lens group, one harmonic diffractive Alvarez lens group consists of two lenses, and each lens is provided with a harmonic diffractive micro structure surface; each lens is fixed on a guide rail of the glass frame by virtue of a sliding block, and one or two of the two lenses can slide freely on the guide rail of the glass frame; and the harmonic diffractive microstructure surface is obtained by removing a phase difference of the Alvarez lens. By adopting the harmonic diffractive Alvarez zoom smart glasses, the focal power can be automatically adjusted according to an observation distance of a wearer for a target, so that the user can observe the target at a most comfortable state, the fatigue of eyes muscles can be alleviated, and an aim for preventing the shortsightedness of adolescent with normal vision can be achieved.

Description

Technical field [0001] The invention relates to a zoom smart glasses, in particular to a zoom smart glasses using a harmonic diffraction Alvarez lens group. technical background [0002] According to a special press conference held by the National Health Commission on June 4, 2018, the number of myopia in my country has exceeded 450 million, and the incidence of myopia shows a trend of early age, rapid progress, and deepness. Among them, the incidence of myopia in primary school students is about 30%, and that of college students is about 90%. Using eyes at close range is considered to be the first risk factor affecting the development of myopia. At present, electronic products are increasingly entering people’s lives. The adolescent stage is a critical period for the development of refractive status and a period of heavy learning. Adolescents have poor self-control ability in the use of electronic products, resulting in an increasing proportion of young people’s myopia. The ph...
