Presbyopia is a physiological sign of physiological aging of a human body, usually manifests as normal far vision, but poor near vision, needs to be corrected by wearing presbyopic glasses with proper degrees, and after people with myopia walk into the aged, when people see far objects, people need to wear the near vision glasses, and when people see near objects, people need to replace the presbyopic glasses, and frequent glasses replacement can cause great inconvenience to life of people.
In view of the fact that the single-focus glasses cannot meet the needs of the crowd for near-looking and far-looking at the same time, various multifocal glasses appear in markets at home and abroad, the progressive multifocal glasses are used as novel glasses, and a plurality of gradually-changed focuses are formed on a single lens at the same time, so that the definition of the wearer in near-looking and far-looking can be guaranteed, the image jump between different refraction can be reduced in principle, the optical defect of image displacement can be avoided, and the comfort of the wearer in the far-near switching process can be improved.
However, the existing progressive multi-focal glasses only ensure that the central macula position of the human eye is imaged clearly in each visual area, and because the human eye is not in a spherical shape with uniform medium distribution, the refractive distribution of the periphery of the human eye is uneven, light rays can be focused before or after passing through a lens and the human eye, and visual fatigue is easily generated by the stimulation of the retina caused by peripheral defocus.
In order to solve the above-mentioned problems, the present invention provides a progressive addition lens 100, which is aimed at providing an eyeglass lens capable of reducing visual fatigue and improving peripheral visual effects, and fig. 1 to 8 are schematic structural diagrams of an embodiment of the progressive addition lens 100 according to the present invention.
Referring to fig. 1 to 2, the present invention proposes a progressive addition lens 100, which includes a far vision zone 1, a near vision zone 2, a transition zone 3, an astigmatic zone 4, and a refractive compensation zone, wherein the far vision zone 1 is disposed in an area above the progressive addition lens 100 for viewing distant objects, the near vision zone 2 is disposed in an area below the progressive addition lens 100 for viewing near objects, the transition zone 3 is disposed between the far vision zone 1 and the near vision zone 2 for viewing intermediate distance objects, the astigmatic zone 4 is disposed on two sides of the transition zone 3 and is not used for viewing objects, and the refractive compensation zone includes a far vision refractive compensation zone 11 and a near refractive compensation zone 21, which are disposed in the far vision zone 1 and the near vision zone 2, and the refractive compensation zone is used for correcting refractive errors of the periphery of a retina 81 when the human eye is near and far vision.
In the technical scheme of the invention, a far vision refractive compensation area 11 and a near vision refractive compensation area 21 are respectively added in a far vision area 1 and a near vision area 2 of a lens according to the detected distribution data of the peripheral refraction of human eyes so as to correct the peripheral refraction error of the retina 81 of the human eyes, reduce the stimulus of the peripheral defocus of the human eyes to the retina 81, reduce the visual fatigue and improve the peripheral vision capability.
In order to make the refractive compensation zone on the spectacle lens, in an embodiment of the present invention, please refer to fig. 1, the distance vision refractive compensation zone 11 and the near vision refractive compensation zone 21 are configured as two arc-shaped areas with the opening direction towards the center point 5 of the progressive multi-focal lens, and due to the refractive error of the periphery of the retina 81 of the human eye, the distance vision refractive compensation zone 11 and the near vision refractive compensation zone 21 are configured as arc-shaped areas, which are more beneficial to compensate the refractive error of the periphery of the retina 81 when the far and near objects are viewed through the spectacle lens.
Further, since the refractive error degree of each eye is different, when a lens is specifically manufactured, a user needs to perform an optometry to determine the refractive error, specific parameters of the far-vision refractive compensation zone 11 and the near-vision refractive compensation zone 21 of the progressive addition lens 100 to be manufactured are determined according to the actual detection result, please refer to fig. 3 and 4, wherein fig. 3 and 4 are actually measured refractive distribution diagrams within the peripheral field angle of the human eye, wherein an arc Φ 1 enclosed by a dashed line in fig. 3 is the refractive distribution of the far-vision refractive compensation zone 11, an arc Φ 2 enclosed by a dashed line in fig. 4 is the refractive distribution of the near-vision refractive compensation zone 21, the parameters required for the far-vision refractive compensation zone 11 and the near-vision refractive compensation zone 21 are determined by the refractive distribution in the actual field of each user, the corresponding refraction compensation area is processed and manufactured on the progressive multi-focus lens 100, so that the lens formulated by the user can be more suitable for the use condition of the user, after a large number of refraction checks and lens matching are carried out on the user, the design schemes of the distance vision refraction compensation area 11 and the near vision refraction compensation area 21 suitable for most users are summarized, please refer to fig. 2, the lens matching cross 6 is used for observing and judging whether the pupil distance and the pupil height are accurately measured when lens matching is equivalent to an observation standard, the invisible mark 7 can help to restore the mark on the progressive multi-focus lens 100 and wipe clean, so that the parameters of the lens such as materials, design patterns, manufacturers, addition degree and the like can be conveniently obtained again, summarizing the angular dimensions of the arc-shaped areas of said distance vision refractive compensation zone 11 and said near vision refractive compensation zone 21, said arc-shaped areas of said distance vision refractive compensation zone 11 subtending an angle phi 1,160°≤Φ1 < 200 DEG with respect to the central point 12 of the distance vision zone; and/or, the angle surrounded by the arc-shaped area of the near refraction compensation area 21 relative to the central point 22 of the near refraction compensation area is phi 2,160°≤Φ2 -200 degrees, if the angle of the refraction compensation area is too small, the peripheral visual angles of the far vision area 1 and the near vision area 2 of the progressive multi-focus lens 100 cannot be covered, and if the angle of the refraction compensation area is too large, the vision definition of the transition area 3 is affected by the refraction compensation area with excessive tail ends.
