Problems solved by technology

However, these glasses are mostly used for the qualitative application of convex lenses and prisms to reduce the adjustment and concentration, but they have not done a good quantitative study on the relationship between them and the reading distance, eye position and interpupillary distance, so that the inner and outer eye muscles and ciliary muscle not fully relaxed
At the same time, the glasses are heavy and cannot be used far away, so the prevention and control effect is not perfect

Embodiment 1 to 5

[0031] Examples 1 to 5: see Figure 1 ~ Figure 4 , the multifunctional myopia control mirror contains a frame and a lens. The lens is divided into three optical areas from top to bottom, including the upper photometric area 1 for far use, the middle area (computer work area) 2 and the lower reading area 3 for near use. The optical center of the far photometric zone 1 is vertically downward to the optical center of the middle zone 2 and the optical center of the near zone 3. Among them, the optical center power of the central area is the distance optical center plus +1.00D or +1.50D, the near optical center is the distance optical center plus +2.50D or +3.00D, and the central area (computer work area) Add a base-inward prism 1.0×pupillary distance (cm) △ or 1.5×pupillary distance (cm) △, and a base-inward prism 2.5×pupillary distance (cm) △ or 3.0×pupillary distance ( cm)△.

[0032] The following is a list of five examples according to different situations:

Embodiment 6

[0035] Embodiment 6: A cuboid telescopic part with a length of 10-20 mm (that is, a controllable telescopic nose pad) is replaced at the nose pad of the spectacle frame, and the telescopic part is vertically installed at the position of the original arm rest. The outer casing 11 of the telescopic part is prism-shaped with a width and thickness of 3-9mm, and four hemispherical steel balls 13 are installed in the interior sequentially from top to bottom. The sheet 12 is connected to the nose pad 5 through the legs 10. The wave spring sheet 12 moves up and down to change the height of the nose pad. Smooth steel sheet 9 can reduce the resistance that spring sheet moves, prolongs service life.

[0036] Among them, the distance between the hemispherical steel balls is 3 ~ 8mm, and the shape of the wave spring leaf is coordinated with the distance and height of the hemispherical steel balls, whichever is not automatic sliding. Use your fingers to lightly press the bridge of the nos...

Abstract

The invention relates to a multifunctional myopic control eyeglass. The eyeglass which comprises a glass frame with height-adjustable nose supports, and eyeglasses is characterized in that: each eyeglass comprises an upper far luminosity zone, a middle zone and a lower close reading zone; and there is a visual channel with two degree changes, wherein one degree change is between the optical center of the upper far luminosity zone and the optical center of the middle zone just below the upper far luminosity zone, and the other degree change is between the optical center of the middle zone and the optical center of the close reading zone just below the middle zone. The eyeglasses are specially divided into three zones for the zero adjustment and the zero aggregation of reading and writing in the invention, so problems of the adjustment and the aggregation of close range reading and writing are thoroughly solved, the visual fatigue is eliminated, and myopia and degree increase are prevented, thereby present computer times of the comprehensive eye utilization are complied. The multifunctional myopic control eyeglass which allows previous neglected computer groups to be substantially facilitated allows the visual field to be clear, real and stable through the humanized zone height of each zone of the eyeglasses. The three zones which are used for cooperating with the adjustment of the eyeglass frame allow an image jumping phenomenon to be avoided. The wearing position of the eyeglass is accurate to guarantee the correct utilization of each zone, prevent the generation and the development of myopia caused by the fatigue of internal and external muscles of eyes and ciliary muscles.

Description

technical field [0001] The invention relates to glasses for preventing and controlling myopia, in particular to a multifunctional myopia controlling mirror for students and computer workers. Background technique [0002] The etiology of myopia: environmental factors, genetic factors and others. Among them, myopia caused by environmental factors is the most common, and it is mainly caused by excessive close work. Long-term close work mainly leads to fatigue of the internal and external ocular muscles and ciliary muscles, manifested as excessive and / or uncoordinated adjustment and collection. [0003] When the corrected emmetropia or myopia eyes gaze at the distance, the inner and outer ocular muscles of the eyes are in a relaxed state, the visual axes of the eyes are parallel, and the set is zero. The ciliary muscles of both eyes are also in a state of complete relaxation, and at this time the adjustment of the lens of the eye is zero. The pressure inside the eye is not ch...
