Description

Refractive error treatment glasses

Technical Field

The international classification number of the present invention is G02C 7/02. The invention relates to a pair of glasses, in particular to a pair of glasses capable of improving the vision of a patient with myopia and hyperopia.

Background Art

Refractive does not mean that parallel rays 5 meters away are refracted by the refractive system of the human eye and cannot be clearly imaged on the retina, including myopia, hyperopia and astigmatism. Among them, myopia patients account for the vast majority. At present, medical treatment for refractive error is divided into two methods: (1) contact treatment. This method includes laser surgery to cut the cornea, Orthokeratology, and the like. (2) Non-contact treatment. This method includes various myopia treatment instruments, myopia treatment glasses, and the like.

Both of these methods have a large number of patents worldwide, but they all have their limitations. The advantage of contact treatment is that it has a quick effect. The disadvantage is that it requires a foreign body to directly contact the eyeball, so the risk is high and it is not suitable for everyone. Non-contact treatments use a lot of methods, but the effect is not significant, because the myopia treatment device must use special time for treatment, so most people can not adhere. Myopia treatment glasses such as bifocal glasses and progressive multifocal glasses have problems of wearing discomfort.

Bifocal glasses are designed for the elderly who have both myopia and presbyopia symptoms. These elderly people need to wear myopia glasses when they are far away and wear reading glasses when they are close. The lens of the bifocal glasses is designed such that the upper half of the lens (referred to as the far vision area) is a myopic mirror, and the lower half (referred to as the near vision area) is a reading glasses. However, due to the different degrees of different regions on the same lens, wearing bifocal glasses can lead to adaptive problems such as dizziness and headache. In order to improve the adaptability of the human eye, progressive multifocal glasses have appeared. Such glasses add a transitional zone of varying degrees between the far-field and the near-field. The distance zones of some bifocal glasses and progressive multifocal glasses are designed as high-degree myopia mirrors, and the near-field is designed as a low-degree myopia mirror. Some medical research abroad shows that wearing such glasses in adolescent myopia patients can delay the development of myopia.

Compared with the dual-light myopia, progressive multifocal myopia has reduced the adaptability of the human eye due to the increase of the transition zone, but it has not solved the problem fundamentally. For young myopia patients, the adaptability is more influential. . In addition, these glasses can only delay the development of myopia, and can not really improve vision. But we can conclude a method of myopia treatment, which requires different degrees of lens for different distances of vision.

In 2008, American David De Angelis published The Secret of Perfect Vision (The Secret Of Perfect Vision). The book describes his own invention of myopia treatment, which is characterized by the use of the human eye's self-adapting biofeedback capabilities, constantly wearing lower degrees of glasses to treat myopia and hyperopia. David de Angelis pointed out in the book that when the eyeball adapts to the regular change of the glasses, it will trigger the automatic adaptation process of the human eye, such as a person with a degree of myopia of 300 degrees, long-term wear 200 In glasses, the actual myopia of the eyeball will decrease to 200 degrees. Therefore, the long-term use of his method, the degree of myopia will gradually decrease. This method can also be used to treat hyperopia. However, this method has two problems: (1) this method requires wearing a variety of different degrees of glasses, which is very inconvenient. (2) This method requires the human eye to have a strong self-adaptive ability, for most people. The efficiency of treatment is too low. There are also some patented technologies for treating myopia based on the principle of biofeedback, such as US7997725 Patent, but all are more complicated.

February 21, 1967, American physicist Luis Walter Alvarez's invented US Patent No. 3,305,294 is licensed. This patent describes an axial diopter change when two specially constructed lenses are moved in parallel in a vertical axis. We know that the traditional glasses are usually designed to be an integral multiple of 25 degrees due to the manufacturing cost, and the patent can be used to manufacture glasses with dynamic changes of any degree. U.S. Patent No. 7,980,690 describes a lens that can be used to dynamically adjust the degree of spectacles using the patented technology of 3,325,294. The inventor of the 7980690 patent, the Dutch Focus Vision Foundation (Stichting Focus on Vision Foundation) has produced products based on this patent. According to the website of the Dutch Focus Vision Foundation (http://www.focus-on-vision.org/), the purpose of the 7980690 patent is to provide a need for optometry for the poor in remote areas of developing countries with conditions behind. Cheap glasses that can adjust the degree by themselves.

