Description
Technical field
The utility model relates to a kind of double-deck prevention and control myopia Multi-purpose spectacles that can prevent and control myopic degree.
Background technology
Myopia belongs to common a kind of ophthalmology disease, and in recent years, the morbidity crowd of myopia becomes younger quite serious, and this is due to due to the use eyes of transition or incorrect use eyes.Myopia is divided into pseudo-myopia and true myopia, and pseudo-myopia generally can be cured as long as seek medical advice in time; But true myopia generally takes to join mirror control, and general way is exactly the myopic degree according to eyes, is equipped with suitable spectacles.Spectacles see that thing far away is proper, and still, when wearing near-sighted glasses and seeing nearer word or pattern, eyes will not felt well, and this is a more painful thing for the teenager who is going to school.Therefore, people invent a kind of Two-layer spectacle, and this Two-layer spectacle, except normal near-sighted glasses, also adds protective glass in the eyeglass outside of near-sighted glasses again, loads onto after this protective glass, be suitable for seeing nearer word or pattern, and the eyes of not hindering user.This class glasses that all belong to as disclosed in Chinese patent ZL99211391, ZL2007201412216, ZL2010201605390, ZL 2010201605367 and ZL 2010201605526.Because protective glass often will be combined with main near-sighted glasses or separated, this just need to have good combination and isolating construction to realize, Chinese patent ZL 2010201605526 discloses a kind of method of utilizing magnetic to connect, it is exactly that two magnetic patch are set on the bridge of the nose of main spectacles, in the relevant position of protective glass, also establish two magnetic patch, the polarity of two magnetic patch on the bridge of the nose is contrary with the polarity of two magnetic patch on protective glass, when the magnetic patch on protective glass approaches two magnetic patch on the bridge of the nose, both inhale and combination mutually, while needing separation, with the suction that external force overcomes both separation that begins.This structure has good combinableness and separability, and still, this structure has mobility in direction all around at it, causes protective glass always to change with position relationships main near-sighted glasses, unfavorable to protection user's eyes.
Utility model content
In order to overcome the problems referred to above; the utility model provides a kind of main near-sighted glasses and protective glass can facilitate combination or separated to society; simultaneously; when protective glass is when main near-sighted glasses are combined, the double-deck prevention and control myopia Multi-purpose spectacles that protective glass substantially can not move up in the side all around of main near-sighted glasses or swing.
The technical solution of the utility model is: a kind of double-deck prevention and control myopia Multi-purpose spectacles is provided, comprise the main glasses holder of being furnished with concave lens and can be combined with main glasses holder or separated protective glasses by web member, described web member is connected with the magnet of protective glasses relative position by being arranged at main glasses holder, and the magnet on main glasses holder is contrary with the magnet polarity on protective glasses, magnet on described main glasses holder is located on the bridge of the nose, the magnet of described protective glasses is located on web member, between described web member and the described bridge of the nose, be provided with the detent mechanism for preventing that described protective glasses from moving or swinging with respect to main glasses holder all around.
As to improvement of the present utility model, described detent mechanism comprises the inserted sheet being arranged on described web member, and be arranged on the jack on the bridge of the nose, when described protective glasses is when main glasses holder is combined, described inserted sheet is inserted in described jack, limits described protective glasses and all around moves or swing with respect to main glasses holder.
As to improvement of the present utility model, described detent mechanism is arranged on the lower plane that magnet on web member protrudes from web member downwards, being arranged on magnet on the described bridge of the nose caves in and forms a blind hole, when described protective glasses is when main glasses holder is combined, described magnet is inserted in described blind hole, limits described protective glasses and all around moves or swing with respect to main glasses holder.
As to improvement of the present utility model, the xsect of the magnet on the magnet of described protective glasses and/or described main glasses holder is circular, square, triangle or many prismatics.
As to improvement of the present utility model, the eyeglass of described protective glasses is composited by lower degree convex lens and the inside prism of substrate, and the number of degrees of wherein said lower degree convex lens are+convex lens of 1D+2.5D, described prism is the prism of 1 △ 3.5 △.
As to improvement of the present utility model, the eyeglass of described protective glasses is the PC eyeglass made from PC material.
As to improvement of the present utility model, described main glasses holder is made of plastics.
As to improvement of the present utility model, the mirror leg of described main glasses holder is to make with the plastics with memory function.
The utility model is owing to having adopted detent mechanism, and it can prevent that described protective glasses from moving or swinging with respect to main glasses holder effectively all around.In addition, the eyeglass of the described protective glasses in the utility model is made with PC material, and it has advantages of that eyeglass is thin, lightweight, it is broken and safe and reliable to be difficult for.
