Abstract
The utility model relates to an optical lens and in particular relates to a bifocal lens with a color-changing film. The optical lens comprises an arc-surface-shaped optical lens and one layer of color-changing film sheet, wherein the color-changing film sheet is adhered to the convex surface layer of the arc surface of the optical lens; the optical lens and the color-changing film sheet are integrally formed and adhered; a presbyopia vision area is arranged near the lower part of the optical lens; a convex edge is arranged at the concave surface layer of the arc surface of the optical lens corresponding to the presbyopia vision area and is connected to the peripheral edge through a smooth gradually changed arc surface; the presbyopia vision area is directly formed by integrated injection moulding of the optical lens. The optical lens is suitable for people with presbyopic vision to wear indoors and outdoors and has a blue light-resistant function.
Description
Technical field
The utility model relates to the optical mirror slip field, relates in particular to the Bifocal lenses of tool color-changing membrane, and the reading that is applied to multiple occasion is used.
Background technology
For solve the older common people because of the eyesight presbyopic but only wish to see simultaneously nearby object and problem at a distance clearly by wearing a pair of glasses, a patent publication No. 202133833U discloses a kind of pair of light polarizing film optical lenses and offers eyesight presbyopic person and wear when carrying out outdoor activities or driving.But, two light polarizing film optical lenses of this patent obviously mainly are adapted at outdoor occasion and use, when indoor scenarios is used, because of indoor light not as outdoor light strong, the light polarizing film of this pair light polarizing film optical lenses can stop more light, thereby be only suitable for the indoor short time and wear, can not wear for a long time.
Yet, based on existing technology, eyesight presbyopic person only sees nearby object and at a distance clearly simultaneously by wearing a pair of glasses, and most time is to wear use in indoor scenarios, also can wear simultaneously use in outdoor occasion once in a while, and this demand there is no at present method and meets.
In addition,, there is stronger blue light ingredient in the electronic product in daily as the screen of computer, mobile phone, TV etc., and also has stronger blue light ingredient in outdoor ambient light; Yet cross strong blue light and can injure eyes.
The utility model content
Therefore, the purpose of this utility model is: propose a kind of can the time meet eyesight presbyopic person when main outdoor activities and minority indoor activity, can see equally object nearby clearly, change again a kind of optical mirror slip of presbyopic glasses and need not to take off one's glasses; And all right filtering part of this optical mirror slip blue light, to reduce the injury to eyes.
The technical solution of the utility model 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 that cambered surface concave surface one deck by optical mirror slip is provided with a convex edge and by smooth gradual change cambered surface, is attached to periphery corresponding to this presbyopic vision area, and this presbyopic vision area is this optical mirror slip integrated injection molding and directly forming.
Further, the shape of described presbyopic vision area is that circle is clipped the residue shape of subregion by line segment.The presbyopic vision area that is designed to this shape meets most user's visual angle, and also is 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 utility model adopts as above technical scheme, and eyesight presbyopic person wears this eyeglass, by the presbyopic vision area, watches nearby object, and by other vision areas, watches at a distance.This optical mirror slip can be worn out of doors, and while wearing out of doors, colour of lens is deepened, and can carry out outdoor activities or drive, and reads newspaper books, the life of very suitable senior people when also can get sun out of doors.In addition, this optical mirror slip also extremely is suitably in indoor wearing, and during indoor wearing, colour of lens shoals, and, even to water white transparency, can read publication and use computer, and dealing with daily routines.In addition, this optical mirror slip also has filtering part blue light function, can reduce the injury of blue light to eyes.
Description of drawings
Fig. 1 is the front elevation of the optical mirror slip of an embodiment of the present utility model;
Fig. 2 is the sectional view of this embodiment along the A-A line.
Fig. 3 is the partial enlarged drawing of the B section of Fig. 2.
Embodiment
Now with embodiment, the utility model is further illustrated by reference to the accompanying drawings.
Consult Fig. 1, Fig. 2 and shown in Figure 3, the optical mirror slip shown in this embodiment comprises: 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 Fig. 2 and shown in Figure 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 both firm laminatings.The position of described optical mirror slip 1 close below is provided with a presbyopic vision area 101(and consults shown in Figure 1).Corresponding to this presbyopic vision area 101 be cambered surface concave surface one deck by optical mirror slip 1 be provided with a convex edge 1011 and by smooth gradual change cambered surface 1012, be attached to peripheral 1013(consult Fig. 2 and shown in Figure 3), and this presbyopic vision area is this optical mirror slip integrated injection molding and directly forming.
Preferably, the shape of described presbyopic vision area 101 is that circle is clipped the residue shape of subregion by line segment.The presbyopic vision area that is designed to this shape meets most user's visual angle, and also is 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, so that the optical mirror slip of this embodiment can be crossed a part of blue light of filtering, thereby reduction is to the injury of eyes.Concrete, optical mirror slip 1 can add anti-blue light material when light-transmissive resin material integrated injection molding, make eyeglass obtain the effect of anti-blue light.
Optical mirror slip of the present utility model has the large-scale zero diopter vision area of common eyeglass and the presbyopic vision area of presbyopic glasses, and the presbyopic vision area arranges the position of eyeglass near below, the visual angle while being fit to observe nearby.And optical mirror slip of the present utility model can change according to the strong and weak situation of light the shade of eyeglass, thereby is fit to the use of wearing under indoor and outdoor different occasions; And has an anti-blue light function.
Although in conjunction with preferred embodiment, specifically show and introduced the utility model; but the those skilled in the art should be understood that; within not breaking away from the spirit and scope of the present utility model that appended claims limits; can make a variety of changes the utility model in the form and details, be protection domain of the present utility model.