Since the distance vision refractive compensation zone 11 and the near refractive compensation zone 21 are both disposed around the center point 12 of the distance vision zone and the center point 22 of the near vision zone, the positions of the distance vision refractive compensation zone 11 and the near vision refractive compensation zone 21 are determined by the specific positions of the center point 12 of the distance vision zone and the center point 22 of the near vision zone, and the specific positions of the center point 12 of the distance vision zone and the center point 5 of the progressive addition lens are determined according to the eye habit of the wearer, please refer to fig. 2, in an embodiment of the present invention, the vertical distance between the center point 12 of the distance vision zone and the center point 5 of the progressive addition lens 100 is h 1,h1 =8 mm; and/or the vertical distance between the center point 22 of the near vision zone and the center point 5 of the progressive addition lens is h 2,7mm≤h2 -17 mm.
In addition, since the rotation degree and the pupil distance of the eye are different when looking far and near through the far vision zone 1 and the near vision zone 2, respectively, the pupil distance when looking near is smaller than that when looking far, so the near refraction compensation zone 21 is moved outwards relative to the nose side when designing, please continue to refer to fig. 2, in the embodiment of the invention, the horizontal distance between the center point 22 of the near vision zone of the progressive addition lens 100 and the center point 5 of the progressive addition lens is x, and x is 1 mm.ltoreq.x.ltoreq.3 mm.
The width of the arc-shaped zone of the refraction compensation zone of the progressive addition lens 100 is also required, please refer to fig. 2, in the embodiment of the present invention, the width of the arc-shaped zone of the distance refraction compensation zone 11 is r 1,6mm≤r1 is equal to or less than 14mm; and/or the width of the arc-shaped area of the near refraction compensation area 21 is r 2,6mm≤r2 -14 mm.
With continued reference to fig. 2, in one embodiment of the present invention, references are given to the distance between the central point 12 of the distance vision zone and the central point 22 of the near vision zone for the distance vision zone 11 and the near vision zone 21, respectively, and the horizontal distance from the central line of the arc-shaped area of the distance vision zone 11 to the central point 12 of the distance vision zone is a 1,10mm≤a1 -16 mm; and/or the horizontal distance from the central line of the arc-shaped area of the near refraction compensation area 21 to the central point 22 of the near vision area is a 2,7mm≤a2 -13 mm, and the vertical distance from the central line of the arc-shaped area of the far vision refraction compensation area 11 to the central point 12 of the far vision area is b 1,6mm≤b1 -12 mm; and/or, the vertical distance from the central line of the arc-shaped area of the near refraction compensation area 21 to the central point 22 of the near refraction area is b 2,5mm≤b2 -11 mm.
The progressive addition lens 100 is named as having a plurality of gradually-changed focuses on the lens, the plurality of gradually-changed focuses are realized by processing and grinding free curved surfaces on the inner surface and/or the outer surface of the lens, the inner surface is the side surface of the progressive addition lens 100 close to human eyes, the outer surface is the side surface of the progressive addition lens 100 far away from the human eyes, the curvature radius of the free curved surface on the progressive addition lens 100 is different, the optical power of light is also different, and therefore different imaging effects are achieved, the far vision refractive compensation area 11 and the near vision refractive compensation area 21 can also achieve the effect of performing peripheral compensation of an optical zone by processing free curved surfaces on the surface of the lens, and the free curved surfaces of the far vision refractive compensation area 11 and the near vision refractive compensation area 21 can be arranged on the outer surface and/or the inner surface of the lens, so that the peripheral vision zone can be effectively refractive compensated.
To more intuitively illustrate the effect of adding refractive compensation zones to progressive addition lens 100 on peripheral vision of the human eye in embodiments of the present invention, please refer to fig. 5 to 8, wherein fig. 5 and 6 are schematic diagrams of refraction of a normal progressive lens on the actual human eye 8 during distance viewing and near viewing, respectively, because the eyeball is not regular sphere, although the central macular 82 object image is converged at the retina, peripheral light may converge on the front side or the rear side of retina 81 after passing through the far vision zone 1 and near vision zone 2 due to non-uniform refractive distribution of the peripheral vision of the human eye, which may result in defocus on the periphery of retina 81.
Fig. 7 and 8 are schematic diagrams of refraction of the progressive addition lens 100 based on peripheral refraction compensation when the actual human eye 8 is seen far and near, and the peripheral refraction distribution of the human eye is unevenly compensated by the far vision refraction compensation region 11 and the near vision refraction compensation region 12, respectively, and peripheral light rays are converged on the retina 81 after passing through the far vision region 1 and the near vision region 2, and as the peripheral light rays are not defocused on the peripheral retina 81, the adjustment of peripheral vision is reduced, the visual fatigue of human eyes is reduced to a certain extent, and the peripheral vision capability is improved.
The invention also provides progressive glasses, which comprise a glasses frame and a progressive lens 100, wherein the specific structure of the progressive lens 100 refers to the above embodiments, and as the progressive glasses adopt all the technical schemes of all the embodiments, the progressive glasses have at least all the beneficial effects brought by the technical schemes of the embodiments, and are not repeated herein.
The foregoing description is only of the preferred embodiments of the present invention, and is not intended to limit the scope of the invention, but rather, the equivalent structural changes made by the description of the present invention and the accompanying drawings or the direct/indirect application in other related technical fields are included in the scope of the invention.
