Abstract

The utility model discloses glasses which can prevent strong light and correct ametropia. The utility model is characterized in that a transparent hole is arranged in the dark field of glasses lens, the diameter of the hole is 0.2 to 2.0 mm which can be a punched hole on the glasses lens or a local transparent region on color glasses lens; the shape, site, number, and arrangement of the hole can be decided according to requirement and the density value of the dark field is between 0.5 to 3. The ametropic person (presbyopic, nearsighted, farsighted, astigmatic eye, etc.) wears the multifunction sight-correcting sunglasses under strong light can protect eyes and see the wanted and observed object clearly from a small hole, which is very convenient.

Description

Multifunction sight-correcting sunglasses

The utility model relates to a kind of except that the new-type glasses that have correction of refractive errors function (presbyopia, myopia, farsightedness and astigmatic eyes etc.) the order effect simultaneously that protect with anti glare anti static coatings.

Under the situation of working in ametropic people operation in the open air, seashore tourism, the high light, wear sunglasses and cause scenery around not seeing because of not wearing corresponding correcting spectacle lens simultaneously often, observe the object details and need take sunglasses often and change correcting spectacle lens and feel inconvenience deeply.

The design people attempts to make a kind of sunglasses can protect the function that order has correction of refractive errors again by anti glare anti static coatings.

Known pin hole mirror can make ametropia patient's eyesight obviously increase, but opaque dividing plate around the hole, the scenery around the wearer can't observe is so can not use as glasses.Through repeatedly experiment, the inventor finds that the pin hole mirror dividing plate not necessarily will be made up of lighttight material, as long as there is the bigger dark space of density to serve the same role in hole week, and sunglasses comes down to various color filter, its optical density (OD) can be a uniformity on an eyeglass, also can be different different because of the position, the latter usually is that the optical density (OD) on eyeglass top is big, successively decrease to next density, it belongs to the gradual change color filter, the utility model is to make transparent apertures at the bigger position of sunglasses optical density (OD), like this, after ametropic people wears this mirror, eyes irriate not under high light, scenery around can seeing can be seen the details of object again clearly in aperture, very convenient.

The utility model multifunctional sunglasses of correcting defects of vision is characterised in that in the eyeglass dark space that transparent apertures is arranged, and the feature in said hole is:

(1) pore diameter range: 0.2-2.0mm, the aperture is excessive, and image is unintelligible, and the aperture is little, the resolving power height, small objects sees clearly Chu, but also certain limit is arranged, and the aperture is too small, and significant x-ray diffraction phenomenon will take place, and is difficult to imaging.

(2) shape in hole: the hole (as hole, garden, shape hole, ellipse garden, square hole, slot, polygonal hole, irregular shape hole, crack etc.) that comprises different shape.

(3) structure in hole: can be the reach through hole on the eyeglass or be the local clear area (can adopt coating process) on the colored lens.

(4) position in hole: can be at any position of eyeglass.Be advisable with the top at eyeglass, when the glasses wearer looked squarely, aperture was about its upper eyelid position, during scenery, almost was not aware of the existence of aperture around observing.When desire is observed the object details, bow slightly and can in aperture, see image clearly.

(5) number in hole: can be single hole, diplopore or porous.

(6) arrangement in hole: diplopore or the porous formation round that is arranged in rows, (single, double or many rows), span should be less than 1.0mm, be advisable with 2.6mm, link by the lower fine rule of density between the hole, to weaken the sensation that dividing plate is arranged between the hole when observing object, round can solve the difference of individual interpupillary distance and the scope that can broaden one's vision.(also can or make the nose-bridge frame of adjustable length) according to interpupillary distance pore-creating.

In order to make aperture can play the effect of correcting defects of vision, hole Zhou Bixu has the big dark space of optical density (OD), and density is big, and is effective.In order to strengthen effect, Kong Zhouke has bigger dark dizzy of a density, and its diameter should not be less than 5mm, for attractive in appearance, swoons secretly that its density can be gradation type in the dark space, as painted towards periphery gradually light by center (little porose area).

The density value of dark space is between 0.5-3, and density value is pressed and shown that formula calculates:

D＝log (F)/(F _τ)

D: represent density value, F represents the projection light flux,

F _τ: represent the transmitted light flux.

When in aperture, observing the object details, enough brightness need be arranged, when wearing sunglasses, general all under high light shines, so can satisfy this condition.

This type sunglasses is applicable to presbyopia, myopia, farsightedness and astigmatic eyes etc., can correct multiple ametropia in anti glare anti static coatings to some extent.The regulating power of old man's eye weakens, and sees far, sees that nearly strength is different, often must join two pair of glasses or bifocals, if use this novel glasses, by aperture far away, nearly object is all easily seen clearly.

Correct defects of vision that multifunctional sunglasses operation in the open air, geologic prospecting, mountaineering, beach are travelled, all can use under the fishing, high light operation situation, as watch instructions, bulletin board, map, the sample of taking and wear and hang bait etc.

Under the professional instructed, general relevant producer all can produce, and also available existing sunglasses carries out process and remould.

Claims

1, a kind ofly can protect the new-type glasses that order has the correction of refractive errors function again by anti glare anti static coatings, it is characterized by in the dark space of eyeglass has transparent apertures.

2, according to the novel sunglasses of claim 1, the structure of its mesopore can be the reach through hole on the eyeglass or is the local clear area on the colored lens.

3, according to the novel sunglasses of claim 1, wherein the shape in said hole comprises the hole or the crack of different shape.

4, according to the novel sunglasses of claim 1, wherein the aperture is generally 0.2-2mm, preferably 1-1.5mm.
