1, like product is generally all pressed gauged distance design, do not consider the student be accustomed to eye distance from, breaking away from the student influences result of use with the actual conditions of eye.

2, existing common lens type compound lens is because only use in reading study with when closely writing, and sees and can not use when far away.See that need far away join a secondary glasses for myoporthosis in addition, cause and use trouble, forget use easily, it is relatively poor relatively to add comfort level, and a part of student is reluctant to wear.

3, the combined lens that also has, the actual conditions of disengaging eye, two lens parameters is the same or the convex lens number of degrees are all the same, not at different people, different and same individual two different concrete conditions of eye, thereby unreasonable, influence result of use.

4, on array mode, patent applied for the up and down glasses of two halves sheet combination are arranged, but its second sheet has only been used convex lens, does not contain prism, easily cause the eyes set with regulate inharmonious.

Summary of the invention

The purpose of this utility model is for improving deficiency of the prior art, a kind of novel optical control spectacles being provided.

The concrete technical scheme that adopts is as follows:

The utility model comprises a full frame mirror holder and eyeglass, and eyeglass is made of first sheet and the butt joint of second sheet two and half sheets.First sheet uses the myoporthosis sheet, and second sheet uses the lens type compound lens.The concave lens of first sheet is a concace mirror lens, and second sheet is that prism and spherical mirror combine, and is promptly combined by the inside prism of lower degree convex lens additional substrate.The number of degrees of spherical mirror are in+5.00D the scope to-5.00D, the number of degrees of prism by interpupillary distance, eye position, custom with eye distance from determining that with adaptive faculty scope is between 2 Δs-5 Δ.Sheet handing-over line is set in 1-2mm place on horizontal central line or the horizontal central line as required up and down.

The utility model has the advantages that: the utility model with near-sighted correction mirror be last slice, the inside prism of lower degree convex lens additional substrate is sheet down, sheet is combined on one pair of glasses up and down; Consider the student simultaneously actual with eye distance from, the diopter of these glasses is made certain compensation, reaching the patient can see clearly at a distance by myopia correction, can alleviate adjusting and the set seen when near again, and make adjusting and set be in the duty of relatively coordinating, and reach the generation and the development of pre-myopia prevention, can also carry out mist far away and look treatment, pseudo-myopia is recovered, and effect is obvious.Played the good action of a mirror three usefulness very easily.

The utility model processing flexibly, and is easy to use, is a kind of practicality and teenager's anti-myopia glasses of being easy to promote.

Fig. 3 schematic diagram that is the people when first sheet is looked in the distance.

To be the people see schematic diagram when near from second sheet to Fig. 4.

Among the figure: 1 mirror holder, 2 first sheets, 3 second sheets, 4 handing-over lines, 5 lower degree convex lenses, 6 prisms.

Embodiment

Below in conjunction with drawings and Examples the utility model is further described.

See figures.1.and.2, the control spectacles that the utility model provides comprise full frame mirror holder 1 and two eyeglasses up and down, first sheet 2 uses the myoporthosis sheet, second sheet 3 uses the lens type compound lens, two and half sheets butt joint up and down, can adjust down significantly according to the parameter of eyes and add luminosity, the photocentre of first sheet 2 is the 4-5mm place on mirror circle horizontal center line, and the photocentre of second sheet 3 is the 2-4mm place under mirror circle horizontal center line.

Fig. 3 has shown first sheet 2 principle of looking in the distance.The diopter of first sheet 2 of the utility model is by near-sighted optometry design, uses when looking in the distance.As inconvenient mydriasis and contain more the reduced 0.25D of pseudo-myopia one 0.5D design, to avoid frequently changing eyeglass.

Second sheet 3 of the utility model is the inside prisms of lower degree convex lens additional substrate, human eye is in the position at the concave surface place of second sheet 3 among Fig. 2 during use, use during for treatment or prevention, its concave-sphere partly be with eye distance from inverse and the algebraic sum of the near-sighted number of degrees, about two respectively the measuring and calculating, and necessarily accomplish binocular balance, two watch that the comfort distance farthest of clear near vision test type 0.8 delegation's sighting target will equate, makes suitable adjustment to the theoretical number of degrees in view of the above when promptly trying on.

Fig. 4 behaves and to see optical schematic diagram when near, and as can be seen from Figure, convex lens 5 play and make eye reduce an effect of regulating, and prism 6 plays an effect that makes eye reduce set, combines eyes to be in regulate and the harmony state of group.Got rid of the reason that produces myopia.

The prism number of degrees of second sheet 3 of the utility model can reduce by a relatively large margin for keeping comfortable wearing, because of eye uses when the secured adjusted ability of set bigger separately, so looking after adjusting and set universal time coordinated mutually, to keep the comfort level of eye especially to glasses, with overcome current comparatively general serve as to reduce set, and reduce the comfort level of prism, cause some people to be reluctant the shortcoming used.Prism degree is advisable with 2 Δs-5 Δ.
