Abstract

A present dual-optical lens only has two refraction effects and is not suitable for applications of myopia prevention, treatment and correction for youngsters. The utility model provides a pair of photobiological two-purpose glasses for myopic people, which is mainly composed of a main glasses frame, an additional glasses frame and lenses and is characterized in that the lenses are half-piece or flat-light type distant lenses and close lenses. The utility model has the effects of distant scieropia, visual improvement through taper holes, distant vision correction, close scieropia and load alleviation for positive accommodation and is adequate to applications of myopia prevention, treatment and correction for youngsters.

Description

Myopia physiological optics Dual-purpose glasses

The utility model belongs to normal life health keeping products.

Must correct with concave lens or taper hole vision boost len sheet when juvenile shortsightedness is looked thing far away and improve distant vision, must alleviate with low concave lens when looking nearly thing and look nearly adjusting load, when the juvenile shortsightedness mist is looked therapy, mist apparent time usefulness+3.00D convex lens far away, nearly mist apparent time 1.50D convex lens.Existing Bifocal lenses only has two kinds of dioptric effects, is unsuitable for the prevention, treatment of juvenile shortsightedness and uses when correcting.

The purpose of this utility model provides a kind of myopia physiological optics Dual-purpose glasses, wear this glasses look have that mist far away is looked when far away, taper hole increases and looks and correct the distant vision effect, look and have nearly mist when near and look and alleviate and look nearly adjusting load effect, can be used as prevention, the treatment of juvenile shortsightedness and use when correcting.

Myopia physiological optics Dual-purpose glasses is made up of main glasses holder, additional mirror holder, eyeglass, it is characterized in that eyeglass is that half chip or zero diopter formula far reach the nearly eyeglass of using with eyeglass, far with eyeglass comprise mist visor sheet far away, far with concave lens and taper hole vision boost len sheet, closely comprise nearly mist visor sheet and closely use concave lens with eyeglass, when closely being loaded on primary frame with eyeglass, far be loaded on the additional picture frame with eyeglass; When far being loaded on primary frame with eyeglass, closely be loaded on the additional picture frame with eyeglass, closely with the low 1.00-3.00D of the concave lens ratio refractive diopter with concave lens far away.

Accompanying drawing 1 far and near mist is looked the structural representation of myopia physiological optics Dual-purpose glasses, the nearly mist visor of Fig. 2 half chip sheet is loaded on the structural representation of primary frame, Fig. 3 half chip mist visor far away sheet is loaded on the structural representation of additional mirror frame, the synoptic diagram of the nearly mist visor of Fig. 4 half chip sheet, the synoptic diagram of the nearly mist visor of Fig. 5 zero diopter formula sheet, the synoptic diagram of Fig. 6 half chip mist visor far away sheet, Fig. 7 half chip is far used the synoptic diagram of concave lens, the synoptic diagram of Fig. 8 half chip taper hole vision boost len sheet, Fig. 9 half chip is closely used the synoptic diagram of concave lens.Among the figure: 1 primary frame, 2 main frame legs, 3 additional picture frames, 4 additional picture frame snap rings, 5 nearly mist visor sheets, 6 mist visor sheets far away, 7 plano lenses, 8 far use concave lens, 9 painted lenses, 10 peep-holes, 11 closely use concave lens.

Below in conjunction with accompanying drawing the utility model is further described.

