Abstract
The invention relates to an optical lens, in particular to a bifocal lens with a color shift film. The optical lens comprises an optical lens body with an arc-surface shape and a layer of color shift film, wherein the color shift film is attached to the arc convex surface of the optical lens body; the optical lens body and the color shift film are integrally formed; a presbyopia visual region is arranged at a position, which is close to the lower side, of the optical lens; a flange corresponding to the presbyopia visual region is arranged on the arc concave surface of the optical lens body and is connected to the peripheral edge through a smooth gradually-changed arc surface; meanwhile, the presbyopia visual region is directly formed by performing injection molding on the optical lens body. The optical lens is suitable for being worn by presbyopia people in a room and in the open air, and has a blue ray resisting function.
Description
Technical field
The present invention relates to optical mirror slip field, particularly relate to the Bifocal lenses of tool color-changing membrane, the reading being applied to multiple occasion uses.
Background technology
In order to solve the older common people wish to see object nearby and problem at a distance clearly by means of only wearing a pair of glasses because of eyesight presbyopic simultaneously, a patent publication No. 202133833U discloses a kind of two light polarizing film optical lenses and wears when carrying out outdoor activities or driving to be supplied to eyesight presbyopic person.But, two light polarizing film optical lenses of this patent are obviously mainly adapted at outdoor occasion and use, when indoor scenarios uses, because indoor light is strong not as outdoor light, the light polarizing film of this pair of light polarizing film optical lenses can stop more light, thus the short time being only suitable for indoor wears, and can not wear for a long time.
But, based on existing technology, eyesight presbyopic person sees object nearby and at a distance clearly by means of only wearing a pair of glasses simultaneously, and most time wears use in indoor scenarios, also can wear use in outdoor occasion once in a while simultaneously, and this demand there is no at present method meet.
In addition, the electronic product in daily, there is stronger blue light ingredient in the screen as computer, mobile phone, TV etc., and also there is stronger blue light ingredient in the ambient light of outdoor; But excessively strong blue light can injure eyes.
Summary of the invention
Therefore, the object of the invention is: propose one can time meet eyesight presbyopic person at major outdoor and, during movable and minority indoor activity, object nearby can be seen equally clearly, and change a kind of optical mirror slip of presbyopic glasses without the need to taking off one's glasses again; Further, this optical mirror slip all right filtering part blue light, to reduce the injury to eyes.
Technical scheme of the present invention is:
Optical mirror slip, comprise: the optical mirror slip of an arc surface shape and one deck variable color diaphragm, described variable color diaphragm is sticked at cambered surface convex surface one deck of this optical mirror slip, this optical mirror slip and variable color diaphragm are one-body molded and fit, described optical mirror slip is provided with a presbyopic vision area near the position of below, be be provided with a convex edge by cambered surface concave surface one deck of optical mirror slip and be attached to periphery by smooth gradual change cambered surface corresponding to this presbyopic vision area, and this presbyopic vision area is this optical mirror slip integrated injection molding and is directly formed.
Further, the shape of described presbyopic vision area is that circle is by the residue shape in line segment truncated part region.The presbyopic vision area being designed to this shape meets the visual angle of most user, and is also beneficial to injection molding.
Wherein, described variable color diaphragm is TAC variable color sheet.
Further, described optical mirror slip is the optical mirror slip of anti-blue light.
The present invention adopts as above technical scheme, and eyesight presbyopic person wears this eyeglass, by presbyopic vision area viewing object nearby, and is watched at a distance by other vision areas.This optical mirror slip can be worn out of doors, and when wearing out of doors, colour of lens is deepened, and can carry out outdoor activities or drive, and reads newspaper books, very applicable life elderly while also can getting sun out of doors.In addition, this optical mirror slip is also extremely suitably in indoor and wears, and when indoor are worn, colour of lens shoals, and even to water white transparency, can carry out reading publication and use computer, and dealing with daily routines.In addition, this optical mirror slip also has filtering some blue light function, can reduce the injury of blue light to eyes.
Accompanying drawing explanation
Fig. 1 is the front elevation of the optical mirror slip of one embodiment of the invention;
Fig. 2 is the sectional view of this embodiment along A-A line.
Fig. 3 is the partial enlarged drawing in the B portion of Fig. 2.
Embodiment
Now the present invention is further described with embodiment by reference to the accompanying drawings.
Consult shown in Fig. 1, Fig. 2 and Fig. 3, the optical mirror slip shown in this embodiment, comprising: optical mirror slip 1 and one deck variable color diaphragm of an arc surface shape; Described variable color diaphragm 2 is sticked at cambered surface convex surface one deck (consulting shown in Fig. 2 and Fig. 3) of this optical mirror slip 1, this optical mirror slip 1 and variable color diaphragm 2 are one-body molded and fit, as by variable color diaphragm 2 is positioned mold bottom, then one-body moldedly by plastic injection realize the two firm laminating.Described optical mirror slip 1 is provided with a presbyopic vision area 101 (consulting shown in Fig. 1) near the position of below.Be be provided with a convex edge 1011 by cambered surface concave surface one deck of optical mirror slip 1 and be attached to periphery 1013 (consulting shown in Fig. 2 and Fig. 3) by smooth gradual change cambered surface 1012 corresponding to this presbyopic vision area 101, and this presbyopic vision area is this optical mirror slip integrated injection molding and is directly formed.
Preferably, the shape of described presbyopic vision area 101 is that circle is by the residue shape in line segment truncated part region.The presbyopic vision area being designed to this shape meets the visual angle of most user, and is also beneficial to injection molding.
Wherein, this optical mirror slip 1 can adopt light-transmissive resin material (comprise PC, nylon, acrylic or other can be made into the light-transmitting materials of eyeglass) integrated injection molding.This variable color diaphragm 2 is TAC (Triafol T) variable color sheets.
Preferably, optical mirror slip 1 can adopt the optical mirror slip of anti-blue light to make, and with a part of blue light making the optical mirror slip of this embodiment can cross filtering, thus reduces the injury to eyes.Concrete, optical mirror slip 1 can add anti-blue light material when light-transmissive resin material integrated injection molding, makes eyeglass obtain effect of anti-blue light.
Optical mirror slip of the present invention has the large-scale zero diopter vision area of common eyeglass and the presbyopic vision area of presbyopic glasses, and presbyopic vision area arranges the position of eyeglass near below, is applicable to visual angle when observing nearby.Further, optical mirror slip of the present invention can change the shade of eyeglass according to the strong and weak situation of light, thus wears use under being applicable to indoor and outdoor different occasions; And there is anti-blue light function.
Although specifically show in conjunction with preferred embodiment and describe the present invention; but those skilled in the art should be understood that; not departing from the spirit and scope of the present invention that appended claims limits; can make a variety of changes the present invention in the form and details, be protection scope of the present invention
