Description

一种视觉图象增强法及专用视线光阑过滤器 技术领域  Visual image enhancement method and special sight line diaphragm filter
本发明涉及视觉图象增强及视线光阑过滤技术,属于人类工程学领域,具体地说 是一种视觉图象增强法及专用视线光阑过滤器。 技术背景  The present invention relates to visual image enhancement and line-of-sight filtering techniques, and belongs to the field of ergonomics, and more particularly to a visual image enhancement method and a dedicated line-of-sight diaphragm filter. technical background
自 1100年阿拉伯人发明透镜 900多年来(光学,人民教育出版社 1978年版, 148 页), 人们一直采用各类透镜增强眼睛的视觉效果。周知,近视眼的水晶体聚焦过度, 造成视觉图象模糊。 须佩戴适当的凹透镜, 用以预先发散视线光束。 远视眼的水晶 体聚焦不足,造成视觉图象模糊。须佩戴适当的凸透镜,用以预先汇聚视线光束。 对 于散光眼, 特别是不规则散光眼, 尚无法配制合适的透镜。  Since the Arabs invented lenses in 1100 for more than 900 years (Optics, People's Education Press, 1978, 148 pages), people have been using a variety of lenses to enhance the visual effects of the eye. It is known that the crystals of myopia are over-focused, causing blurred visual images. A suitable concave lens must be worn to pre-diverge the line of sight beam. The crystal of the farsighted eye is not focused enough to cause a blurred visual image. Appropriate convex lenses must be worn to pre-converge the line of sight. For astigmatic eyes, especially irregular astigmatism, it is not possible to formulate a suitable lens.
采用透镜改善视觉效果的缺点是: 每个透镜的参数是固定的, 不能随机应变。长 时间佩戴会使眼睛劳损, 视力进一步变差, 不断加大透镜曲率, 以至视力每况愈下。 发明内容  The disadvantage of using a lens to improve the visual effect is that the parameters of each lens are fixed and cannot be randomly strained. Wearing for a long time will strain the eyes, further deteriorate the vision, and constantly increase the curvature of the lens, so that the vision is getting worse. Summary of the invention
针对现有技术中透镜的缺点,本发明的目的在于提出一种视觉图象增强法及专用 视线光阑 ^滤器, 它不使用透镜, 作为现代眼镜技术的伴侣和补充, 有效地增强视觉 效果。  In view of the shortcomings of prior art lenses, it is an object of the present invention to provide a visual image enhancement method and a dedicated line-of-sight filter that does not use a lens and is a companion and complement to modern eyewear technology, effectively enhancing visual effects.
瞳孔是眼睛的光阑, 本发明再给眼睛佩戴一个视线光阑, 取代瞳孔的地位, 成为 眼睛光学系统的有效光阑 (孔径光阑), 通过这光阑的过滤, 在非正常眼视网膜上便 只留下了清晰图象, 达到增强视觉图象的目的。  The pupil is the pupil of the eye. The present invention then wears a line of sight to the eye, replacing the position of the pupil, and becomes an effective pupil of the optical system of the eye (aperture stop), through the filtering of the pupil, on the retina of the abnormal eye. Only a clear image is left, for the purpose of enhancing the visual image.
本发明的技术方案如下: ·  The technical solution of the present invention is as follows:
视觉图象增强法:给眼睛佩戴在两个视线光阑片材上设置视线光阑通光孔的视 线光阑过滤器,利用视线光阑过滤器除掉投入眼球而远离光轴的光线,保留靠近光轴 的光线, 排除球差干扰, 达到增强视觉图象的目的; 视线光阑过滤器的佩戴方法, 与 传统眼镜的佩戴方法相同。  Visual image enhancement method: a line-of-sight diaphragm filter that is provided with a line-of-sight aperture through a pair of line-of-sight aperture sheets, and uses a line-of-sight diaphragm filter to remove light that is directed away from the optical axis and retained. The light close to the optical axis eliminates spherical aberration and achieves the purpose of enhancing the visual image. The method of wearing the sight diaphragm filter is the same as that of the conventional glasses.