Adopt existing Dual-purpose glasses frame as myopia physiological optics Dual-purpose glasses frame, the example that is embodied as with snap ring-type Dual-purpose glasses frame, employing is shaped on the main glasses holder of primary frame (1) and primary mirror leg (2), selects to be complementary with the primary frame size, is shaped on the additional picture frame (3) of additional picture frame snap ring (4).The eyeglass of myopia physiological optics Dual-purpose glasses can be made into half chip or zero diopter formula far with eyeglass and closely use eyeglass, far with eyeglass comprise mist visor sheet far away, far with concave lens and taper hole vision boost len sheet, closely comprise with eyeglass that nearly mist visor sheet reaches and closely use concave lens.It is half size of picture frame with eyeglass that half chip far reaches near with eyeglass, and half chip far is complementary with eyeglass and picture frame top size, and half chip closely is complementary with eyeglass and picture frame bottom size.The zero diopter formula be that far away to use eyeglass, eyeglass bottom be plano lens with the eyeglass top of eyeglass far; The zero diopter formula be that near to use eyeglass, eyeglass top be plano lens with the eyeglass bottom of eyeglass closely.With the example that is embodied as of half chip and the nearly mist visor of zero diopter formula sheet, the nearly mist visor of half chip sheet (5) usefulness+1.50D convex lens forms (as Fig. 4), and the eyeglass top of the nearly mist visor of zero diopter formula is plano lens (7), and the eyeglass bottom is+1.50D convex lens (as Fig. 5).Half chip mist visor far away sheet (6) usefulness+3.00D convex lens forms (such as Fig. 6).Half chip far uses concave lens (8) to form (as Fig. 7) with concave lens, the refractive diopter of its concave lens is identical with the recessed sphere power number of each wearer's myopia, count difference according to the recessed sphere power of wearer's myopia, far with concave lens can be made into-0.50D is to-specification that 25.00D is different, wear to adapt to different myopes.Form painted lenses (9) with light tight glass, plastic material or frosted glass, on its eyeglass, make the peep-hole (10) of garden shape, polygon, phenyl ring shape, form half chip taper hole vision boost len sheet (as Fig. 8).Half chip closely uses concave lens (11) to form (such as Fig. 9) with concave lens, and the refractive diopter of its concave lens is worn to adapt to different myopes than the low 1.00-3.00D of the refractive diopter with concave lens far away.The nearly mist visor of half chip sheet (5) is loaded on the primary frame (1) (as Fig. 2), half chip mist visor far away sheet (6) is loaded on the additional picture frame (3) (as Fig. 3), will add picture frame snap ring (4) again and be stuck on the primary frame (1) and to form far and near mist and look myopia physiological optics Dual-purpose glasses (as Fig. 1).This glasses can will far be loaded on primary frame or the additional picture frame with eyeglass according to the difference of prevention, treatment and rectification effect, also can nearly be loaded on primary frame or the additional picture frame with eyeglass.When closely being loaded on primary frame with eyeglass, far be loaded on the additional picture frame with eyeglass, when far being loaded on primary frame with eyeglass, closely be loaded on the additional picture frame with eyeglass.Far also can be made into mist far away with eyeglass and look far with concave lens and the mist cone far away hole vision boost len sheet of this glasses, half chip be that the concave lens, eyeglass top used far away is that mist visor sheet far away forms half chip mist far away and looks the concave lens of using far away with the eyeglass bottom of eyeglass far; Half chip is taper hole vision boost len sheet with the eyeglass bottom of eyeglass far, and eyeglass top is that mist visor sheet far away forms the half chip mist cone far away hole vision boost len sheet.

The wearer can be according to the difference of bathomorphic prevention, treatment and rectification effect, and conversion primary mirror and additional mirror style will be far with eyeglasses and closely with the synthetic different dioptric effects of lens set.This glasses nearly mist visor sheet with mist visor sheet far away, far with concave lens and the combination of taper hole vision boost len sheet; Also can be nearly with concave lens with far make up with concave lens.

The inventor utilizes existing Dual-purpose glasses frame, has designed a kind of half chip or zero diopter formula and has far reached the nearly eyeglass of using with eyeglass, forms far away from reaching closely with producing different dioptric effects.This glasses have that mist far away is looked, taper hole increase look, correct distant vision, nearly mist is looked and is alleviated and looks nearly adjusting load effect, can fully satisfy prevention, the treatment of juvenile shortsightedness and correct and use.