It is not only a zoom lens technology of the patent No. 3305294. The US Patent No. 4190330, which was authorized on February 26, 1980, is also a technology that can change the focal length of a lens. This technique describes a lens that uses liquid crystal as a filling material, and its focal length can be changed by applying a change in voltage. U.S. Patent No. 7,475,985, owned by Pixel Optics, describes a lens that is based on the 4,190,330 patent. The purpose of this glasses is to change the degree of the lens by the change of voltage, thus achieving the function similar to the bifocal glasses. Pixel Optics has produced one of these glasses, targeting customers who have both myopia and presbyopia.

Other zoom lens technologies are also U.S. Patent No. 3,617,718, issued on Dec. 15, 1964, and assigned to U.S. Patent No. 3,598,479, issued on Aug. 10, 1971.

However, the derivatives of these zoom lens technologies are designed and promoted as a variable degree of corrected vision glasses. Corrective vision Vision) just by wearing glasses to make the vision normal, no one has improved the vision based on these zoom glasses technology (improving Vision) glasses. Improving eyesight means that you only need to wear glasses that are lower than the previous level to achieve the previous level of vision. The process of treating myopia and hyperopia is also the process of improving vision.

Technical Problem

The technical problem to be solved by the present invention is to solve the problem that the current myopia treatment apparatus and the myopia treatment glasses have low practicality and low efficiency, and provide a glasses which can improve the vision of myopia and hyperopia patients, and an operation method of the treatment process.

Technical Solution

The principle of the invention is to use the self-adjusting function of the human eye to provide a glasses that can change the myopia or the degree of farsightedness with time. The wearer can use it as normal glasses, and gradually adapt to lower-level glasses during normal use. Achieve the therapeutic effect of improving vision.

In order to solve the technical problem, the technical solution provided by the present invention is that the glasses are composed of six main parts: (1) central processing unit (CPU) (2) electronic clock (3) array data loss of lens degree (4) smart phone Commonly used gravity sensors (5) electronic clock start and stop buttons, gravity sensing start and stop buttons, distance mode manual selection button (6) glasses with precise degrees of change (ie zoom glasses).

The distance mode is divided into two types: the far view mode and the near mode. Looking far mode means that the wearer needs to look at distant objects. At this time, whether it is myopia or hyperopia, the required degree will be higher. Looking at the near mode means that the wearer needs to look at the near object. At this time, whether it is a nearsightedness or a farsighted patient, the required degree will be relatively low.

The manual selection of the distance mode means that when the gravity sensor is not working, the wearer specifies whether it is currently looking far or near, which is mainly suitable for daily work and life with small distance changes.

The gravity sensor is suitable for young myopia patients to use when the distance changes frequently. For example, when class is in the classroom, sometimes it is necessary to look at the distance blackboard, and sometimes it is necessary to look at the textbook or writing near. Under normal circumstances, the head is to look at the distance, the head is to look close, once the gravity sensor starts working, it can automatically detect the wearer's head and head movements, to determine whether the wearer is currently looking at the distance or watching Near.

The array data format of the lens power change is: (a, b, c, d, e). a represents the left eye or the right eye, b represents time, in seconds, c represents the lens power, d represents the myopia lens or the far vision lens, and e represents whether to look at the far mode or the near mode.

For example, (1, 1, 300, 1, 1) means that the left lens becomes a 300 degree myopia in the first second when looking far. (1 , 60, 290, 1, 1) means that when looking far, the left lens becomes a 290 degree myopia in the 60th second. (2,1,100,1,2) means that the right-eye lens becomes a 100-degree myopia in the first second when the near-eye lens is viewed. (2, 60, 90, 1, 2) means that the right-eye lens becomes 90-degree myopia at 60 seconds. The following is a table description.

左眼（1）右眼（2）Left eye (1) right eye (2)	时间（秒）Time (seconds)	镜片度数Lens degree	近视（1）远视（2）Myopia (1) hyperopia (2)	看远（1）看近（2）Look far (1) look close (2)	解释Explanation
11	11	300300	11	11	看远时左眼镜片在第1秒钟变为300度近视镜Looking far away, the left lens becomes a 300 degree myopia in the first second.
11	6060	290290	11	11	看远时左眼镜片在第60秒钟变为290度近视镜Looking at the distance, the left lens becomes a 290 degree myopia in the 60th second.
22	11	100100	22	22	看近时右眼镜片在第1秒钟变为100度远视镜When you see near right, the right eyeglasses become 100 degrees far vision mirror in the first second.
22	11	9090	22	22	看近时右眼镜片在第60秒钟变为90度远视镜When you are close, the right eyeglasses become a 90 degree far vision mirror in the 60th second.

