Detailed Description
The present invention will be described in further detail with reference to examples.
Example 1
As shown in fig. 1, a device for performing zoom polar training using a multifocal lens or lens set includes a lens or lens set 100 having a multifocal optical curve, the lens or lens set 100 is mounted on a suitable frame and can be relatively fixed in front of the eyeball of a user, and the user can use the lens or lens set as glasses, but it depends on the implementation of the technical solution described in the present application in order to better implement more convenient, convenient and natural zoom polar training.
Further, the present invention further includes a driving device 200: the driving device 200 is used to drive the lens or the lens group 100 to perform a movement including rotation or movement at a suitable distance in front of the eyeball, but may also be used to perform the rotation or movement at the same time; when the lens or the lens group 100 moves, the driving device 200 controls the movement amplitude of the lens or the lens group 100 to be repeatedly changed within a limit amplitude. The drive means 200 comprises a precision motor or the like, such as a stepper motor, although other similar means may be used. In the present embodiment, the lens or the lens group 100 is controlled and directly driven by an electronic program, but other driving methods, such as a mechanical method, for controlling the lens or the lens group 100 may also be applied. The appropriate distance described in the present application is a general distance that can perform a focusing function of the glasses, and those skilled in the art can know an actual size of the appropriate distance and appropriately adjust the distance according to eyeballs of different people.
The limit amplitude refers to the maximum movement amplitude change of the human eyeball capable of keeping the visual object clear or clearer, and the actual visual definition can be not influenced by zooming in the range by utilizing the range of the compensatory degree of the human eyeball. In order to avoid the influence of the change of the distance of the visual object of the user on the compensation degree range of the eyeball, a compensation range needs to be preset, the driving device can select in the preset compensation range, and a smaller range is selected in the range, so that the definition of the visual object of the user is realized on the basis of ensuring the realization of zoom great training.
The amplitude includes the rate of movement or rotation of the lens or lens set 100, the time of the movement, the distance traveled by a particular portion of the lens or lens set 100. This portion is controlled by the lens or lens set 100 itself or, if a separate control device is installed, by the control device. Regardless of the mechanism, the lens or lens array 100 is capable of achieving a gradual change in the optical focus area in front of the user's eye at certain intervals. The amplitude variation parameter may be selected from the above parameters, or may be combined with other parameters to form a new amplitude variation, and the other parameters are not described in the present embodiment, but within the range that the mechanical mechanism can be realized, a person skilled in the art may combine the above parameters with any of the speed, the movement time, and the distance to be traveled to obtain a new amplitude variation.
As shown in fig. 2 and 3, the frame shown in the figure is the size of the variable focus, rather than the edge of the lens, the lens can be made into a rectangle or a circle according to different rotation modes, further, the embodiment also includes two basic motion modes, but it should be noted that the two basic motion modes can be combined to obtain a new motion mode within the range that the mechanical mechanism can be realized, and those skilled in the art can combine within an optional range after understanding the embodiments described in the present application.
The basic movement patterns include: the lens or the lens group 100 comprises a plurality of optical focus areas 101 along the extension direction of a straight line; the optical focus area 101 refers to an area having a fixed optical focus; the optical focal areas 101 arranged along the extension direction change gradually, in other words, the lens or lens group 100 having the optical focal areas 101 changing gradually forms an area of gradually changing optical focal point, and the following rotational movement is the same.
However, unlike the rotational movement described below, the optical focus area 101 includes a near vision area 101a and a far vision area 101b, which are adjacent to each other, and the change in focus of the optical focus area 101 at the joint portion of the adjacent areas is also gradually changed. After a predetermined distance and time of movement, the lens or lens set 100 will control whether the area in front of the user's eyes is near vision or far vision.
Further, the lens or lens group 100 rotates along a circle center and includes a plurality of optical focus areas 101 in a circumferential direction relative to the circle center; the optical focus area 101 refers to an area having a fixed optical focus; the optical focus areas 101 arranged along the extension direction gradually change.
Further, the center 102 is located at a side portion or a side of the eyeball.
Further, the movement amplitude of the lens or the lens group 100 may be selected from a plurality of preset values, and the selection may be real-time or preset, and specifically, the selection further includes a plurality of movement speed values; different speed values are selected, and the driving device 200 is enabled to adjust the movement speed of the lens or the lens group 100 according to the selected speed values.
Or, further comprising a plurality of movement distance values; selecting different movement distance values, and enabling the driving device 200 to adjust the movement distance per unit time of the lens or the lens group 100 according to the selected movement distance values.
It should be noted that the above-mentioned variations of multiple amplitudes can also be combined with other variation parameters to form new amplitude variations, and those skilled in the art can combine the new amplitude variations based on the knowledge of the present application. For the user, the change of the change range can effectively avoid the problem of the reduction of the training effect caused by the adaptation of eyeball muscles to a specific change rule. Considering the memory of the eye muscles, it is better to determine the number of different amplitudes as 10-20, but it should be noted that other numbers of amplitudes may be applied, too few varying amplitudes will probably affect the training effect, but this also varies from person to person; the amount of variation is limited by the accuracy of the drive device 200.
Further, the lens group comprises at least 2 lenses I which are stacked, move in respective preset directions and cause the change of the optical focus of the lens group. By changing the relative positions of different lenses in the lens group, smoother changes in the optical focus can be obtained, and the overall length of the lens group can be shortened. It should be noted that the accuracy of the lens assembly will be more demanding than a single lens.
Further, the distance measuring device 300 is installed on one side of the lens or the lens group 100; when the distance measuring device 300 measures that the front distance is smaller than the preset value, a signal is sent. The distance measuring device 300 can help a user to maintain a relatively stable object distance, and especially when the head of the user is too changed during reading and writing, the eyeball cannot adapt to the too large change range. In addition, the signal sent by the distance measuring device 300 is fed back to the lens or the lens group 100, so that the variation range of the amplitude of the lens or the lens group 100 can be adjusted, especially when the head of the user shakes a large amplitude, the variation range of the amplitude of the lens or the lens group 100 can be narrowed, and even the movement of the lens or the lens group 100 is stopped, thereby preventing discomfort caused by the large variation range. In addition, the distance measuring device 300 is generally used for a user to view a visual object at a short distance, such as reading or writing, or the like. However, the user does not need to use the distance measuring device when observing the movement such as the movement from a distance or walking.
Further, a preset step is included to select the limit width of the lens or lens set 100 according to the naked eye vision of the user. Before using the above-described device, it is necessary to determine the limit amplitude and automatically assign a plurality of different variation amplitudes in the case of naked-eye vision.
In summary, the above-mentioned embodiments are only preferred embodiments of the present invention, and all equivalent changes and modifications made in the claims of the present invention should be covered by the claims of the present invention.
