Problems solved by technology

[0002] Presbyopic glasses or myopia glasses or farsighted glasses in the prior art all are glasses that change regulation, and shortcoming is that the regulation that only changes eyes does not change the collection of both eyes (see figure 1 , figure 2 )
When wearing glasses, the gap between the cooperation and habit of binocular convergence and adjustment is too large, which will make the eyes feel uncomfortable and easy to fatigue
Such as common phenomenon: in the early stage of wearing presbyopic glasses or myopia glasses of the prior art, because the glasses have destroyed the habit of coordination between the original collection and adjustment of the eyes (see image 3 ), so it will feel uncomfortable and easy to fatigue, long-term wearing glasses to form a new habit (see Figure 4 ) to get used to it, but taking off the glasses and looking at things with the naked eye will feel uncomfortable because of breaking the new habit. feeling sick and tired easily
The existing technology "ZL95201944.2 Vision Regression Mirror" also destroys the coordination habit between the original collection and adjustment of the eyes, expands the contradiction between collection and adjustment, and cannot make the eyes feel comfortable and hardworking when watching

Embodiment 1

[0056] Embodiment 1: the glasses shown in Figure 21 are collection glasses that improve the collection function of other presbyopia glasses, and its structure is as shown in Figure 29, and the spectacle lenses of the collection glasses are two symmetrical refracting prisms 1 (if the refracting prisms The deflection angle is decomposed into horizontal direction and vertical direction, then the components in the horizontal direction are opposite in direction, equal in size and not equal to zero; the components in the vertical direction are in the same direction, equal in size, can be equal to zero or not equal to zero. The base of the refracting prism can be all inwards, or all outwards, or all inwards, etc.), the bases of these two refracting prisms 1 are all inwards in this example, and the deflection angles are all 9 prism degrees (1 prism in the Platts prism calibration method degrees is approximately equal to 0.5729 degrees). Connecting parts 2 are arranged on the spectacle...

example 2

[0057] Example 2: As shown in Figure 23, the difference between collective glasses and ordinary glasses is that the spectacle lenses are two left-right symmetrical collective spectacle lenses 1, and the collective spectacle lenses are composed of two prisms of different materials closely connected together to reduce chromatic aberration Refracting prisms, the bases of the two refracting prisms 1 are both inward and downward, the deflection angle is 12 prism degrees, and the magnitude of the horizontal component of the deflection angle is 9 prism degrees. The advantage of the base of the refracting prism facing inwards rather than the bases facing inwards is that it can reduce the degree of bowing the head when studying. The spectacles in this collection can be separately used as presbyopic spectacles for those who are accustomed to often wearing myopia spectacles or glasses for nearsightedness. It can also be used as glasses to improve other presbyopic glasses collection funct...

example 3

[0058] Example 3: As shown in Figure 24, the difference between the collection glasses and ordinary glasses is that the glasses frames (8 and 7) can be equipped with two layers of glasses, and the fixed glasses frame 7 has an empty position 4 for installing the other two lens glasses. , there is also a rotatable bottle cap type mirror frame 8 in front of the fixed spectacle frame, and there are two collection spectacle lenses (i.e. refracting prism spectacle lenses) 1 in the bottle cap type spectacle frame, and in the bottle cap type spectacle frame and mirror There is a mark indicating the orientation of the base of the deflection angle on the shelf. Rotating the bottle-cap type frame can change the base orientation of the refractive prism lens and stabilize it in a left-right symmetrical position. The deflection angle of the refracting prism is 10 prism degrees.

Abstract

The invention provides a collection spectacle lens, a collection eyeglasses and an application thereof and belongs to the technical field of the eyeglasses. The invention is characterized in that the spectacle lens of the collection eyeglasses is the collection spectacle lens and the collection eyeglasses changes binoculus collection with the collection spectacle lens, moreover, the collection glasses can match with a presbyopia eyeglasses or myopia eyeglasses of the prior art and improves the shortcomings thereof; the invention can make the eyes feel comfortable without fatigue when in watching. The invention is a comfortable type presbyopia eyeglasses or comfortable type myopia eyeglasses. The teenager can keep out myopia when in learning with the invention.

Description

technical field [0001] The invention relates to the technical field of spectacles, and relates to spectacles used for emmetropic eyes, myopic eyes, hyperopic eyes, presbyopia and the like (orthotropic eyes). The spectacle lens of the present invention is a raw spectacle lens for preparing the spectacle of the present invention or a shaped spectacle lens to be mounted. Background technique [0002] Presbyopic glasses or myopia glasses or farsighted glasses in the prior art all are glasses that change regulation, and shortcoming is that the regulation that only changes eyes does not change the collection of both eyes (see figure 1 , figure 2 ). When wearing glasses, if there is too much difference between the coordination and habit of the eyes' concentration and adjustment, the eyes will feel uncomfortable and easily fatigued. Such as common phenomenon: in the early stage of wearing presbyopic glasses or myopia glasses of the prior art, because the glasses have destroyed t...
