Description
Technical Field
The utility model relates to a degree adjusting device of a hard contact lens.
Background
Hard contact lenses generally refer to contact lenses made from hard oxygen permeable materials, which may also be referred to as hard contact lenses or hard intraocular lenses.
Hard contact lenses are made in a manner similar to that of conventional spectacle frames and can be made by machining or molding. Additionally, methods for making hard contact lenses typically include the steps of measuring an ocular parameter of a wearer, designing a hard contact lens having an optical zone based on the ocular parameter, and machining/shaping the contact lens.
In the process of manufacturing hard contact lenses, more or less errors may occur in the above steps, which may cause the problem that the lens power of the lens is not suitable when the lens is tried on by the wearer, and the lens power with the unsuitable power needs to be adjusted to the relevant ocular parameters of the wearer.
Disclosure of Invention
The present invention has been made in view of the above-described conventional circumstances, and an object thereof is to provide a power adjustment device capable of adjusting the power of a hard contact lens to a predetermined degree.
To this end, the present invention provides a power adjustment device for a hard contact lens, the hard contact lens including a front surface in a convex shape and a rear surface opposite to the front surface and in a concave shape, the power adjustment device including a grinding mechanism and a support mechanism arranged in an opposing manner, the grinding mechanism including a pressure measurement unit, a rotatable grinding unit having a grinding surface facing the support mechanism, and a control unit connected to the pressure measurement unit and the grinding unit, the support mechanism including a drive unit and a positioning unit driven by the drive unit to move relative to the grinding unit, one end of the positioning unit facing the grinding unit being formed as a cap in a convex shape matching the shape of the rear surface of the hard contact lens, the pressure measurement unit measuring a contact pressure between the hard contact lens and the grinding unit and transmitting the pressure to the control unit, the control part controls the grinding part to rotate by a preset angle based on the contact pressure.
In the degree adjusting device, the degree adjusting device comprises a positioning part matched with the surface shape of the hard contact lens, and the hard contact lens can be thinned through the matching of the supporting mechanism and the grinding part so as to adjust the degree; the control unit controls the rotation angle of the polishing unit based on the contact pressure between the hard contact lens and the polishing unit fed back from the pressure measurement unit, thereby controlling the thickness reduction of the hard contact lens. Therefore, the degree adjusting device can adjust the degree of the hard contact lens to a preset degree.
In addition, in the manufacturing method according to the present invention, optionally, the driving portion has an angle adjusting unit configured to adjust an included angle between a central axis of the positioning portion and the abrasive surface. Thus, the positioning part can support the hard contact lens at a certain angle when the hard contact lens is in contact with the polishing surface at any posture.
In the manufacturing method according to the present invention, the driving unit may include a rotating unit connected to the angle adjusting unit, and the rotating unit may drive the positioning unit to rotate about a central axis thereof as a rotation axis. Under the condition, the rotating unit can drive the hard contact lens to flexibly rotate through the positioning part, and the possibility that the hard contact lens cannot be uniformly thinned when the hard contact lens is in a specific posture for a long time is reduced.
In the manufacturing method according to the present invention, the angle adjusting means and the rotating means may be adapted to adjust a portion of the hard contact lens provided in the positioning portion, the portion abutting on the polishing surface. In this case, different parts of the hard contact lens can be polished by the abrasive surface through the cooperation of the angle adjusting unit and the rotating unit.
In the production method according to the present invention, the drive unit may drive the positioning unit to move along a predetermined path with respect to the polishing surface. This can reduce the possibility of insufficient polishing due to an improper fit between the polishing surface and the hard contact lens during polishing.
In addition, in the manufacturing method according to the present invention, optionally, an end of the positioning portion away from the abrasive surface is formed as a stem portion having a columnar shape, and the driving portion releasably holds the stem portion. Thus, the positioning portion can be detachably provided to the driving portion.
In addition, in the production method according to the present invention, optionally, the abrasive surface is a flexible abrasive plane. Thereby, it can be used to polish the front surface of a hard contact lens.
In the production method according to the present invention, the pressure measurement unit may calculate the contact pressure based on a deformation amount of the polished surface when the hard contact lens is pressed. Therefore, the pressure measuring part can sensitively calculate the real-time contact pressure based on the micro deformation of the grinding surface.
In the production method according to the present invention, the polishing portion may be rotated without changing a normal direction of the polishing surface. This makes it possible to smoothly bring the hard contact lens into contact with the polishing surface during polishing.