所述视觉图象增强法的专用视线光阑过滤器:为在两个视线光阑片材上设置视线 光阑通光孔结构, 通光孔直径可为 0.5-2毫米; 所述视线光阑通光孔可为规则的行列 点阵结构, 相邻视线光阑通光孔的中心距可为 3~5毫米;  The special line-of-sight diaphragm filter of the visual image enhancement method is configured to provide a line-of-sight aperture aperture structure on two line-of-sight aperture sheets, and the aperture aperture may be 0.5-2 mm; the line of sight aperture The light passing hole may be a regular row and column lattice structure, and the center distance of the adjacent sight line diaphragm light passing hole may be 3 to 5 mm;
1  1
确 认 本 所述视线光阑片材耳釆用不透明的片材;两个视线光阑片与眼镜框架之间的联接 采用可调结构, 使得两个视线光阑片在框架上的位置可上下、 左右、 前后进行调节, 可调幅度可为 5-10毫米, 以便适应不同人的眼睚和瞳距。 Confirmation The line of sight of the sight glass sheet is made of opaque sheet; the connection between the two line of sight diaphragms and the frame of the glasses adopts an adjustable structure, so that the positions of the two line of sights on the frame can be up and down, left and right, Adjusted before and after, the adjustable range can be 5-10 mm, in order to adapt to different people's eyelids and interpupillary distance.
本发明基于这样一种原理:在非正常眼视网膜上的模糊图象,不是一个纯粹的模 糊图象。 在模糊图象中还叠加着一个清晰图象。 当远离眼球光轴的光线不能聚焦在 视网膜上而产生模糊图象的时候,靠近眼球光轴的光线仍能聚焦在视网膜上而产生清 晰图象。就是说, 在非正常眼水晶体周边和水晶体中央两者之间, 存在着光学的非一 致性,相当于透镜的球差。这非一致性便是视觉图象模糊的根源。设法除掉远轴光线, 避开水晶体周边,在非正常眼视网膜上便只留下了清晰图象,达到增强视觉图象的目 的。 这便是本发明视觉图象增强法。  The invention is based on the principle that a blurred image on the retina of an abnormal eye is not a purely fuzzy image. A clear image is also superimposed on the blurred image. When light rays away from the optical axis of the eye cannot be focused on the retina to produce a blurred image, light near the optical axis of the eye can still focus on the retina to produce a clear image. That is to say, there is optical inconsistency between the periphery of the abnormal eye crystal and the center of the crystal, which is equivalent to the spherical aberration of the lens. This inconsistency is the source of visual image blur. Try to get rid of the far-axis light and avoid the periphery of the crystal. Only the clear image is left on the abnormal retina to achieve the purpose of enhancing the visual image. This is the visual image enhancement method of the present invention.
根据这一方法,本发明设计出一种视线光阑过滤器。在不透明的片材上设置小孔 光阑, 戴在眼前。 小孔光阑取代了瞳孔的地位, 成为眼睛光学系统的有效光阑。  According to this method, the present invention contemplates a line of sight diaphragm filter. Place a small aperture on the opaque sheet and wear it in front of your eyes. The small aperture diaphragm replaces the position of the pupil and becomes an effective pupil of the optical system of the eye.
该小孔光阑只准许投向眼睛的近轴光线通过,而阻断远轴光线, 因而也就避开了 水晶体周边,避开了它的不恰当的折射。这时候, 非正常眼视网膜上的图象应该是清 晰的。 原来的构想得到了实现。  The aperture stop only allows the paraxial rays that are directed toward the eye to pass, blocking the far-axis light, thus avoiding the periphery of the crystal and avoiding its improper refraction. At this time, the image on the retina of the abnormal eye should be clear. The original idea was realized.
