The embodiment of the utility model provides a self-adaptation vision lens, it is shown with reference to fig. 1, this self-adaptation vision lens includes: a transparent substrate 10 and a plurality of microlenses 20. Wherein, each microlens 20 corresponds to a focal length, and each microlens 20 comprises a plurality of microlenses 20 with the same focal length; the transparent substrate 10 is a planar substrate, and a plurality of microlenses 20 are disposed on at least one side of the transparent substrate 10. Here, the microlens 20 refers to a lens having a small size, and for example, a lens having a size (e.g., a diameter, etc.) smaller than a preset threshold (e.g., 10mm) may be referred to as a microlens.

In the embodiment of the present invention, a plurality of microlenses 20 are disposed on at least one side of the transparent substrate 10 to form a lens capable of adaptive vision. The transparent substrate 10 is a substrate transparent to at least visible light, and may be specifically made of glass, silicon oxide, or the like; alternatively, the transparent substrate 10 and the microlenses 20 may be integrally formed, and the materials of the two are the same. In this embodiment, the transparent substrate 10 is a planar substrate, so as to facilitate the fabrication of the microlens 20; moreover, the shape of the transparent substrate 10 is the shape of the adaptive vision lens, which may be circular, square, etc., or, since the adaptive vision lens provided by this embodiment can be directly used for making glasses without the processes of glaring, polishing, etc., the shape of the transparent substrate 10 may also be matched with the frame of the glasses.

In the embodiment of the present invention, the microlenses 20 are divided into a plurality of types, and each type of microlens 20 corresponds to one focal length; since the power of the glasses is equal to the reciprocal of its focal length (in meters) multiplied by 100, i.e. there is a one-to-one correspondence between the focal length and the lens power, each type of microlens 20 also corresponds to one power. Wherein it can be determined which focal lengths of the microlenses 20 are required based on the current requirements. For example, if the adaptive vision lens requires 100, 200 and 300 degree microlenses 20, three types of microlenses 20 are required, each microlens 20 having a focal length of 1000mm, 500mm, 250mm in that order. Optionally, the reciprocal of the focal length (e.g., power, diopter) of the various microlenses 20 are in an arithmetic series. When the adaptive vision lens is a far-vision lens, the micro lens 20 is a convex lens, the focal length of the convex lens is a positive value, and the power of the convex lens is a positive value; when the adaptive vision lens is a near vision lens, the micro lens 20 is a concave lens, and the focal length and the power of the concave lens are negative values.

The adaptive vision lens utilizes a plurality of microlenses 20 of different degrees to achieve adaptive vision. Specifically, each microlens 20 needs to include a plurality of microlenses 20, that is, the number of microlenses 20 in each microlens 20 is plural, and all microlenses 20 are disposed on one side of the transparent substrate 10. For example, the microlenses 20 do not overlap with each other.

The embodiment of the utility model provides a self-adaptation vision lens, its microlens 20 of having laid multiple different focuses can realize different correction effects to the light that sees through this self-adaptation vision lens, and when the user used this self-adaptation vision lens, the brain that utilizes the user brain mends ability and vision and stops the effect, and user's eyes can seek clear position automatically to the user of different degrees all can see things before the eye clearly through this self-adaptation vision lens. The self-adaptive vision lens does not need processes of optometry, lens customization and the like, can meet the requirements of people with different degrees (including myopia and hyperopia), and has universality; moreover, the micro lens 20 is arranged on the planar transparent substrate 10, so that the processing is convenient, the processing cost can be reduced, and the mass production is realized.

Alternatively, the microlens 20 is a spherical lens, or an aspherical free-form surface lens. Taking the microlens 20 as a convex lens as an example, as shown in fig. 2, the microlens 20 can be a hemisphere or a spherical cap with a radius R; alternatively, as shown in fig. 3, the microlens 20 may be a free-form surface lens having a specific radius of curvature.

For example, if the microlens 20 is a spherical lens, the radius R of the microlens 20 can be determined based on the focal length of the microlens 20:

where n represents the refractive index of the microlens 20 and D represents the power of the microlens 20.

If the microlens 20 is a free-form surface lens, the surface vector z of the microlens 20 satisfies the following formula (2), and the focal length f of the microlens 20 can be determined.

Wherein c is the curvature of the central point (1/R), R is the numerical value of the free-form surface lens along the radius direction, k is a quadric constant, and A-J respectively correspond to high-order coefficients.

In this embodiment, a plurality of microlenses 20 are periodically arranged on at least one side of the transparent substrate 10 to form a microlens array. The arrangement period of the microlenses 20 can be between 50 μm and 5mm, i.e., the diameter of the microlenses 20 is between 50 μm and 5 mm. If the outer shape of the microlens 20 is a square or a hexagon, the diameter of the microlens 20 refers to the diameter of the circumscribed circle of the microlens 20.

Optionally, in order to improve the vision correction effect of the adaptive vision lens, a plurality of microlenses 20 are disposed in a close-packed fashion on at least one side of the transparent substrate 10. For example, the bottom surface of the microlens 20 may have a square or hexagonal shape to enable a close-packed arrangement. When the microlenses 20 are closely arranged, the microlenses 20 and the transparent substrate 10 may be integrally formed as a single body.

