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
The spectacle lenses used for preparing myopia glasses in the prior art are not easy to prepare myopia glasses of the present invention because their optical center coincides with the geometric center and the lens size is limited.

Embodiment 1

[0042] Embodiment 1: The difference between the myopia glasses and the prior art myopia glasses is that the distance between the optical centers of the left and right spectacle lenses is smaller than the user's near-pupillary distance. The polarizing lens is also a kind of "composite spectacle lens equivalent to compounding a prism on the myopia lens of the prior art", but the compound spectacle lens may not be the polarizing lens. A kind of myopia spectacles shown in Fig. 18 is respectively pasted a prism 1 with a base facing outwards on the front surface of the left and right two spectacle lenses 16 of the prior art myopia spectacles, that is, the spectacle lenses corresponding to both eyes are equivalent to the prism 1 from the base to the outside. The compound spectacle lens that outer prism 1 is combined with the concave lens sheet 16 of prior art myopia glasses to form. Wherein the two spectacle lenses of the prior art myopia glasses are all spherical spectacle lenses, a...

Embodiment 2

[0043] Embodiment 2: The difference between the myopia glasses shown in Figure 25 (front view) and Figure 26 (top view sectional view) and the prior art myopia glasses is that the eyeglasses are the composite eyeglasses of the myopia glasses of the prior art and a prism 6. The optical centers of the left and right compound spectacle lenses coincide with the connecting shaft 28 of the bridge of the nose. There is a rotatable connecting shaft 28 on the bridge of the nose of the spectacle frame. Rotating around the axis can change the distance between the left eye lens and the right eye lens. Distance and changing the orientation of the prism base in compound ophthalmic lenses. The orientation of the prism bases in the compound spectacle lenses for myopia glasses can also be all turned outwards downwards or outwards upwards with the rotation. The temples can also be rotated 29 degrees, so it can be used by people with different face shapes.

Embodiment 3

[0044] Embodiment 3: as shown in Fig. 20 (front view schematic diagram) and Fig. 21 (overhead sectional schematic view), the difference between myopia glasses and prior art myopia glasses is that the left eye glasses and right eye glasses corresponding to both eyes have the same optical center 21 (a concave lens) compound spectacle lens 22. The myopia glasses correspond to the left-eye lens and the right-eye lens of both eyes, which are integrated and integrally formed with the frame. The distance between the geometric center 23 and the optical center 21 of the spectacle lens corresponding to the left eye or right eye of the myopia glasses is greater than 1.5 centimeters (the optical center and the geometric center both refer to the position when looking at it from the front), and the myopia glasses are bilaterally symmetrical. The left spectacle lens and the right spectacle lens of the myopia glasses shown in Figure 20 (front schematic diagram), Figure 22 (top view sectional ...

Abstract

The invention relates to a pair of glasses for the shortsighted, belonging to the technical field of glasses. The invention is characterized in that the distance between focal centers of two eye glass lenses thereof is smaller than the shortsighted pupil distance of a user, and the eye glass lenses of the glasses for the shortsighted are polarized light and composite lenses. In the invention, the glasses for the shortsighted, belonging can improve observation effect and achieves comfortable and antifatigue feeling for the user.

Description

technical field [0001] The invention relates to the technical field of spectacles, and relates to spectacles for myopia and spectacle lenses for preparing myopia glasses. 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 destro...