In the manufacturing method according to the present invention, the hard contact lens may be fixed to the positioning portion by an adhesive. This reduces the possibility of the hard contact lens being shaken or dropped off when the hard contact lens is ground.
In addition, in the manufacturing method according to the present invention, optionally, the positioning portion is a heatable member; and/or the pressure measuring part is a pressure sensor. Thus, the hard contact lens can be bonded to the positioning portion by the low-melting-point adhesive, and the low-melting-point adhesive can be melted after the positioning portion is heated. In addition, the pressure sensor can measure the contact pressure.
In addition, in the preparation method according to the present invention, optionally, the preset angle is an integer multiple of a minimum angle, and the minimum angle is 0.1 to 0.19 degrees. This makes it possible to control the degree of rotation of the polishing surface and further control the degree of adjustment of the hard contact lens.
According to the present invention, it is possible to provide a power adjustment device capable of adjusting the power of a hard contact lens to a predetermined degree.

Detailed Description
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, the same components are denoted by the same reference numerals, and redundant description thereof is omitted. The drawings are schematic and the ratio of the dimensions of the components and the shapes of the components may be different from the actual ones.
It is noted that, as used herein, the terms "comprises," "comprising," or any other variation thereof, such that a process, method, system, article, or apparatus that comprises or has a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include or have other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The present invention relates to a power adjustment device, hereinafter simply referred to as a power adjustment device, which is capable of adjusting the power of a hard contact lens to a predetermined degree. In some examples, the hard contact lens may be a corneal contact lens or a scleral contact lens, or the like.
FIG. 1 is a schematic diagram illustrating a hard contact lens 20 according to an example of the present invention. Fig. 2 is a schematic radial cross-section illustrating a hard contact lens 20 according to an example of the present invention.
In some examples, the hard contact lens 20 generally includes an anterior surface 21 that is convex and a posterior surface 22 opposite the anterior surface 21 that is concave (see fig. 2). In some examples, the anterior surface 21 and the posterior surface 22 may have a predetermined curvature, and the cooperation between the anterior surface 21 and the posterior surface 22 may have an effect of correcting ametropia.
In some examples, the hard contact lens 20 may include an optical zone, a transition zone, and a landing zone (not shown) distributed in a generally annular shape from the inside to the outside about the center of the optical axis. For convenience of description, the optical zone is divided into a central optical zone and a peripheral optical zone in the present invention. In some examples, there is no strict demarcation between the central optical zone and the peripheral optical zone. In some examples, thinning different regions of the hard contact lens 20 to different degrees may change the curvature of the anterior surface 21 and the posterior surface 22, thereby enabling adjustment of the degree of the hard contact lens 20.
Fig. 3 is a schematic diagram illustrating the thinning of the peripheral optical zone of a hard contact lens 20 according to an example of the present invention. Fig. 4 is a schematic diagram illustrating the thinning of the central optical zone of a hard contact lens 20 according to an example of the present invention.
Considering that the power change of the central optical zone and the peripheral optical zone has a large influence on the power change of the hard contact lens 20, the present invention will be further described by taking the central optical zone and the peripheral optical zone as an example. In some examples, the thinning of the hard contact lens 20 may not be limited to the central optical zone and the peripheral optical zone illustrated.
For a concave lens, a reduction in the radius of curvature of the front surface 21 as a whole may mean a reduction in the negative luminosity. In this case, the degree of reduction of the peripheral optical zone portion in the front surface 21 is made larger as a whole than the degree of reduction of the central optical zone portion in the front surface 21, whereby the degree of negative power of the hard contact lens 20 can be reduced. Considering that a concave lens is generally thinner in the central optical zone and thicker in the peripheral optical zone, the effect of the same amount of thickness reduction on the central optical zone and the peripheral optical zone is different. The degree of thinning of the region of the front surface 21 corresponding to the central optical zone and the degree of thinning of the region of the front surface 21 corresponding to the peripheral optical zone are therefore to be understood as relative degrees of thinning in the present invention.
Also, for a concave lens, an increase in the radius of curvature of the front surface 21 as a whole may mean an increase in negative luminosity. In this case, the degree of reduction of the peripheral optical zone portion in the front surface 21 is made smaller as a whole than the degree of reduction of the central optical zone portion in the front surface 21, whereby the degree of negative power of the hard contact lens 20 can be increased.
Correspondingly, the power adjustment of the convex lens is opposite to that of the concave lens, and the details are not repeated here.
In some examples, the degree of the hard contact lens 20 may be adjusted by a degree adjustment device according to the present invention.