Optionally, the material of the micro-lenses 20 is optical plastic, so as to facilitate the processing of the plurality of micro-lenses 20; the refractive index of the micro lens 20 is between 1.4 and 1.8. Taking the microlens 20 and the transparent substrate 10 as an integral structure, referring to fig. 4, an injection molding process can be used to obtain the adaptive vision lens 1 including a plurality of microlenses 20. The injection molding process may specifically include:

step S1: the metal mold 100 is processed in accordance with the shape of the desired microlens 20, and the metal mold 100 having the shape of the microlens array is produced.

Step S2: molten optical plastic 200 is injected between the metal molds 100.

Here, a flat pressing plate 300 may be disposed on the outer side of the molten optical plastic 200 to ensure that one side of the optical plastic 200 is flat.

Step S3: after cooling, the mold is released to form the adaptive vision lens 1 containing the microlens array.

The adaptive vision lens is, for example, a unitary structure in the form of a microlens array that is capable of separating a plurality of different kinds of microlenses 20. Referring to fig. 5, the shape of the microlens 20 is a regular hexagon, and the plurality of microlenses 20 can be arranged in a close-packed manner. Fig. 5 shows a top view of the microlens array in the lower left part, and fig. 5 shows an axial view of the microlens array in the lower right part. Alternatively, referring to fig. 6, the microlens 20 has a square shape, and a plurality of microlenses 20 can be arranged in a close-packed manner. Fig. 6 shows a top view of the microlens array in the lower left part, and fig. 6 shows an axial view of the microlens array in the lower right part.

Alternatively, the plurality of kinds of microlenses 20 may be randomly arranged on at least one side of the transparent substrate 10. As shown in fig. 5 and 6, each of the microlenses 20 is disposed in a randomly distributed manner on one side of the transparent substrate 10. In fig. 5 and 6, the numbers (r), (c), and (c) respectively denote a kind of microlens 20, that is, all microlenses (r) have one focal length, all microlenses (c) have another focal length … …, and so on.

Alternatively, the random distribution includes an equiprobable random distribution having the focal length of the microlens 20 as a random variable. That is, the probability of which microlens 20 is selected is the same at any position of the adaptive vision lens. For example, each of the microlenses 20 includes the same number of microlenses 20, and all of the microlenses 20 are randomly distributed on one side of the transparent substrate 10. For example, if the adaptive vision lens requires 10 kinds of microlenses 20 with different focal lengths, and the total number of microlenses 20 is 1000, 100 microlenses 20 can be selected for each type, and the adaptive vision lens is generated by arranging them in a random arrangement.

Alternatively, the random distribution comprises: the unequal probability random distribution having the focal length or power of the microlens 20 as a random variable is a convex random distribution.

In the embodiment of the present invention, the distribution probability of the different kinds of microlenses 20 is different, for example, the number of the different kinds of microlenses 20 may be different. The embodiment of the utility model provides a self-adaptation vision lens can be applicable to the user in the certain degree scope and use, and the concrete numerical value of this degree scope is relevant with the focus of the microlens 20 that self-adaptation vision lens chooseed for use, and when the user chooseed for use the self-adaptation vision lens of different degrees scopes, chooseed for use the median and self degree assorted self-adaptation vision lens of this degree scope more easily. For example, the power range of the adaptive vision lens is 200 degrees to 400 degrees, the adaptive vision lens is more easily selected by users with the power of 300 degrees. In order to improve the effect of correcting the user's eyesight, the non-equal probability random distribution according to which the microlenses 20 are arranged is a convex random distribution having a high center and low sides, that is, a higher probability of the center focal length or power. For example, the unequal probability random distribution may be a gaussian distribution, a poisson distribution, or the like.

The random variable of the non-equal probability random distribution may be a focal length or a power, and the non-equal probability random distribution of all the microlenses 20 can be generally realized by using the power as the random variable.

As shown in fig. 5 and 6, numbers of (r) to (r) represent 10 kinds of microlenses 20 of different powers (different focal lengths), respectively, the kind of microlens 20 at each position can be determined, and then the adaptive vision lens is designed and manufactured. Taking the example shown in fig. 6 as an example, for microlens 20 at the upper left corner, the probability of which microlens 20 in (r) to (r) is selected conforms to the probability distribution function; for example, if the random distribution is equal probability random distribution, the probability of which microlens is selected at the upper left corner position is the same; if the random distribution is non-equal probability random distribution, the probability that the microlens 20 with the middle focal length or the middle power is selected at the upper left corner is higher. Fig. 6 illustrates the microlens 20 at the upper left corner as a microlens.

The embodiment of the utility model provides a self-adaptation vision lens, its microlens 20 of having laid multiple different focuses can realize different correction effects to the light that sees through this self-adaptation vision lens, and when the user used this self-adaptation vision lens, the brain that utilizes the user brain mends ability and vision and stops the effect, and user's eyes can seek clear position automatically to the user of different degrees all can see things before the eye clearly through this self-adaptation vision lens. The self-adaptive vision lens does not need processes of optometry, lens customization and the like, can meet the requirements of people with different degrees (including myopia and hyperopia), and has universality; moreover, the micro lens 20 is arranged on the planar transparent substrate 10, so that the processing is convenient, the processing cost can be reduced, and the mass production is realized. The microlenses 20 are square or hexagonal in shape, and can be uniform in size, facilitating close packing arrangement. All the micro lenses 20 are distributed in a random distribution mode, so that the clear positions can be found by human eyes automatically, and the method is more suitable for people with different degrees.
