Multifunctional presbyopia glasses

Abstract

The invention discloses a multifunctional presbyopia glasses, comprising a frame and two multifunctional lenses; wherein the multifunctional lenses are divided into four types of zones: a lustering zones arranged above the lenses, a transition zone arranged in the middle of the lenses, a delustering zone arranged below the lenses and two astigmation zones arranged at the two sides of the lenses. The multifunctional presbyopia glasses of the invention has clear and continuous visual sense on objects from far distance to near distance and has the characteristic of being beautiful and comfortable.

Description

technical field [0001] The invention relates to spectacles, in particular to a multifunctional presbyopic mirror. Background technique [0002] Presbyopia can be corrected with regular presbyopia glasses, bifocals, and progressive addition glasses. [0003] Ordinary presbyopic glasses (single vision lenses) have the disadvantage of blurring vision. A considerable number of people who wear single-vision presbyopia glasses have a narrow field of vision and feel visual fatigue after wearing them for a long time. Especially for wearers who do indoor activities for a long time, they often feel various discomforts, such as a pair of glasses with clear reading at close range when used for watching computers, playing mahjong, watching TV or lying down to read books, etc. In indoor situations, due to the longer distance, there will be a certain degree of unclearness immediately, that is, the discomfort caused by the lens adjustment function. [0004] The main lens of the bifocal g...

Problems solved by technology

However, bifocal glasses have the disadvantage of being unsightly, and there is a phenomenon of "light jump" in bifocal lenses

[0005] Although the progressive multifocal glasses solve the above problems, since a small number of people with special luminosity must be considered to be able to use them, the design must inevitably consider the broad-spectrum performance, which leads to the limitation of narrow lens channel design, which requires a lot of technical requirements for assembly and optometry. High, not easy to adapt, and the manufacturing cost is expensive, it is difficult for ordinary consumers to accept, it is not conducive to popularization and promotion, and it is not suitable for mass presbyopia production