Fig. 5 is a block diagram showing the structure of the frequency adjustment device 10 according to the example of the present invention. Fig. 6A is a front view showing the power adjustment apparatus 10 according to the example of the present invention polishing the central optical zone of the hard contact lens 20. Fig. 6B is a front view showing the power adjustment apparatus 10 according to the example of the present invention polishing the peripheral optical zone of the hard contact lens 20.
In some examples, the degree adjustment apparatus 10 may include a grinding mechanism 100 and a support mechanism 200 (see fig. 5). The support mechanism 200 may be used to support a hard contact lens 20. The grinding mechanism 100 may be used to thin the hard contact lens 20. In some examples, the grinding mechanism 100 and the support mechanism 200 may be oppositely disposed.
In some examples, grinding mechanism 100 may have a grinding portion 110. The polishing portion 110 faces the support mechanism 200. In some examples, the abrasive portion 110 may have an abrasive surface 111. In some examples, the grinding portion 110 may be rotated to thin the hard contact lens 20.
In some examples, grinding mechanism 100 may include a grinding portion 110, a pressure measurement portion 120, and a control portion 130. The pressure measuring portion 120 may be used to measure the pressure to which the grinding portion 110 is subjected. The control part 130 may be used to control the rotation of the grinding part 110. In some examples, the control portion 130 may be connected to the pressure measurement portion 120 and the grinding portion 110. In some examples, the pressure measuring part 120 may measure a contact pressure between the hard contact lens 20 and the polishing part 110 and transmit the contact pressure to the control part 130, and the control part 130 may control the polishing part 110 to rotate by a preset angle based on the contact pressure. In some examples, the abrasive section 110 may be turned (rotated) without changing the orientation of the abrasive surface 111.
In some examples, the larger the predetermined angle, the longer the grinding time for the hard contact lens 20, the greater the degree of thinning, at the same contact pressure. For example, the degree of the reduction of the preset angle of 1080 degrees is greater than the degree of the reduction of the preset angle of 720 degrees under the same contact pressure. In some examples, the greater the contact pressure, the greater the degree of abrasion of the hard contact lens 20 when the preset angle is the same. Therefore, by controlling the preset angle of rotation of the polishing part 110 based on the contact pressure, a desired polishing reduction amount can be accurately obtained.
In some examples, the preset angle may be an integer multiple of the minimum angle. In some examples, the minimum angle may be 0.1 to 0.19 degrees. In some examples, the minimum angle may be equal to the minimum rotational angle (rotational accuracy) of the grinding portion 110. This makes it possible to control the degree of rotation of the polishing surface 111 and further control the degree of adjustment of the hard contact lens 20.
Referring to fig. 6A, in some examples, the support mechanism 200 can include a positioning portion 210.
In some examples, one end of the positioning part 210 may be formed as a cap 211. In some examples, the shape of the cap 211 may match the shape of the posterior surface 22 of the hard contact lens 20. In some examples, the cap 211 may be convex. In some examples, the positioning portion 210 may be configured with the cap portion 211 facing the grinding portion 110. In some examples, the positioning part 200 may press the hard contact lens 20 against the polishing surface 111 of the polishing part 110 through the cap part 211.
In some examples, the support mechanism 200 may include a positioning portion 210 and a driving portion 220. In some examples, the driving portion 220 may drive the positioning portion 210 to move relative to the grinding portion 110. In some examples, an end of the locator 210 distal from the abrasive surface 111 may be formed as a stem 212 having a cylindrical shape. Drive portion 220 releasably retains handle portion 212. Thus, the positioning part 210 can be detachably provided to the driving part 220.
In the power adjustment device 10 according to the present invention, the support mechanism 200 and the polishing unit 110 can be matched to reduce the thickness of the hard contact lens 20. In addition, the control unit 130 may control the rotation angle of the polishing unit 110 based on the contact pressure between the hard contact lens 20 and the polishing unit 110 fed back by the pressure measurement unit 120, so as to control the thickness reduction degree of the hard contact lens 20. This enables the degree of the hard contact lens 20 to be adjusted to a predetermined degree.
In some examples, the driving part 220 may have an angle adjusting unit. In some examples, the angle adjusting unit may be configured to adjust an included angle between the central axis of the positioning part 210 and the abrasive surface 111. Thus, the positioning part 210 can support the hard contact lens 20 at a certain angle when the hard contact lens 20 is in contact with the polishing surface 111 in any posture. In some examples, the degree adjusting device 10 may be switched between the state shown in fig. 6A and the state shown in fig. 6B by the angle adjusting unit to grind and thin different regions of the optical zone.
