Description

TECHNICAL FIELD The present invention relates to spectacles, spectacle lenses, and spectacle lens seals that can improve concentration when playing sports or studying, for example.

Conventionally, spectacles having pinholes (hereinafter referred to as "pinhole spectacles") have been proposed to prevent vision loss and restore vision. Pinhole glasses make use of the pinhole effect in which the depth of focus is deepened and the object can be seen clearly by narrowing the range where light (image) enters. The pinholes of the pinhole glasses are, for example, circular holes having a diameter of about 0.8 mm to 2 mm, and may be singular or plural.
For example, Patent Document 1 discloses pinhole glasses in which four pinholes are arranged in a cross shape.
Japanese Industrial Standards (JIS) stipulate that lenses with a luminous transmittance of 8% or less are not intended for driving or road use.

FIG. 11 is a plan view of a spectacle lens seal according to a third embodiment; FIG. 8 is a cross-sectional view taken along line AA of FIG. 7;

The spectacles of the present invention are, for example, spectacles that can improve concentration when playing sports or studying. A spectacle lens is composed of one field hole provided in the central part and an opaque non-central part (field hole peripheral part) surrounding the field hole. The spectacle lens of the embodiment can be produced by processing a normal spectacle lens. That is, the spectacle lens of the embodiment may be a glass lens or a plastic lens. Acrylic resins, polycarbonate resins, polyurethane resins, allyl diglycol carbonate (ADC), urethane-based resins, and the like are known as base materials for plastic lenses, and plastic lenses made of these base materials can be employed.

The opaque non-central portion is the area around the viewing aperture provided to allow the wearer to focus on the object viewed through the viewing aperture, to the extent that incident light from the non-central portion does not form an image on the wearer's retina. is the opacity of the . For the non-central portion, for example, it is disclosed that a commercially available transparent spectacle lens is subjected to a clouding process, or a process that reduces the luminous transmittance (visible light transmittance) to 8% or less. When working in a dark place, the luminous transmittance of the non-central part may be increased to increase the amount of light, but when working in a bright place, the luminous transmittance of the non-central part should be decreased. By doing so, the incidence of disturbance light may be reduced. In any event, incident light from opaque non-central portions does not form an image, allowing the wearer to focus on objects incident through the viewing aperture. The portion of the spectacle lens that is not cloudy is the viewing hole.

The viewing aperture consists of a circular hole with a diameter of 10-17 mm. Preferably, it consists of a circular hole with a diameter of 11-16 mm or 12-15 mm. The size of the visual field hole is set to this size because the size of the cornea is about 12 mm. This is because the Since the size of the visual field hole is approximately the same as the size of the cornea, the feeling that the field of view is blocked by a wall does not occur when wearing pinhole spectacles. Also, by setting the size of the visual field hole to a certain size or less, the viewpoint can be concentrated on one point. This is particularly significant when performing certain actions or playing sports (eg, putting in golf) where it is important to keep the viewpoint from moving.

As a general rule, the eyeglass lens is provided with a viewing hole at a position where the center of the eyeglass lens (optical center) coincides with the center of the viewing hole. At this time, it is preferable to measure the interpupillary distance of the wearer and match the center of the pupil with the center of the viewing hole.
Although the visual field hole can be formed by a through hole, it is preferable to provide a vision correcting function by using a lens. The viewing aperture can consist of either a transparent lens or colored so-called sunglasses. The spectacle lens forming the viewing aperture and the non-central portion can also be used for sunglasses with a gradation.
The spectacles of the present invention may be produced by attaching a spectacle lens seal having one viewing hole and an opaque non-central portion (peripheral portion of the viewing hole) to commercially available spectacles. Also, like so-called clip-on sunglasses, the spectacles of the present invention may be configured by attaching clip-on type lenses that are hooked to spectacle frames of commercially available spectacles with fasteners. Also, a pair of hinges for flipping up a pair of spectacle lenses may be provided to constitute flip-up spectacles.

In the eyeglasses of the present invention, the size of the visual field hole is equal to or slightly larger than the size of the cornea. It allows you to concentrate on your work. In addition, by concentrating the viewpoint on one point, it is possible to create a state in which the axis of the body does not move even when exercising. The work (use) targeted by the spectacles of the present invention includes, for example, reading, studying, and work using a personal computer, but is not limited thereto. The glasses of the present invention are also suitable for use in so-called closed-skill sports (e.g., golf, baseball pitcher, basketball free throw, soccer free kick and penalty kick, billiards, darts, bowling, e-sports) to increase concentration. is. Especially, it is suitable for realizing the action to keep the eyes on the target from the preparatory motion to the moment of the meeting when performing the exercise of meeting (hitting, kicking or throwing) a stationary object such as a ball. is. Furthermore, it is suitable for relieving symptoms of children with developmental disorders such as attention-deficit/hyperactivity disorder (ADHD) and learning disabilities (LD).

Although the details of the present invention will be described below with reference to embodiments, the technical idea of the present invention is not limited to the embodiments described below. Hereinafter, for convenience of explanation, the viewing direction of the spectacle wearer may be referred to as the front, and the direction opposite to the viewing direction may be referred to as the rear.

<First embodiment>
1 is a front view of the spectacles according to the first embodiment, FIG. 2 is a left side view of the spectacles according to the first embodiment, and FIG. 3 is a rear view of the spectacles according to the first embodiment. 4 is a photograph of the spectacles according to the first embodiment. The spectacles 1 of this embodiment comprise a spectacle frame 2 and a pair of spectacle lenses 3a and 3b.

