Abstract
The utility model provides a pair of gradual multi-focal eyeglasses, two lenses are respectively arranged in an eyeglass frame, upper, middle and lower areas are arranged on each lens, the upper light region adopts a concave lens, and is a myopia correction area, to satisfy long-term view; the middle light region is a transition area, the lower light region adopts a convex lens, and is a myopia remedy area, to satisfy the short-term view, to release and adjust eyes, and to perform the function of preventing and controlling the myopia increment. If the myopia diopter is higher, the diopter of the positive lens at the lower part is lower; if the myopia diopter is lower, the diopter of the positive lens at the lower part is higher, thus, the gradual multi-focal eyeglasses which can satisfy different diopter states can be worn by myopia patients, the patients can not be comfortable if the gradual multi-focal eyeglasses are worn permanently, and the gradual multi-focal eyeglasses both can perform myopia correction and myopia remedy.
Description
Technical field
The utility model relates to a kind of glasses, relates in particular to a kind of progressive multi-focal glasses.
Background technology
The eighties in 20th century, Shanghai and Xuzhou two tame ophthalmology research unit uses lower degree convex lens control myopia, and effect is obvious, safe and effective really, obtain Ministry of Education of the state's body and defend the abundant affirmation of looking light expert group of department's tissue, but this glasses can only be seen nearly usefulness, will form like this to see needs one secondary near-sighted glasses far away, see nearly needs one secondary convex lens, if wear, need vary during use, very inconvenient, be not easy to be accepted by the teenager.
All there are shortcoming separately again in bifocus that has risen since 2003 and multifocal spectacles, and picture appears in bifocal slasses easily jumps, no matter how much design myopia of multifocal spectacles is spends, add all down to be+1.50
DOr+2.00
D, that is to say no matter patient's myopia is what and spends, see and all reduce 1.50 when near
DOr 2.00
D, do not design respectively according to each dioptric physiological situation.So control and result of treatment are unsatisfactory.Therefore we are not difficult to draw such conclusion, and it is comfortable clear to have only lens design to get, and the student just can take like a shot, and just can adhere to wearing for a long time, just can play excellent curative.
Summary of the invention
The purpose of this utility model provide a kind of see far can myoporthosis, see closely can myopia the progressive multi-focal glasses.
The utility model is achieved through the following technical solutions, design a kind of progressive multi-focal glasses, two eyeglasses place mirror holder respectively, described eyeglass respectively is provided with three zones of upper, middle and lower, the glazing district is concavees lens, is the myoporthosis district, and the centre is a transitional region, the Xia Guang district is convex lens, is the myopia district.
Progressive multi-focal glasses of the present utility model have the following advantages:
1, the ingenious part of this eyeglass design is to have on a pair of glasses three zones, and the glazing district adopts concavees lens, is the myoporthosis zone, sees far to satisfy; The centre is by the transitional region of concavees lens to convex lens, and the Xia Guang district adopts convex lens, is the myopia zone, sees closely to satisfy, and helps eyes to loosen adjusting, plays the effect of prevention and the intensification of control myopia.
2, the ingenious part of this eyeglass design is, its near-sighted diopter is high more, and its underpart positive lens diopter is low more; Its near-sighted diopter is low more, its underpart positive lens diopter is high more, so more the A nearsighted person that can satisfy different refractive status wears, and putting on can be more comfortable, does not have uncomfortable sensation, the more pleased acceptance of student like this, can adhere to wearing, wear for a long time, can play better effect, accomplish that myoporthosis and myopia neglect neither.

Embodiment
With reference to Fig. 1, progressive multi-focal glasses of the present utility model, two eyeglasses place mirror holder respectively, described eyeglass respectively is provided with three zones of upper, middle and lower, and glazing district 1 is concavees lens, is the myoporthosis district, the centre is a transitional region 2, and Xia Guang district 3 is convex lens, is the myopia district.These glasses are implemented processing and are divided into right eye and left eye, installation adds man-hour glazing district 1 will be by far joining surely with the interpupillary distance design, and Xia Guang district 3 lens will according to the set of eyes cross strong or convergence insufficiency respectively additional substrate 2.25 prisms 4 inside or that substrate is outside finish fixed with addition of the worker, regulate and the eyes set to help eyes, reduce eye fatigue, reach the effect of treatment and control myopia progression.Mostly the pseudo-myopia eyes are to gather strong, and mostly the true myopia eyes are convergence insufficiency.
