Aspherical lenses that use retinal competition to control the growth rate of the eye axis

The present invention relates to an aspherical lens that utilizes retinal competition to control the growth rate of the eye axis, especially after the lens is worn on the eyeball, the optical zone of the lens is capable of producing retinal competition in the retina of the eyeball so as to control the growth of the eyeball. Speed, and then effectively delay the deepening of near and farsighted deviation, so as to achieve the effect of correcting and improving nearsightedness and farsightedness.

According to, myopia and hyperopia can seriously affect a person's ability to function without visual aids, and high myopia also increases the risk of developing eye diseases, such as: high myopia Risk of conditions such as glaucoma.

Therefore, in order to correct myopia or hyperopia, it is necessary to wear frame glasses or contact lenses to correct vision, so that the focus moves forward or backward to present a clearer image on the retina, which is then used to solve myopia or hyperopia. However, wearing frames Glasses or contact lenses can only resolve myopia or hyperopia when worn, and cannot slow the progression of myopia or hyperopia.

Therefore, how to solve the above-mentioned deficiencies and inconveniences is the direction of research and improvement that is urgently desired by the relevant practitioners in this industry.

Therefore, in view of the above-mentioned deficiencies, the inventor has collected relevant information through various After evaluation and consideration, and with years of experience accumulated in this industry, through continuous trials and revisions, the patentee who designs the aspheric lens that uses retinal competition to control the growth rate of the eye axis.

The main purpose of the present invention is that the inside of the lens includes an optical zone that causes the retina of the wearer's eyeball to produce the phenomenon of retinal competition. When the lens is worn on the eyeball, the retina of the eyeball will produce the phenomenon of retinal competition to transmit The phenomenon of retinal competition can control the growth rate of the eyeball, thereby effectively delaying the deepening of near-sighted and far-sighted deviations, so as to achieve the purpose of correcting and improving near-sightedness and farsightedness.

In order to achieve the above purpose and effect, the technical means and structure adopted by the present invention, the preferred embodiments of the present invention are hereby described in detail, and the features and functions are as follows, so as to be fully learn.

Please refer to Figures 1, 2, and 3, which are schematic plan views of the present invention, the optical path diagram of the lens that produces a blurred image around the center, and the optical path diagram of the lens that produces a clear image around the center. The lens 1 (such as the lens 1 of a contact lens or the lens 1 of a framed spectacles, etc.) includes an optical zone 11 inside the retina 21 of the wearer's eyeball 2 to generate retinal rivalry, and is located in the optical zone. 11. A central optical zone 111 is formed at the center for light to pass through to be imaged on the central imaging zone 211 (macular portion) of the wearer's retina 21, and the periphery of the central optical zone 111 is surrounded by a periphery imaged around the central imaging zone 211 The peripheral optical zone 112 on the image area 212 (the peripheral image area 212 is around the macula), and the outer side of the optical area 11 of the lens 1 is surrounded by the blind area 12 of the non-visual area, and the central image area 211 includes A central clear image area 2111 for focusing light to present a clear image and a central defocused image area 2112 outside the central clear image area 2111 to present an out-of-focus image, in addition, the peripheral image area 212 includes a peripheral area for focusing light to present a clear image Outside the clear image area 2121 and the surrounding clear image area 2121, a peripheral out-of-focus image area 2122 where an out-of-focus image is presented.

When the present invention is actually used, the lens 1 can be worn on the eyeball 2 of the wearer, so that the light can pass through the optical zone 11 of the lens 1 and be projected to the retina 21 behind the eyeball 2, which passes through the optical zone The light from the central optical zone 111 and the peripheral optical zone 112 of 11 will be imaged on the central image zone 211 and peripheral image zone 212 of the retina 21 respectively. At this time, the imaging area on the central image zone 211 of the retina 21 and the peripheral image zone The ratio of the imaged areas on 212 would be at a level that would allow retinal 21 to produce retinal competition. The retinal competition phenomenon can be generated in the retina 21 through the optical zone 11 of the lens 1, so that the retinal competition phenomenon can be used to control the growth rate of the eye axis, thereby effectively delaying or preventing the aberration of near and farsightedness from deepening. Achieve the effect of correcting nearsightedness and farsightedness.

And the above two kinds of lenses 1 can both make the retina 21 of the eyeball 2 produce the phenomenon of retinal competition. In the first case (as shown in FIG. 2 ), the light is focused on the retina 21 , so that the center of the central image area 211 is focused. The clear image area 2111 is located at the center of the retina 21, so that the peripheral out-of-focus image areas 2122 of the peripheral image area 212 are located around the central clear image area 2111, thereby generating a blurred image around the center clear image, and the second case ( As shown in FIG. 3), the light rays are focused around the retina 21, so that the central out-of-focus image area 2112 of the central image area 211 is located at the center of the retina 21, so that the peripheral clear image area 2121 of the peripheral image area 212 is located at the center of the retina 21. Around the central out-of-focus image area 2112 , a clear image around the central blur is generated. The above two situations can cause the retina 21 to produce a retinal competition phenomenon, which is used to correct nearsightedness and farsightedness.

The imaging area on the central image area 211 of the retina 21 is preferably smaller than the imaging area on the peripheral image area 212, but in practical applications, the imaging area on the central image area 211 of the retina 21 is the same as the image area on the peripheral image area 212. The predetermined range of the ratio of the imaging area can be between 10% and 40%, so that the retina 21 of the eyeball 2 can effectively generate the retinal competition phenomenon.
