Description

Visual image enhancement method and special sight line diaphragm filter

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

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.

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

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.

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.

The technical solution of the present invention is as follows:

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.

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

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.

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.

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.

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.

Advantages of the invention -

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.

2. The visual image enhancement method and the visual line diaphragm filter of the present invention do not require eye muscle tension regulation and do not cause fatigue. The invention is particularly suitable for reading, or computer operation, or for leisure sightseeing, and is applicable to both normal eyes and abnormal eyes.

3. The visual image enhancement method and the visual line diaphragm filter of the present invention are highly versatile. An appliance that can be used by anyone and can be used as a public device. Users do not need optometry. DRAWINGS

Figure 2-3 Schematic diagram (including line of sight diaphragm filter). detailed description

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

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.

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).

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.
