Description
Technical Field
The utility model relates to myopia glasses, in particular to functional glasses for preventing and controlling myopia and delaying myopia development.
Background
Refractive error is the inability of the eye to form a clear object image on the retina after the far parallel rays pass through the refractive effect of the eye without accommodation, and to image the far object before or behind the retina, thus seeing the far object blur, which includes hyperopia, myopia, and astigmatism. The refractive error can be corrected by the optical lens, so as to achieve the clear effect of seeing the hyperopia object.
Myopia is the most common type of ametropia, meaning that when the eye is at rest in accommodation, parallel rays from beyond 5 meters pass through the refractive system of the eye, focusing on the front of the retina, with higher degrees of myopia, the farther the focal distance from the retina. Because the focal point is not on the retina, near vision looking at distant objects is blurred, but near vision looking at near objects is clear.
The degree of myopia of most children and teenagers can be increased every year, the degree of progress of the children and teenagers of different ages is different every year, and the main reason for the continuous development and increase of the degree of myopia of the children and teenagers is as follows: because of long-time short-distance eyes, according to the mechanism of eye regulation, when the eyes are seen, the ciliary muscles need to be regulated to a certain extent, and long-time short-distance eyes can lead the ciliary muscles to be tired and spasms along with the regulation state, and the ciliary muscles can be tired along with time, so that myopia, namely axial myopia, is generated and developed.
Because the children and teenagers with myopia do not find in time and correct with the glasses, wearing an inappropriate correcting lens, and focusing the object image of a distant target in front of or behind the retina when looking far, the vision is blurred and unclear, and the retina is induced to develop to the rear of the eyeball due to the characteristic of chasing focus, so that the eye axis is lengthened, and the degree of myopia is further increased, which is called defocus myopia.
In summary, the increase in myopia is caused by excessive accommodation of the ciliary muscle and hyperopic defocus of the retina.