本发明优点- Advantages of the invention -
1. 本发明视觉图象增强法及视线光阑过滤器有效地增强视觉效果。 能使人在佩 戴本过滤器时重现最好视力,使眼睛清晰可视区间扩大为 0到无限远。这是任何单个 透镜绝对办不到的。 通常眼睛看无限远处 (20米以外) 的景物是清晰的。 但是, 看 几厘米以内的东西反倒不清楚了 (儿童的近点为 7-8厘米)。 佩戴本视线光阑过滤器 使近点接近 0厘米。 于是, 把书贴近眼睛, 仍可阅读, 显现出人类视力的潜能。 1. The visual image enhancement method and the visual line diaphragm filter of the present invention effectively enhance the visual effect. It enables people to reproduce the best vision when wearing this filter, so that the clear visual range of the eye is expanded to 0 to infinity. This is absolutely impossible with any single lens. Usually the eyes are infinitely far away (20 meters away) and the scenery is clear. However, it is unclear to see something within a few centimeters (the child's near point is 7-8 cm). Wear this line of sight filter to bring the near point closer to 0 cm. Therefore, the book is close to the eyes, still readable, showing the potential of human vision.

本发明视觉图象增强法:给眼睛佩戴视线光阑过滤器,利用视线光阑过滤器除掉 投入眼球而远离光轴的光线, 保留靠近光轴的光线, 排除球差干扰, 达到增强视觉 图象的目的。  The visual image enhancement method of the invention adopts a sight-light diaphragm filter for the eyes, and removes the light which is input from the eyeball away from the optical axis by the sight-line diaphragm filter, retains the light close to the optical axis, eliminates the spherical aberration interference, and achieves the enhanced visual map. The purpose of the elephant.
图 2-1中 0是眼睛光轴上一物点, 0'是物点 0在眼球视网膜上的象点。 对于正 常眼, 物点 0发出的多条光线 OA, OB, OC, OD ......经水晶体 Cr折射后都汇集在 象点 0'。 一物点 0对应一象点 o'。 因而, 图象是清晰的。 ' 对于非正常眼, 靠近光轴 00'的近轴光线 OA, OB...能汇集于象点 0'。 而远离 光轴 00'的远轴光线 OC, OD...经水晶体 Cr周边的折射后不能如图中虚线所示像正 常眼那样汇集在象点 0,, 而是提前汇集 (近视 '), 或迟后汇集 (远视)。 在视网膜上 产生模糊的图象(图 2-2)。  In Figure 2-1, 0 is an object point on the optical axis of the eye, and 0' is the image point of the object point 0 on the retina of the eye. For the normal eye, the multiple rays OA, OB, OC, OD ... emitted by the object point 0 are collected at the pixel 0' after being refracted by the crystal Cr. An object point 0 corresponds to a pixel o'. Thus, the image is clear. For non-normal eyes, the paraxial rays OA, OB... near the optical axis 00' can be collected at the image point 0'. The far-axis rays OC, OD... far from the optical axis 00' cannot be collected in the image point 0 as shown by the dotted line in the figure as indicated by the dotted line in the figure, but are collected in advance (myopia'). Or later collection (farsightedness). A blurred image is produced on the retina (Figure 2-2).
图 2-3中 MN是一不透明片材的断面, 断面 MN靠近眼球而垂直于光轴 00'。 AB表示视线光阑片材上的一个视线光阑通光孔的直径。 光轴 00'穿过视线光阑通光 孔的中心。 视线光阑通光孔 AB只能让 A0B立体角以内的近轴光线通过, 经水晶体 Cr折射后都汇集在象点 0,。视线光阑通光孔 AB不准许 A0B立体角以外的远轴光线 OC, 0D...通过。 因此, 采用视线光阑通光孔, 排除了远轴光线, 对于非正常眼, 物 点 0在视网膜上的象点 0'也会是清晰的。  In Figure 2-3, MN is a section of an opaque sheet, and the section MN is close to the eyeball and perpendicular to the optical axis 00'. AB represents the diameter of a line of sight aperture on the line of sight diaphragm. The optical axis 00' passes through the center of the line of sight aperture. The line of sight aperture through hole AB can only pass the paraxial light within the solid angle of A0B, and is condensed by the crystal Cr to be collected at the image point 0. The line of sight aperture through hole AB does not permit the far axis rays other than the A0B solid angle OC, 0D... pass. Therefore, the use of the gaze aperture through the aperture eliminates the far-axis light. For an abnormal eye, the object point 0 on the retina is also clear.