The technical solution has three modes of operation: (1) the electronic clock is not activated (2) the electronic clock is activated but the gravity sensor is not activated (3) both the electronic clock and the gravity sensor are activated.

When the electronic clock is not activated, the gravity sensing button and the distance mode manual selection button are invalid, which is an ordinary glasses.

When the electronic clock is started but gravity sensing is not activated, the operation method is: (1) input the array data of the lens power change into the data memory (2) the CPU reads the data in the data memory once per second, and selects the button according to the distance mode manual selection button. , matching array data. If the current mode is the first second, the distance mode manual selection button is in the far view mode, and the distance mode degree of the first second of the change time is matched, and the degree change request is sent to the zoom glasses (3) the zoom glasses are changed to the settings in the array data. Degree.

When both the electronic clock and the gravity sensor are activated, the distance mode manual selection button is invalid, and the gravity sensor will automatically detect the wearer's head and bow movements, and automatically determine whether it is looking far or near. Other operations are the same as when gravity sensing is not activated.

After a set of degrees of change data has been used for a period of time, new array data needs to be used based on the wearer's vision. When the maximum degree in the array data is getting smaller and smaller, it means that the treatment has an effect and the wearer's vision is improved.

Advantageous Effects

Compared with the conventional myopia treatment device, the technical solution can enable the wearer to treat at any time in daily life, and the treatment efficiency is greatly improved.

Compared with conventional myopia treatment glasses such as dual-light and progressive multifocal glasses, the overall lens power in the present technical solution, although changing with time, is the same degree at the same time, and can solve the adaptation problem of the human eye. It can improve the vision of patients with myopia and hyperopia, rather than just slowing down the development of myopia.

Compared with the treatment method of David de Angelis, the technical solution can precisely adjust the change of the lens degree according to the human eye adaptability of different people. People with strong eyesight adaptability can speed up the change of lens power in time. People with weak eyesight adaptability can slow down the speed of lens changes in time, thus greatly improving the treatment efficiency of refractive error. Moreover, due to the use of the gravity sensor, the burden on the eye when looking at the vicinity can be reduced, and the treatment efficiency can be further improved.

Best Mode

The functions of modules (1), (2), (3), (4), (5) can be implemented using an integrated circuit composed of a programmable storable microcontroller and a gravity sensing chip. The implementation of module (6) is related to the specific zoom glasses technology. An embodiment based on the U.S. Patent No. 7,980,690 is given here. This patent describes a zoom lens based on the patent No. 3,305,294, and FIG. 2 is a part of the structural schematic of the patent, which describes the rotation of the knob by mechanically rotating the knob 23R through a mechanical transmission structure. It is the axial translation of the lens to achieve a change in the power of the lens. The partial structure of the 7980690 patent can be modified to become the module (6) of the present invention.

In order to allow the module (6) to automatically and precisely adjust the degree of the lens, the micro stepper motor of Figure 2 can be used. Motor) instead of the knob 23R. The stepping motor can convert the electric pulse signal into precise angular displacement. Each electric pulse signal can rotate the rotating shaft of the motor at a fixed angle, so that the electric motor can be used to control the stepping motor to rotate at a specific angle. . After mechanical transmission, the angular rotation of the stepper motor can be translated into a precise translation of the lens. According to the description of the patent No. 3,305,294, the axial translation of the lens has a linear relationship with the change in the degree. We can calculate the degree of change of 1 unit, how long the corresponding lens needs to be axially translated, and then convert it to the angle that the stepper motor needs to rotate, and finally calculate how many electric pulses need to be driven to change the degree of one unit. Stepper motor. Then you can add the corresponding operation control code in the program of the microcontroller to realize the function of the module (6).

Mode for Invention

The invention can also be implemented using any other patented zoom lens technology, such as the US Pat. No. 7,475,985 patented by Pixel Optics, Inc., which describes a zoom lens in which the lens is filled with a liquid crystal material and the voltage can be varied. The arrangement of the liquid crystal material is controlled to achieve a change in the degree of the lens. Since the change in voltage has a linear relationship with the change in the degree of the lens, the degree of change can be precisely controlled by the electrical signal. Other patented zoom glasses are not exemplified.

Industrial Applicability

The functions of modules (1), (2), (3), (4), (5) can be implemented by an integrated circuit composed of a single chip microcomputer and a gravity sensing chip. With the development of the specific products of the Dutch Focus Vision Foundation and the American Pixel Optics Company, the zoom lens function of the module (6) is also fully industrially practical. At present, the world's smallest micro stepping motor, which is only 2 cm in diameter, can be used on glasses. In summary, the present invention has industrial applicability.
