Problems solved by technology

Common phenomenon: in the initial stage of wearing the prior art myopia glasses, because the glasses have destroyed the habit of coordination between the original collection and adjustment of the eyes ( image 3 ), so you will feel uncomfortable and easily fatigued, wear glasses for a long time to form a new habit ( Figure 4 ) before you can get used to it, but taking off the myopia glasses and looking at things with the naked eye will feel uncomfortable because of breaking the new habit. Glasses can also feel uncomfortable and tire easily

example 4

[0042] Example 4 of spectacle lenses: ( Figure 15 is to help understand Figure 16 schematic diagram, Figure 16 is a schematic diagram of a compound spectacle lens) Figure 15 The above figure is an achromatic prism 12 that can eliminate or weaken chromatic aberration, which is composed of a prism 11 and another prism 10 (another material) whose base faces the opposite direction. (12 is composed of two different materials. ), the following figure is a schematic diagram of the prior art myopia lens 2. Figure 16 It is a schematic diagram of an achromatic composite spectacle lens 13 composed of an achromatic prism 12 and a prior art myopia spectacle lens 2 (the composite spectacle lens can be made of two kinds of materials or three kinds of materials), and it is made of two kinds of materials with different refractive indices. The formed two refracting prism bases are stacked and bonded opposite to each other to form a prism for eliminating chromatic aberration or reducing ...

Abstract

The invention relates to a myopic eyeglass, and belongs to the eyeglass technical field. The myopic eyeglass includes a spectacle lens and a support for supporting the spectacle lens, and is characterized in that the distance between an optical center of the spectacle lens facing a left eye and that of the spectacle lens facing a right eye is smaller than a near pupillary distance of a user, equivalent to the myopic spectacle lens in the prior art combined with a prism with an external base, wherein the spectacle facing the left eye and the spectacle facing the right eye may be separated compound spectacle lenses or compound spectacle lenses united as one, or may be bifocal lenses or multifocal lenses. The myopic eyeglass not only improves the adjustment of the eyes but also improves the binocular gather, improves the observation effect of the eye, and enables the eye to feel comfortable and antifatigue.

Description

technical field [0001] The invention relates to the technical field of spectacles, in particular to spectacles for myopia. Background technique [0002] The myopia glasses of the prior art are glasses that change adjustment, and require that the distance between the optical centers of the left and right spectacle lenses be equal to the interpupillary distance, and the shortcoming is that only the adjustment of the eyes is changed but the collection of the eyes is not changed ( figure 1 ). There is a habit and law of synchronous linkage and coordination between the convergence and adjustment of the eyes. If this habit is broken and the gap between the actual coordination and the habitual coordination between the convergence and adjustment of the eyes is too large, the eyes will feel uncomfortable and easily fatigued. Common phenomenon: in the initial stage of wearing the prior art myopia glasses, because the glasses have destroyed the habit of coordination between the origin...
