Abstract

PURPOSE:To provide a soft lens which can be sucked to goggles or sunglasses without degrees to change these goggles or glasses to the glasses with certain degrees, and further to protect eyes or lenses without changing degrees by forming the soft lens from such a material that can be easily deformed. CONSTITUTION:A plate material 2 with parallel surfaces and no degree consisting of a transparent material which hardly deforms such as glass or hard plastics is combined with a soft lens 1 having concave surfaces consisting of a soft synthetic resin material. The soft lens 1 is pressed from the lens side and deformed to adhere to the plate. Thus, a flat-concave lens is obtd. As an example of using this soft lens, the soft lens 1 having concave surfaces and comprising soft synthetic resin is adhered and fixed to protective glass of underwater glasses or inside of ski goggles so that a shortsighted person can wear these underwater glasses or goggles without wearing usual glasses and can observe the outside.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lens made of a deformable soft material.

[0002]

2. Description of the Related Art Conventional glasses use lenses made of transparent glass or hard plastic material.

[0003]

For example, when using underwater glasses, it is extremely inconvenient for a person with myopia to wear the glasses for myopia and then use the underwater glasses.

The same thing occurs in the case of ski goggles, which is not preferable.

The same applies to the case of using colored glasses or polarized glasses used in various works such as welding work.
In other words, this kind of glasses is inconvenient because it is necessary to wear ordinary glasses for myopia as well as colored glasses and polarized glasses because of the lack of power.

[0006]

The soft lens of the present invention comprises:
It is made of a deformable soft transparent resin material, and one surface thereof is a flat surface or a concave surface. A lens made of such a soft resin material, for example, one surface of which has a concave surface, is arranged by arranging the concave surface toward the flat surface or the concave surface side of a plate of glass or a hard synthetic resin material and pressing from the opposite side. It is used by giving a function of one eyeglass lens together with the plate-like body by adsorbing it.

When the shape of the soft lens of the present invention is flat on both sides, the soft lens is arranged on the concave side of a plate made of glass or a hard resin material such as another lens having another concave surface. It is pressed to be adsorbed to the plate-shaped body and combined with the plate-shaped body to form an eyeglass lens.

Further, by using a soft lens composed of two or more surfaces having different curvatures, a multifocal lens or a plurality of magnifying lenses having different magnifications can be integrated.

By adsorbing a soft lens having a smaller diameter to the spectacle lens by the same method, a multifocal lens having a degree of the spectacle lens itself and a degree of the lens including the spectacle lens and the soft lens is obtained. You can also do it.

EXAMPLES Next, examples of the present invention will be described.

FIG. 1 is a view showing a first embodiment of the present invention, in which 1 is a soft lens of the present invention, and 2 is a parallel lens made of a transparent material such as glass or hard plastic which hardly deforms. A flat plate-shaped body, the soft lens of this embodiment is a biconcave shape made of a soft synthetic resin material,
In FIG. 1, as shown in FIG. 1A, separate ones are pressed in the direction of the combination arrow as shown in FIG. 1B, that is, the soft lens 1 is pressed and deformed to be adsorbed as shown in FIG. In this way, a plano-concave lens as shown in FIG. 1C is formed.

For example, if a biconcave soft lens 1 made of a soft synthetic resin is adsorbed and fixed on the inner surface of protective glass for underwater glasses or ski goggles as shown in FIG. Even if you wear underwater glasses or goggles without wearing glasses, you can observe the outside without any inconvenience.

FIG. 2 is a view showing a second embodiment. Both the soft lens 1 and the plate-like body 2 made of glass or a hard plastic material have a meniscus lens shape, and as shown in FIG. Soft lens 1 on the convex side of 2 (eyeglass lens)
When the concave surface of the lens 1 is arranged and pressed from the direction of the arrow, the lens 1 is attracted to the lens 2 to form a meniscus-shaped negative lens as shown in FIG.

This embodiment shows that, for example, if the lens 1 is an eyeglass lens for myopia, a soft lens can be used for protection thereof.

FIG. 3 is a diagram showing a third embodiment. In this embodiment, the soft lens 1 has a shape in which a concave lens portion 1a and a convex lens portion 1b are integrated, and one side has one concave surface 1c.

The concave surface 1c side of this lens 1 is shown in FIG.
As shown in FIG. 3C, a magnifying glass having a different magnifying power can be formed by adsorbing to a transparent plate (plate-like body) 2 such as glass.

FIG. 4 shows a fourth embodiment, in which a plano-concave soft lens 1 is attached to a lens (plate-like body) 2 made of glass or hard plastic having a meniscus shape, as shown in FIG. 4 (B). The lens for myopia as shown in (C) is formed by arranging and adhering by pressing from the direction of the arrow.

