Description
This utility model relates to a kind of glasses of controlling myopia progression.
Myopia is human common oculopathy, is defined as parallel rays clinically after the dioptric system flexion of eye, be imaged on retina before.Main and the excessive use of myopia development is regulated, and the elongated grade of axis oculi is relevant.
The glasses of control myopia progression have two classes both at home and abroad:
1, how burnt near-sighted control strip glasses are the many focuses glasses for the myopia that are assemblied on the common spectacles frame.Characteristics are: the first half myopia number of degrees of glasses are higher, and are clear when being convenient to see distant objects; The latter halfs of glasses myopia number of degrees are lower, need not use too much adjusting when making the patient see nearly thing, so the myopia progression that can avoid accommodative excess to cause.Shortcoming is, seeing needs spectacle-frame to be raised or watched attentively from the latter half of spectacle-frame when near, forgets with glasses the latter half as the patient and sees and see nearly thing with the first half, can increase adjusting and impels myopia progression.In addition, behind myopia progression, the multifocal ophthalmic that must in time more renew just can be seen distant objects clearly.
2, prism or lens myopia mirror are to utilize glasses for the myopia adding prism or hyperopic lens minimizing adjusting and set effect and control myopia progression.Characteristics are: adopt the common spectacles frame, and need be according to everyone different near-sighted number of degrees special eyeglasses customized.Major defect is the necessary special customized eyeglass of patient, and these glasses are only limited to customization people use and are not suitable for other myopes, needs the eyeglass that in time more renew behind myopia progression.
The purpose of this utility model is to provide a kind of adjusting power and convergence power that can be by the absent-mindedness human eye limit that myopia takes place, development, does not need to test specially to join and be fit to any false or addition type glasses that the true myopia patient wears.
This utility model is achieved in that it forms one by the empty focus lens of left side picture frame, right side picture frame, left side, the empty focus lens in right side, left side picture frame fixation hook, right side picture frame fixation hook, picture frame fixing spring device seven parts.The right side picture frame is connected with the right-hand member of picture frame fixing spring device, the left side picture frame is connected with the left end of picture frame fixing spring device, picture frame fixing spring device is between the left and right sides picture frame, right side picture frame fixedly drag hook is connected with the upper left side of right side picture frame, left side picture frame fixedly drag hook is connected with the upper right side of left side picture frame, and the empty focus lens in right side is embedded in the picture frame of right side, is positioned at the picture frame left side at the bottom of this eyeglass prism, the empty focus lens in left side is embedded in the picture frame of left side, is positioned at picture frame the right at the bottom of this eyeglass prism.
Below in conjunction with accompanying drawing and example this utility model is described in detail.
Fig. 1 is an axonometric chart of the present utility model
Fig. 2 is a structural representation of the present utility model
The figure number explanation:
The empty focus lens in picture frame 3-picture frame fixing spring device 4-empty focus lens 7-left side, picture frame fixation hook 6-right side, right side picture frame fixation hook 5-left side, 1-right side picture frame 2-left side
Consult shown in each view, this utility model is by right side picture frame 1, left side picture frame 2, and picture frame fixing spring device 3, right side picture frame fixation hook 4, left side picture frame fixation hook 5, the empty focus lens 6 in right side, the empty focus lens 7 in left side constitutes.Each structure fuses.The top central authorities of right side picture frame 1 are connected in the right-hand end of picture frame fixing spring device 3, the top central authorities of left side picture frame 2 are connected in the left side of picture frame fixing spring device 3, picture frame fixing spring device 3 is between the left and right sides picture frame, right side picture frame fixedly drag hook 4 is connected with the upper left side of right side picture frame 1, left side picture frame fixedly drag hook 5 is connected with the upper right side of left side picture frame 2, the empty focus lens 6 in right side is embedded in the right side picture frame 1, be positioned at the picture frame left side at the bottom of this eyeglass prism, the empty focus lens 7 in left side is embedded in the picture frame 2 of left side, is positioned at picture frame the right at the bottom of this eyeglass prism.
The utility model compares with each spectacles of at present domestic production, has following features:
1, the eyeglass of these glasses is empty focus lens, image can be treated to the image of similar infinity, so can alleviate adjusting The myopia that causes with set takes place, development.