In some examples, the driving part 220 may have a rotating unit. In some examples, the rotation unit may be connected to the angle adjustment unit. The rotation unit may drive the positioning part 210 to rotate about its central axis as a rotation axis. In this case, the rotating unit can flexibly rotate the hard contact lens 20 by the positioning part 210, thereby facilitating uniform thinning of the hard contact lens 20.
In some examples, the driving part 220 may include an angle adjusting unit and a rotating unit. In some examples, the angle adjustment unit and the rotation unit cooperate to adjust a position where the hard contact lens 20 provided on the positioning portion 210 abuts on the polishing surface 111. In this case, different portions of the hard contact lens 20 can be ground by the grinding surface 111 by the cooperation of the angle adjusting unit and the rotating unit.
In some examples, the abrasive surface 111 may be an abrasive plane. In some examples, the abrasive surface 111 may be a flexible abrasive plane. Thereby, it can be used to polish the front surface 21 of the hard contact lens 20.
In some examples, the pressure measurement section 120 may calculate the contact pressure based on the deformation amount when the abrasive surface 111 is pressed by the hard contact lens 20. Thus, the pressure measuring unit 120 can calculate the contact pressure in real time sensitively based on the minute deformation of the polishing surface 111. In some examples, pressure measurement 120 may be a pressure sensor.
In some examples, the abrasive portion 110 may rotate in a manner that does not change the normal direction of the abrasive surface 111. This enables the hard contact lens 20 to smoothly come into contact with the polishing surface 111 during polishing.
Fig. 7 is a top view illustrating a predetermined path 300 according to an example of the present invention.
Referring to fig. 7, in some examples, the driving portion 220 may drive the positioning portion 210 to move along the predetermined path 300 relative to the abrasive surface 111. This can reduce the possibility of insufficient polishing due to improper fitting of the polishing surface 111 and the hard contact lens 20 during polishing.
In some examples, the predetermined path 300 may include a first path 301 and a second path 302. In some examples, the first path 301 may be substantially circular. The second path 302 may be substantially circular. In some examples, the radius of the second path 302 may be greater than the periphery of the first path 301.
In some examples, the driving part 220 may drive the positioning part 210 to move along the first path 301 when grinding the annular region near the optical axis of the hard contact lens 20. Correspondingly, when the annular region far away from the optical axis of the hard contact lens 20 is polished, the driving part 220 may drive the positioning part 210 to move along the second path 302. In some examples, when the positioning part 210 is driven by the driving part 220 to move along the first path 301, and the annular region close to the optical axis of the hard contact lens 20 is at different positions of the first path 301, the composition regions of the annular region close to the optical axis of the hard contact lens 20 may be sequentially ground and thinned.
In some examples, the preset path 300 may include a transition path 303. In some examples, after the annular region near the optical axis of the hard contact lens 20 is polished and thinned, the driving portion 220 may drive the positioning portion 210 to pass through the transition path 303 to polish the annular region far from the optical axis of the hard contact lens 20.
Fig. 8 is a schematic diagram showing the hard contact lens 20 according to the example of the present invention bonded to the positioning portion 210.
Referring to fig. 8, in some examples, hard contact lens 20 may be secured to positioning portion 210 by an adhesive. This can reduce the possibility of the hard contact lens 20 shaking or falling off when it is ground.
In some examples, the positioning portion 210 may be a heatable element. Accordingly, the hard contact lens 20 can be bonded to the positioning part 210 by the low-melting-point adhesive, and the low-melting-point adhesive can be melted after the positioning part 210 is heated, so that the hard contact lens 20 is separated from the positioning part 210.
In some examples, the hard contact lens 20 may not be fixedly disposed to the positioning portion 210. In other words, during the thinning process, the hard contact lens 20 is clamped by the positioning part 210 and the grinding part 110. In some examples, the cap 211 of the positioning portion 210 may be made of a material having a lower hardness than the hard contact lens 20. In some examples, a glasses cloth may be disposed between the positioning part 210 and the hard contact lens 20. This can provide an effect of protecting the rear surface 22 of the hard contact lens 20.
While the utility model has been described in detail in connection with the drawings and examples, it is to be understood that the above description is not intended to limit the utility model in any way. Those skilled in the art can make modifications and variations to the present invention as needed without departing from the true spirit and scope of the utility model, and such modifications and variations are within the scope of the utility model.