The spectacle frame 2 is a known spectacle frame, and includes left and right rims 21a and 21b for fixing the spectacle lenses 3a and 3b; bridge 23 connecting the rims 21a and 21b of the body, nose pads 24a and 24b holding the nose from both sides to support spectacles, temples 25a and 25b provided with tip cells for hanging on the ears, and tips 22a and 22b. and hinges 26a, 26b for connecting the temples 25a, 25b.

The pair of spectacle lenses 3a, 3b includes field holes 31a, 31b provided in central portions and non-center portions 32a, 32b surrounding the field holes 31a, 31b. The spectacle lenses 3a, 3b are produced by subjecting a known spectacle lens to a clouding process to form non-central portions 32a, 32b. The clouding process is performed, for example, by performing a masking process on the portions to be the visual field holes 31a and 31b, followed by sandblasting (grinding) in which fine sand is blown, and then removing the masking. After sandblasting, the surface may be chemically treated with hydrofluoric acid to form a fine-textured milky-white lens, and then the masking may be removed. The lenses before processing used for producing the spectacle lenses 3a and 3b may be prescription lenses or non-prescription lenses. Further, it may be a transparent lens or a color lens. Further, known processing applied to spectacle lenses, such as blue light cut processing, scratch prevention processing, and prism correction processing, may be applied.

The visual field holes 31a and 31b are provided one each at the central portions of the left and right spectacle lenses 3a and 3b. Since the opening areas of the visual field holes 31a and 31b are not as small as those of pinhole spectacles, it is possible to secure a sufficient visual field for working or playing sports.
Table 1 shows the results of evaluation by a player when the eyeglasses 1 having the circular visual field holes 31a and 31b with different diameters were produced and golf putters were put. By wearing the spectacles 1 of the present embodiment, it is possible to realize a stroke motion in which the head remains while the line of sight is directed toward the ground when putting a golf ball. In other words, the head position, which is maintained perpendicular to the ground before the stroke, causes a blurring of the body axis as the line of sight follows the ball position during the stroke. It can be eliminated by providing it and narrowing the field of view. In addition, since the field of view is narrowed to a range of about 1 to 1.5 m in diameter centered on the golf ball, concentration is not hindered by visual information other than the golf hole.

[Table 1]

Table 2 shows the effect of wearing the spectacles 1 of the present embodiment.
[Table 2]

According to the spectacles of the first embodiment described above, the wearer's visual field is narrowed to the range of the visual field holes 31a and 31b, so that the wearer's concentration can be enhanced. Here, the field holes 31a and 31b can be not only lenses with prescription, but also can be subjected to known processing applied to eyeglass lenses such as blue light cut processing, scratch prevention processing, and prism correction processing.
In addition, since a certain amount of light is incident from the non-central portions 32a and 32b, the field of view can be narrowed without darkening the field of view unlike pinhole spectacles. It is possible to focus on the object visible through the holes 31a and 31b.
In addition, since the field holes 31a and 31b having wide opening areas are provided in the central portion of the lens, respectively, there is no problem that the periphery of the holes looks like a mesh when using pinhole spectacles.

<Second embodiment>

The spectacle lens 103 according to the second embodiment has a circular shape when viewed from above, and includes a transparent viewing hole 131 provided in the central portion and an opaque non-central portion 132 surrounding the viewing hole 131 . The spectacle lens 103 is produced by subjecting a known spectacle lens to a clouding process. Here, the spectacle lens to be clouded may be a colored lens, or may be a lens before being subjected to cutting and polishing processing for adding power. Arbitrary curved spherical and aspherical lenses can also be used. The method of clouding is the same as in the first embodiment. For example, after masking the portion to be the visual field hole 131, it is formed by sandblasting (grinding) in which fine sand is sprayed, and the masking is removed. It is formed.
The spectacle lens 103 according to the second embodiment is put into a known lens surface cutting device, and after being subjected to cutting and polishing processing to obtain a desired dioptric power, it is ground with a whetstone into a shape that fits in the frame of the spectacle frame. It is edged and used by attaching it to the spectacle frame.

A spectacle lens seal 201 according to the third embodiment includes a mount 202 , a pair of lens portions 203 a and 203 b , and a release sheet 204 . As shown in FIG. 8, the mount 202 has spherical convex portions 205a and 205b that contact the rear surfaces of the pair of lens portions 203a and 203b.
An adhesive layer (not shown) is formed on the rear surface of the integrally formed lens portions 203a and 203b and the release sheet 204, and is laminated on the second layer 202 via the adhesive layer. Since the outer edges of the lens portions 203a and 203b are separated by the half-cut lines 233a and 233b that do not reach the mount 202, the lens portions 203a and 203b can be separated from the mount 202 independently.

The lens portions 203a and 203b are circular in top view, and include transparent viewing holes 231a and 231b provided in the central portions and opaque non-central portions 232a and 232b surrounding the viewing holes 231a and 231b. The non-central portions 232a and 232b are subjected to opaque processing having translucency. Here, the viewing apertures 231a, 231b and the non-central portions 232a, 232b may be transparent or colored.
In the spectacle lens seal 201 according to the third embodiment, the shape of the outer edge of the pair of lens portions 203a and 203b is adjusted to match the spectacle lens by cutting the mount 202 together with scissors, and the pair of spectacle lens peeled off from the mount 202 is adjusted to fit the spectacle lens. The lens parts 203a and 203b are attached to the spectacle lens for use.

According to the spectacle lens seal of the third embodiment described above, spectacles having the same effects as those of the first embodiment can be realized by attaching the spectacle lens seal to arbitrary spectacles. .
