Abstract

PROBLEM TO BE SOLVED: To provide a convenient and compact health tool for eyes without any heating factor and necessity of complicated machinery by forming a head fitting matter so that a pad containing a minus ion radiative material to abut on a position between an eye and an ear on fitting. SOLUTION: A mixture of equal quantities of β-ray radiative rare earth ore ceramic powder and amphibole powder is applied on a coarse nonwoven fabric via a vinyl acetate based adhesive, it is integrally overlapped on an elastic core material 4 preliminarily bent into a curvature larger than that of a face, and the whole part is formed together with surface cloth 5 into an eye mask by boring a hole 2 on a position corresponding to an eye. The elastic core material 4 which is a pad containing a minus ion radiative material is made so as to abut on a position between an eye and an ear. Thus, an easily fitting health tool for eyes, which is useful for preventing troubles of eye fatigue and low vision without disturbing working, is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an eye fatigue preventing device used for preventing disorders such as eyestrain and reduced visual acuity, or for maintaining eye health.

[0002]

2. Description of the Related Art Recently, many people suffer from eye troubles such as eyestrain and reduced vision due to long hours of contact with electronic devices such as personal computers and word processors and driving cars. For example, an eye patch that emits far-infrared rays toward the eyeball, or a device that causes the brain and nervous system to relax by blinking light from a closed eye at a specific cycle and so on.

[0003]

However, recently, excessive irradiation of the eyeball with an electromagnetic wave such as infrared rays, which is a heating factor, may cause deterioration of the crystalline lens and vitreous body and promote peroxidation. Since it has been pointed out that this may be a cause, there is a demand for a simple eye health tool that does not have such a heating factor and does not require complicated accompanying equipment. An object of the present invention is to provide a compact product that can meet such demands.

[0004]

In view of the above, the present inventor has made many trials and trials of eye-gap-shaped ones using various materials, and surprisingly, the following were found to be extremely remarkable. It was found to improve fatigue and disability.

[0005] That is, a head-mounted article formed so that a pad-like object (1) containing a negative ion releasing material hits at least the position (a) between the eye and the ear when worn, and a device for preventing eye fatigue. Is what you do.

The preferred form of the head-mounted object is an eye mask, and a portion corresponding to the eye when the head is worn is provided with a large hollowed hole (2) for ensuring a sufficient visual field. It is assumed that

In particular, when the entire eye mask is formed of a composite of a material (3) containing a negative ion releasing material and an elastic core material (4) which is excessively bent as shown in FIG. Thus, it can be naturally attached to the head only by elasticity, and the position from the eyes to the ears is naturally covered with such a pad-like material (1).

[0008] As a negative ion releasing material, for example, natural ore or its ceramics emit β-rays and those having pyroelectricity. Such as those applied to and supported on a sheet-like sheet are applicable.

[0009]

When the device of the present invention is worn on the head, since the negative ion releasing material is close to the face from the eyes to the ears, the oxidation-reduction potential in the vicinity is naturally lowered, and a peroxidation phenomenon harmful to the human body. Is thought to be suppressed, but it is unclear at this time how this directly relates to the prevention or recovery of eye fatigue and disability.

However, from the experience, it has been evident that wearing the device significantly reduces eye fatigue when operating a personal computer or driving a car for a long period of time, and the progress after the fact is very good.

The material should be applied to the part between the eye and the ear for some reason, and it is better to remove the eyeball part and leave it as an open space.

Although the solid theoretical elucidation is not the role of the present application, the porosity of the eyeball portion is relatively high and the heat release therefrom is relatively high. Therefore, the temperature is kept low despite good blood circulation. It is presumed that it has helped to reduce the alteration factors of ocular proteins such as oxidation and Maillard reaction.

The position from the eye to the ear is probably an important point such as the ocular muscle and its blood vessels and nervous system.
It may be related to meridians and acupuncture points in Oriental medicine.

EXAMPLE An equal mixture of β-ray emitting rare earth ore ceramic powder and hornblende powder was applied to a coarse nonwoven fabric via a vinyl acetate adhesive, and this was previously bent to a curvature greater than the curvature of the face. The elastic core material (4) thus formed is overlapped and integrated, and a hollow hole (2) is provided in the eye together with the surface cloth (5) to form an entire eye mask. When this was worn and the car was driven for a long distance (8 hours), there was no outflow of tears as usual, and eye fatigue and disability were significantly reduced. In addition, when asked for impressions of 10 personal computers and word processor user monitors, up to 9 persons recognized a clear difference, and were replied that they would greatly help reduce eye strain and vision loss.

[0015]

As described above, according to the present invention, there is an effect that it can be worn very easily and can prevent obstacles such as eye fatigue and reduced visual acuity without hindering work or the like.
