Abstract
Obturator with pinhole is multi-functional soft painted contact lenses with holes, and with producing high-molecular platform thing, the coloured silk ring (1) (3) that the inside accompanies painted (grey, blue look, comprehensive look and black) is made oblate cylindricality blank (2), grinds through turning and makes.
The diameter of color ring is 7～8mm; Radius-of-curvature is 7.8～8.1mm; The diameter of center hole is 0.5～1.0mm; Thickness is 0.05mm; Book and light tight.The diameter of obturator with pinhole (5) is 13～14mm; The radius-of-curvature of negative camber is 7.8～8.1mm; The diameter of center hole is 0.5～1.0mm (4).Have treatment pseudo-myopia, treatment amblyopia, correct various astigmatism and ametropia, rectification aphakia, white youngster's illness in eye and shooter and wear usefulness.
Description
The present invention relates to vision protection, improve hyperopia and myopia, prevent and treat multi-functional contact lenses such as myopia and treatment amblyopia.
Contact lenses have another name called contact lenses, and the T﹠B that comes out improves through development constantly, it is raw material that the seventies begins to use macromolecular compound-hydroxyethyl methacrylate second fat, make the water wettability soft contact lenses, by the countries in the world widespread use, rather well received.
According to the interrelated data record, the incidence of disease of countries in the world juvenile shortsightedness is very high, and wherein pseudo-myopia accounts for the overwhelming majority.The incidence of disease of amblyopia is also considerable, has caused widely to pay attention to.For this reason, should carry out preventing and controlling energetically, to guarantee children and teen-age good vision.
The new product that the purpose of this invention is to provide a kind of multi-functional contact lenses is because it has shading, increases and look and see the nearly few effect that maybe need not regulate of using.So obturator with pinhole has unique effect, 2. treat amblyopia as 1. treating pseudo-myopia, the amblyopia eye is worn with zero diopter or the obturator with pinhole of the number of degrees is arranged, double excitations, improve eyesight, NAE is then worn the dark-grey or black eyeglass with atresia, suppresses its visual acuity and 3. corrects various astigmatism and ametropia, and the elderly wears usefulness, see and far see the closely all clear aphakia of 4. correcting, see closely also clear 5. white youngster's illness in eye, shading improve again eyesight 6. the shooter wear usefulness, to improve the hit rate level.
The object of the present invention is achieved like this: accompany the oblate cylindricality blank of the hydroxyethyl methacrylate second fat of a color ring in the middle of at first making, be made with the turning grinding technics.Color ring is to make with painted organic glass or other book membrane materials, and color has grey, blue look, combines look and black etc., selects for use for different ethnic groups.The diameter of color ring is 7～8mm; Radius-of-curvature is 7.8～8.1mm; The diameter of center hole is 0.5～1.0mm; Thickness is 0.05mm, book and light tight.The diameter of blank is 16mm; Thickness is 6mm, is oblate cylindricality.
This eyeglass can be as required, with blank be processed into various diameters (13～14mm), various radius-of-curvature (7.8～8.1mm), the soft water wettability obturator with pinhole of all thickness and the various number of degrees, the diameter of center pit is 0.5～1.0mm, and the number of degrees are presented in the center pit.
Other has additional eyeglass, is called stealthy coloured mirror, and its color ring is light tight or semi-transparent painted (grey, blue look, comprehensive look and black etc.) book sheet not with holes, during the treatment amblyopia, for NAE is worn usefulness.Also can be used for beauty treatment.Using method is identical with common contact lenses with points for attention.
Structure of the present invention, pointed out by Figure of description: Fig. 1 is the front figure of the blank of obturator with pinhole, comprise color ring (1) and oblate blank material (2), Fig. 2 is the front figure of obturator with pinhole, comprise color ring (3), the diameter of its center pit is 0.5～1.0mm(4) and the transparent material (5) of eyeglass, and Fig. 3 is the front figure of stealthy coloured mirror, comprises the colored disk (6) not with holes and the transparent material (7) of eyeglass.
Claims (2)
1, a kind of obturator with pinhole is a stock with hydroxyethyl methacrylate second fat, and lighttight color ring of therebetween is made, and it is characterized in that color ring central hole diameter is 0.5～1.0mm, and printing opacity also has certain diopter; Whole stealthy mirror diameter is 13～14mm, and the negative camber radius-of-curvature is 7.8～8.1mm.
2, according to claim 1 obturator with pinhole, it is characterized in that color ring can have certain color, external diameter is 7～8mm, radius-of-curvature is 7.8～8.1mm.
