Abstract

The utility model relates to a pair of eyeglasses with a myopia correction function. The eyeglass mainly divides an eyeglasses eyeglass area into a light transmission around looking location and a non-light transmission looking location clad in the light transmission around looking location, wherein, the direct looking location is arranged in the symmetrical location of the eyeglass and a eyeball pupil, and one or more one punch hole(s) is (are) arranged in the direct looking location, thus the eyeball pupil can accurately look through the punch hole of the direct looking location, except for a better focus obtained by generating the correction of ocular muscles normal shrinkage, the cautionary attention of the eyeglass to the outside environment and the space of the direct looking location is not influenced, and the utility model is in favor of providing a pair of safe and quick myopia correction eyeglasses without a visual dead angle for a eyeglasses-wearer.

Description

The eyeglass of tool myopia correction function

Technical field

The utility model provides a kind of eyeglass of tool myopia correction function.

Background technology

Myopia is a kind of very general disease.The topmost symptom of myopia is that long distance vision is unclear, main cause is due to the abnormal growth of axis oculi, so claim axial myopia, also claim " true myopia ", every increase by one diopter (1D), axis oculi can increase by 0.37 millimeter, and the number of degrees are high more, increases many more, cause the wall of eyeball attenuation at last, the generation of PVR etc., the therefore prevention of current myopia should be that the abnormal axis oculi of this kind of inhibition how increases, methods of treatment then is to reduce back original axial length, be only basic solution, but the operation that will allow axis oculi shorten involves sclera, nethike embrane is very accurate tissues such as optic nerve, careless slightlyly can have influence on vision on the contrary, do to correct come not as good as wearing glasses at that time safety, so today, all myopias all were to change, reach the purpose of improving eyesight on eyeball leading portion cornea.

No. 85204074 patent in Taiwan discloses a kind of eyeglass of myopia correction function, and it mainly utilizes two opaque filters (being shadow shield), is provided with the plural small sircle hole that one " rice " font is arranged in the middle position of this full wafer filter.

Like this, during use, this full wafer filter area of correcting defects of vision almost completely is the mass colour state, and only it utilizes the hole of the plural small sircle hole of its " rice " font arrangement to make pupil accept the parallel rays of incident, therefore, this correcting spectacle lens then produces inconvenience and shortcoming unavoidably when wearing, be that its sight line then only limits to the dead ahead that pupil passes through " rice " shape hole, therefore the wearer can't conveniently act under the limited situation of sight line, and the close application cum correction eyesight of the affairs that must drop everything.

Summary of the invention

The purpose of this utility model is to provide a kind of and can has the myopia correction function concurrently and not hinder the eyeglass that carries out other affairs simultaneously.

The utility model is to realize like this, the eyeglass of tool myopia correction function, eyeglass is divided into light penetrating ring vision area position and light tight direct-view position, wherein look at the position straight and be symmetric setting, and be provided with one or more perforation in this direct-view position at eyeglass and eyeball pupil.

As mentioned above, the eyeglass of tool myopia correction function also can be arranged at eyeglass in the eyeshade, covers the purposes of eyes as vision correction or cover.

Like this, by making having an X-rayed in the perforation of direct-view position of eyeball pupil with accurate, be able to the clear preferably focusing effect except that producing rectification eye muscle normal contraction, and light penetrating ring vision area position can provide the eyeball pupil suitable induction vision especially, helps the rectifiable eyesight of wearer and carries out other affairs simultaneously.
