Description

Binocular visual mechanical training instrument

Technical Field

The utility model relates to an eyesight lifting means technical field especially relates to a binocular vision mechanical training appearance.

Background

Vision refers to the ability of the retina to resolve images. The quality of vision is determined by the amount of ability of the retina to resolve images, however, when the refractive medium of the eye (e.g., cornea, lens, vitreous, etc.) becomes cloudy or refractive errors (including myopia, hyperopia, astigmatism, etc.) exist, vision of the eye declines even when the retina functions well. Vision refers to the ability to resolve small or distant objects and subtle parts, the ability of the eye to recognize distant objects or objects is called distance vision, and the ability to recognize close small objects or objects is called near vision. In the health examination, the distant vision is mainly examined. Under certain conditions, the smaller the object that the eye can resolve, the greater the visual acuity, and the basic feature of vision is to discern the magnitude of the distance between two points.

Myopia is defined as the phenomenon that near objects are clear when viewed at near, and far objects are blurred when viewed at far, which is defined by profession as "the distance objects are focused before the retina after refraction by the eyeball, rather than forming a clear object image on the retina". Myopia is the most common eye disease of Chinese children, while the rate of continental high myopia is much higher than that of children in other countries and regions, and many eye diseases derived from high myopia are threatening the eyesight and eye health of many children. The far-sighted near object is focused behind the retina after refraction of the eyeball, and a fuzzy object image is formed on the retina. Therefore, the patient with presbyopia cannot see far or near clearly. Infants have few myopic eyes, more than 90% of preschool children are hypermetropia, most of which are physiological and are the manifestations of normal eye development. Hyperopia is pathological in 20% -25%, and is the main cause of poor vision and poor eye development of children. Amblyopia is a disease that seriously affects the visual function, which means that the eyeball has no obvious organic lesion, the far and near vision is less than 0.8, and the normal condition cannot be corrected. According to statistics, over 1500 million patients with amblyopia become a social problem which needs urgent attention.

Eyes are a window of soul, people can not leave the help of the eyes in study, work and life, however, with the increase of life pressure and age of people and incorrect eye habits and other factors, the eyesight of people is deviated to a certain extent. Although some problems can be solved by wearing the eyes, the eyesight recovery is not facilitated, and as the attention degree of people on the health of the people is improved, the people start to help the people to recover the eyesight through the eyesight training instrument. The common visual training instrument on the market has the advantages of single structure, humanized design, low use comfort, poor training effect and no contribution to visual recovery.
