Description

Out-of-focus lens and glasses

Technical Field

The application relates to the technical field of eye vision, in particular to a teenager out-of-focus lens and glasses.

Background

At present, in the conventional microlens array teenager defocusing lens, a defocusing area generally presents ring zone distribution or even regular polygon distribution. When wearing a common microlens array out-of-focus lens for near distance use, a juvenile wearer tends to habitually look through the lower half of the lens, at which time the line of sight falls within the out-of-focus zone of the lens.

According to medical investigation, the adolescent myopia population is more prone to accommodative lag, namely: the use of actual accommodative responses in the near field eye does not keep up with the degree of accommodative stimulation. We refer to the visual behavior of the object rays directed toward the center of the macula and clearly imaged as "fixation". When accommodative lag occurs, since the accommodative behavior is not kept up with the accommodative stimulus, it is possible to select a microlens region having an additive positive refractive power to form a near gaze in order to form a near gaze by the behavior of the clear vision region. In this case, the clear vision correction area of the parent lens constitutes a peripheral hyperopic defocus which is reversed for the wearer, and myopia progression is likely to be induced.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In the description of the present application, it is to be understood that the terms "first", "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

The applicant has found that, at present, the proportion of myopia in adolescents exceeds 80%, and that refractive errors in adolescents have already taken up a significant proportion. Researches show that people with hyperopia and defocus at the periphery of retina are easy to catch myopia or cause myopia to deepen quickly, and animal experiments and clinical experience of a cornea shaping mirror show that the myopia and defocus formed at the periphery of retina is helpful for delaying myopia and deepening. Therefore, the microarray out-of-focus lens is used as a lens capable of inhibiting the rapid rise of myopia and is rapidly applied. The micro-array out-of-focus lens mainly forms the out-of-focus myopia by attaching micro-lenses around the central clear vision area of the lens and enabling the peripheral image of the retina to fall in front of the retina. It should be noted that the central area of the defocusing mirror and the area outside the microlens structure still follow the principle of sharp correction. The functional principle of the glasses worn at the moment is as follows: the macula center receives optical signals falling on the retina through the clear vision zone, forming a so-called "fixation". And the peripheral area of the retina receives the optical signal falling in front of the retina, forming peripheral defocus. The lower half of the lens is often used habitually when the wearer looks down at close distances, a so-called "glimpsing" action. The center of the line of sight will then pass through the microlens area. Under normal accommodation, the center of the macula lutea of a human eye is still imaged by the clear vision area in the peripheral gap of the microlenses, while the periphery of the retina forms myopic defocus through the microlenses. However, in consideration of the large proportion of people with adjustment lag in myopic teenagers, the adjustment action of the part of people may not be followed up at the moment, so that the center of the macula lutea is clearly imaged through the micro-lens area, and the periphery of the retina forms hyperopic defocus through the clear vision area, thereby destroying the design principle of the lens periphery of myopic defocus. Therefore, it is desirable to design a new out-of-focus lens to solve the above technical problems.

Referring to fig. 1, there is provided an out-of-focus lens, comprising a mother mirror 100, a first array 200 and a second array 300; the mother mirror 100 includes an optical center 101, a first region 102 surrounding the optical center 101, and a second region 103 communicating with the first region 102; a first array 200 is arranged around the edge of the first region 102, the first array 200 comprising a plurality of groups of first microlenses 201 connected to each other; a second array 300 is arranged around the edge of the second region 103 away from the first region 102, the second array 300 comprising a plurality of groups of second microlenses 301 connected to each other; wherein, the refractive power of the second microlens 301 is larger than that of the first microlens 201.

By arranging the second area 103, which is equivalent to a clear vision correction area when teenagers read on the mother mirror 100, and arranging a row of second arrays 300 at the edge of the second area 103 far away from the first area 102, the second arrays 300 can adjust the action of next glance, and since the second microlenses 301 forming the second arrays 300 have larger refractive power, people can feel very uncomfortable when the sight line is positioned in the second arrays 300 after wearing the defocused lenses, and then the brain can direct the sight line of people to move and search for an area which is easier to image clearly, thereby further reducing the 'watching' possibility of teenagers. Through increasing a second area with first region intercommunication, clear vision correction area when having increased the back of wearing glasses and closely using the eye after the glasses, the second area 103 can effectively reduce teenagers because the eye "adjusts and delays" and "stares at the regional" reverse defocus that brings of microstructure, the near-sighted out of focus stimulus function in the off-focus area of assurance, the second area 103 has effectively increased the reliability that the near-sighted of delaying of out of focus lens deepens, can reduce the possibility that wears the back of glasses and form "stare" through the microlens region under the circumstances that does not increase first regional size, when guaranteeing out of focus stimulus effect, people's eye has reduced because of the regional reverse far-sighted out of focus risk that the action probably caused of staring at through the microlens, make this out of focus lens have higher myopia progression function that delays.
