Description

Simulated eye lens re-examination device

The present invention relates to a lens re-inspection device for simulated eyes. In particular, it refers to the image parameters obtained after projecting light through two projectors and passing through (glasses) lenses as a basis for (glasses) lens modification. device.

The eyes are the windows to the human soul. Through the eyes, we can see the real situation outside. However, the eyes, like many human organs, may have abnormalities, whether due to congenital or acquired reasons, resulting in poor vision, such as out of focus ( Refractive errors such as nearsightedness or farsightedness) or dispersion (such as strabismus or astigmatism).

With the development of optical technology, the advent of (glasses) lenses will undoubtedly provide good assistance to people with eye abnormalities. Qualified optometrists have a sophisticated theoretical foundation and many years of practical experience, and can accurately measure whether the patient's eyes are refractive. etc. However, because there are still differences between the comprehensive optometre and trial-fitting frames used in the optometry environment and the glasses that are configured after the optometry procedure, many opticians often still feel uncomfortable when wearing the refracted (glasses) lenses. Visual discomfort occurs.

In practice, although (glasses) lenses are formulated based on the wearer's visual preferences and the optometrist's experience and judgment, due to irreversible economic considerations after grinding (glasses) lenses, even if the wearer feels discomfort after wearing them (glasses) lenses will be reluctantly used under the persuasion of the optometrist.

In view of this, the inventor relied on his accumulated experience and technology in manufacturing various optical eyewear products to conduct research and improvement on whether conventional (glasses) lenses actually meet the needs of wearers. After continuous research and experimental improvements, he finally developed this invention. Invented lens re-examination device that simulates eyes.

Therefore, the present invention aims to provide a lens re-inspection device that simulates eyes, which uses two projectors to re-inspect the polished (glasses) lenses, so that the polished (glasses) lenses can truly meet the needs of the wearer. .

According to the lens re-examination device of simulated eyes of the present invention, (glasses) lenses are respectively installed at the front ends of two projectors, and then the two projectors project light through the (glasses) lenses, and the image parameter values are obtained at the far end. , as the basis for whether the (glasses) lenses need to be modified again, is the second purpose of the present invention.

According to the lens re-examination device for simulating eyes of the present invention, the practical method is that the two projectors are installed on an adjustment support mechanism, and the projection angles can be adjusted up, down, left, and right, so as to project light from various angles. Confirming whether the focus, curvature, power, etc. of (eyeglasses) lenses are correct is a key aspect of the present invention. Another purpose.

According to the lens re-inspection device that simulates the eyes of the present invention, various image parameters can be obtained through the image obtained by the intersection position of the light projected by the two projectors after passing through the (glasses) lens, which can be used as a (glasses) lens modification tool. Basis is another object of the present invention.

In order to facilitate the review committee to have a further understanding of the purpose, shape, structural device characteristics and functions of the present invention, the structure of the present invention is described in detail below with examples and drawings:

Figure 1 is a schematic plan view of an embodiment of the lens re-examination device for simulating eyes according to the present invention.

Figure 2 is a schematic three-dimensional view of an embodiment of the lens re-examination device for simulating eyes according to the present invention.

Figure 3 is a schematic plan view of the lens re-examination device for simulating eyes according to the present invention.

Figure 4 is a schematic diagram of the far-end image when the lens re-examination device for simulating eyes of the present invention is implemented.

The lens re-examination device of the simulated eye of the present invention, as shown in Figure 1, is provided with an adjustment support mechanism 100. The adjustment support mechanism 100 is equipped with two projectors 210 and 220. The adjustment support mechanism 100 is provided with An adjusting mechanism 301, 302... is provided. The adjusting mechanism 301, 302... can be combined with a universal joint assembly, a guide groove 311, 312, etc. to control the two projectors 210, 220 to move up and down respectively. , left, right, and even the adjustment of the projection angle of the projected light. A (glasses) lens holder 410, 420 is respectively provided on both sides of the front end of the adjustment support mechanism 100. The (glasses) lens holder 410, 420 is located at the front end of the two projectors 210, 220, on which the (glasses) to be inspected can be placed. ) lenses 510, 520. Thereby, light is projected through the two projectors 210 and 220 to pass through the (glasses) lens, and the (glasses) lens is re-inspected.

When the projectors 210 and 220 project light (such as a straight beam), the image (e) obtained at the far end through the (eyeglasses) lens will not change when viewed by normal human eyes. However, if the projection light passes through the (glasses) lenses 510 and 520 and is re-projected, if other variant images are obtained, it means that the (glasses) lenses are abnormal and must be adjusted again to ensure that the projection light passes through the lenses. (glasses) lenses until normal images are obtained.

When the lens re-inspection device of the present invention is implemented, as shown in Figure 3, the two (glasses) lenses 510 and 520 are arranged at the front ends of the two projectors 210 and 220, and the two projectors 210 and 220 are used. There is an included angle (d) between the projected light rays, and then using the principle that the visual image is the fusion of the images obtained by the left and right eyes respectively, when the two projectors 210 and 220 respectively project light through the (glasses) lenses 510 and 520, Obtain an image at the far end point (e) of the distance a. If the image is the image (A) in Figure 4, it means normal. If the image obtained at endpoint (e) is the (B) image in Figure 4, it is a double cross, or the (C) image It is tilted, or the (D) and (E) images are disproportionately large or small, which means that the (glasses) lens is abnormal. At this time, the upper, lower, left, and right positions of the two projectors 210 and 220 are adjusted by the adjustment mechanism 300 until the image obtained is a normal image of the (A) image. The angle, position and other parameters of the adjustment process of the two projectors 210 and 220 can provide the basis for (glasses) lens grinding. Therefore, the optimal distance between the projectors 210 and 220 is the interpupillary distance (Pd). What is adjusted by the adjustment support mechanism 100 is to make the distance between the (glasses) lenses 510 and 520 equal to the interpupillary distance between the two eyes of the spectacle wearer. .

The lens re-inspection device for simulating eyes of the present invention, through the above-mentioned operations, can indeed provide re-inspection of (glasses) lenses. The parameters after re-inspection can be used as the basis for the glasses manufacturer to grind them, so that the wearer can obtain the results that are indeed consistent with the requirements. glasses for vision.

Based on the above, the lens re-inspection device for simulating eyes of the present invention does have an unprecedented innovative structure. It has not been seen in any publications, and there is no similar product on the market. Therefore, it has novel applications. No doubts. In addition, the unique features and functions of this creation are far beyond what is commonly used, so it is indeed more progressive than conventional use. It complies with the requirements for applying for a creation patent under my country's patent law, and a patent application is filed in accordance with the law.

It should be noted that the above are the preferred specific embodiments of the present invention. If changes are made according to the concept of the present invention, the functional effects thereof do not exceed the spirit covered by the description and drawings. in this hair Within the scope of Ming, I will give it to Ming.
