Description

Glasses for preventing myopia from deterioration and reducing myopia degree

Technical Field

The utility model belongs to the technical field of glasses, concretely relates to prevent that myopia person's eyesight worsens and reduce glasses of myopia number of degrees.

Background

Myopia is the condition that under the premise of refraction stillness, objects at a distance cannot converge on the retina, and a focus is formed in front of the retina, so that vision deformation is caused, and the objects at the distance are blurred.

At present, more and more myopic eyes are used, and the myopic eyes present a low-age situation. However, the distance between the pupils of the two eyes of a person varies with age, and when a fixed frame is worn, the center distance of the lenses of the glasses is not consistent with the interpupillary distance, the glasses have to be replaced frequently, otherwise, the vision is impaired, and the most direct result is that the number of the eyes is increased.

The existing myopia prevention and control glasses mainly have the following defects:

firstly, focusing on the problem of photopic vision only, focusing on the problem of accommodation and convergence, solving the problems of adaptability and wearing convenience, but not finding the root of myopia deterioration, and not deeply exploring how to cause continuous deepening and deterioration, and certainly thinking that the short-distance work such as television and computer reading causes visual fatigue and diopter increase, which is a thick and shallow and unproductive conclusion, and the neural problem caused by high convergence is not noticed at all.

Secondly, the existing design is limited to make form changes on the near-use lens, the half-and-half design, the external hanging design and the like cause great inconvenience for the user, the adaptability is poor, and the efficiency for using the lens is extremely low.

Third, there is no real use of the time of daily life for a large period of time, and a myope will wear traditional high-concentration eyeglasses indoors or will recover a high-concentration eye movement habit, which is equivalent to a close-looking training time.

Therefore, the measures adopted at present for preventing myopia or preventing vision deterioration are both temporary and permanent, and the appearance is obvious, the effect is certainly poor, and the effect is uncertain repeatedly, and even the vision of the myopia is lower than the beyond control.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a: to solve the problems of the prior art, there is provided glasses for preventing deterioration of eyesight of a myope and reducing the degree of myopia.

In order to achieve the technical purpose, the utility model adopts the technical scheme that:

prevent myopia person's eyesight and worsen glasses of near-sighted degree, including a pair of near-sighted glasses and a pair of far-sighted glasses, the lens of near-sighted glasses with the lens of far-sighted glasses forms by lens and 3 prisms are compound, 3 prisms are superpose in proper order to one side that the eyes were kept away from to lens by one side that lens are close to eyes, the lens clamp in the middle of 3 prisms, the base direction of 3 prisms all faces the nose side.

As an improvement, the diopter is below-3.0D, the lens of the near glasses is formed by compounding a lens with diopter of +0.50D and 3 prisms, the angles of the base directions of the prisms are 180 degrees for the left eye, 0 degree for the right eye, the far pupil distance of +3mm, and the far pupil distance is generally 49-70 mm.

As an improvement, the diopter is more than-3.0D, the lens of the near glasses is formed by compounding a lens with diopter of-1.50D and 3 prisms, the angle of the base direction of the prisms is 180 degrees for the left eye, 0 degree for the right eye, and the pupil distance for the far eye is-3 mm.

As an improvement, the lens of the far-distance glasses is formed by compounding a lens with 0.50D subtracted on the basis of far-distance diopter and 3 prisms, and the angles of the base directions of the prisms are 180 degrees for a left eye, 0 degree for a right eye and-3 mm for a far-distance pupil distance.

As a further improvement, the distance diopter is-0.50D to-15.00D.

the utility model provides a glasses have both solved the regulation problem of myopia person's eyes, have solved the high problem of gathering of myopia person's eyes again to let myopia person's eyes independently produce self-healing's power, both eradicated the eye and produced myopic factor, broken the inherent neural memory problem of myopia person again, and, the utility model discloses a glasses outward appearance like ordinary glasses, easily adapts to, and myopia person is willing to wear, in daily life study, seamless training, seamless resting changes the eye position, and the self-healing biological environment of seamless reconsitution eyes gradually reduces diopter, thereby suppresses the two tendencies of worsening of human field of vision and eyesight.

The utility model provides a pair of glasses, the setting up of 3 individual prisms makes the visual axis optical axis different, the interpupillary distance changes (or little), make extraocular muscle produce the autonomic power that the visual axis shift becomes when seeing near or seeing far, abduction epinasality, change extraocular muscle's inside and outside rotatory movement track, the inherent eye position of myopia is repaired to change, make the brain occipital lobe produce new memory eye position, thereby reactivate extraocular muscle activity mechanism, then liberation by the intraocular muscle of kidnapping, make whole eyes survive again, form new regulation and set mechanism, in cycles, along with the glasses of changing suitable special design data, gradually break the high set, reduce the set, thereby reduce near-distance diopter, promote eyesight, the field of vision enlarges, the trend of reversal human myopia evolution.

The utility model provides a pair of glasses, lens are formed by lens and 3 integrative compound of prism, see from the outward appearance, do not have the cross-over line, and the angle of the basement direction of the prism of controlling the eye is asymmetric design, and 3 the degree that individual prism changes the set size equals with the degree that lens change regulation size, uses near-purpose glasses when seeing near, uses far-away glasses when seeing far away, no matter see far away or see near, the set of both eyes always keeps synchronous linkage with the regulation cooperation, wears the utility model discloses a regulation of both eyes is the same with set cooperation law when glasses are seen book and bore hole are seen, and the user is no matter can feel comfortable from what angle of glasses seeing the thing, effectively alleviates eye fatigue.

It is to be noted that: the three prism amounts are the safest amount, less than 3 eyes can not generate the modification power, and more than 3 eyes can aggravate the latent external strabismus tendency of the myopia.