In this embodiment, a sunglasses for nearsightedness can be formed by adsorbing a negative lens made of soft plastic on infrequent sunglasses. Further, it can be extremely easily changed to a polarizing glass having a high degree of adhesion by adsorbing it on a polarizing glass having a low degree or a glass for welding.

FIG. 5 is a cross-sectional view of Embodiment 5 of the present invention, in which a soft lens 1 made of a soft synthetic resin having a flat surface on both sides is arranged on the concave side of a negative lens 2 made of glass or hard plastic such as a lens for myopia. This is a negative lens that is pressed and adsorbed to form an integrated negative lens as shown in FIG. 5C, and has the same degree as the lens 2.

If this soft lens 1 is colored, it becomes a sunglasses with a high degree. What's more, you can make sunglasses with the same degree as the glasses you use. If a soft lens is used as a polarizing plate (polarizing glasses), it will have a certain degree of polarizing glasses.
Further, even a transparent resin protects the lens 2 and also protects the eyes in the event of an accident because it is soft.

FIG. 6 shows a sixth embodiment, in which a plate-like body 2 which is a lens made of glass or a hard plastic material, such as a spectacle lens, has a diameter smaller than that of the plate-like body 2. A soft lens of a diameter is adsorbed. As shown in the figure, the meniscus-shaped soft lens 1 having a small diameter is arranged on the concave side of the plate-like body 2 having a large diameter, and the concave surface is arranged on the concave side of the plate-like body 2 in the direction shown in the drawing, for example, near the lower end, and it is pressed. It is adsorbed on the plate-shaped body 2. As a result, a bifocal lens or a multifocal lens as shown in FIG. 5C can be obtained.

FIG. 7 is a sectional view of the seventh embodiment of the present invention.
Similar to the first embodiment, a soft biconcave lens is attracted to a plate-like body 2 made of glass or a hard plastic material having flat surfaces on both sides, and the soft lens is surrounded by a rim 3 as shown in FIG. First, the plurality of protrusions 4 are provided and the soft lens is adsorbed and integrated as shown in FIG. 7C in that a space is provided between the soft lens 1 and the plate-shaped body 2. It differs from the embodiment.

Like the soft lens of the seventh embodiment,
If the step portion 3 is provided on the edge and a plurality of minute projections 4 are provided, when the soft lens is adsorbed, a void is formed in the middle, and an air layer in this void provides a heat insulating effect and has an antifogging effect. become.

In the seventh embodiment, even if the lens 1 is made of a hard material and the edge 3 is made of a soft material, the same effect as that of the seventh embodiment can be obtained.

Similarly, it is conceivable to separate the lens portion and the edge 3. FIG. 9 is a view showing an eighth embodiment. 1 is a lens having a degree such as a spectacle lens, 2 is a transparent plate-like body such as goggles, and 5 is a holder corresponding to the edge 3 of the seventh embodiment. In this embodiment, the plate lenses 2 such as the prescription lens 1 and other lenses are made of a hard material, that is, glass or a hard synthetic resin material, and the holder 5 is made of a soft synthetic resin. Here, as shown in FIG. 9A, the lens 1,
The holder 5 and the plate-like body 2 are arranged in combination, and the holder 5 is pressed in the direction of the arrow to compress the holder 5 so that the air between the lens 1, the holder 5 and the plate-like body 2 escapes, thereby adsorbing the three members integrally The configuration is similar to that of the embodiment of FIG.

The shape of the holder 5 is not limited to a simple ring shape as shown in FIG. 10, but a holder 6 made of a ring-shaped soft material is integrally provided on a frame 6 as shown in FIG. Various modifications are possible.

Further, a ring-shaped holder made of a soft material is integrally formed inside the airtight frame of the underwater eyeglasses (goggles), which is made of soft material (two holders shown in FIG. One connected thing) is formed, and a prescription lens such as a lens for myopia is adsorbed to this to fix the prescription lens to the transparent plate-like body (transparent window) of the underwater glasses, and to It is also possible to wear glasses. When it is desired to use different materials for the frame and the holder, the frame and the holder may be molded separately and then the holder may be fixed to the frame.

As the material of the soft lens of each of the above embodiments, a rubber-like material having high elasticity and flexibility and high transparency is most suitable. For example, a soft silicone resin,
Vinyl chloride resin, urethane resin, etc. are considered.

[0029]

Since the soft lens of the present invention is made of a material which is easily deformed, the hard lens is adsorbed by a plate-like body (lens or a plate having both flat surfaces) made of glass or hard plastic. It is possible to adsorb the adsorbed lens without changing the degree of adhering or to a flat plate to give a certain degree of adhering, and it is possible to easily peel off the adsorbed lens.
Therefore, you can attach it to goggles or inexperienced sunglasses to wear the required glasses. It also protects the lens and eyes without changing the degree.
