Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to hydroscopic glasses, and more particularly to hydroscopic glasses capable of correcting vision.

[Conventional technology]

Conventionally, there is a drawback in that the front glass of general underwater glasses does not have a certain degree of power, and a person with weak eyesight cannot see the surroundings well while diving. On the other hand, underwater glasses using a prescription lens as a front glass are also commercially available.

[Problems to be solved by the device]

However, large glass is used for the front glass of the underwater glasses to secure the field of view, and pressure resistance is required, so even if a prescription lens is used, it must be specially ordered, unlike general lenses for glasses. It is expensive because it has to be done, and in the case of extreme myopia or astigmatism, it is difficult to obtain a striking lens that exactly matches the visual acuity of the user. In addition, since the lens of the prescription glasses is exposed on the surface,
There is a high risk that the expensive lens will be damaged or broken if the underwater glasses are accidentally dropped.

Therefore, an object of the present invention is to provide low-priced eyeglasses which can correct the visual acuity accurately by using a general eyeglass lens and have a low risk of damaging the lens.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention is a single-lens type underwater glasses in which a single transparent front glass is fixed to the front part of a cylindrical underwater glasses body made of an elastic body that comes into close contact with the face. In the inside of the portion where the front glass of the hydroscopic glasses body is fixed, a continuous wall-shaped lens mounting portion substantially parallel to the front glass is integrally provided, and left and right vision correction lenses are provided in the center of the lens mounting portion. One continuous opening having a contour that substantially corresponds to the outer shape of the lens is provided, and the inner peripheral surface of the opening is detachably fitted to the peripheral portions of the left and right vision correction lenses excluding the inner edge portion. A fitting groove for holding is formed.

[Action]

When the left and right lenses are mounted in the opening formed in the center of the lens mounting portion, the inner edge of the lens may be pinched by hand and fitted into the fitting groove from the outer edge. In particular, since the opening communicates with the central portion, the inner edge of the lens is exposed, and the inner edge of the lens can be easily picked by hand when the lens is attached and detached. Further, since the peripheral edge portion of the lens excluding the inner edge portion is fitted and held in the fitting groove of the lens mounting portion, the lens does not shift in the vertical and horizontal directions in the mounted state. This means that the center of the optical axis of the eyeball of the user and the center of the optical axis of the lens can always be made to coincide with each other even if the lens is repeatedly attached and detached, and it is possible to prevent distortion of the field of vision and fatigue of the eyes.

〔Example〕

FIGS. 1 and 2 show an example of the single-lens type underwater glasses according to the present invention. The front surface portion 11 of the tubular underwater glasses body 1 made of an elastic body such as neoprene or silicone rubber has excellent pressure resistance. A piece of transparent front glass 2 made of hardened glass (TEMPERED GLASS) is attached, and a reinforcing frame 3 prevents the glass from falling off. The rear surface portion 12 of the water glasses main body 1 is formed into a shape that can be brought into close contact with the face, and a nose knob portion 13 into which the nose portion fits is formed in the lower portion of the rear surface portion 12. In addition, holes 14 for inserting both ends of a rubber band (not shown) are formed in both outer side portions of the water glasses main body 1.

A wall-shaped lens mounting portion 15 that is continuous and substantially parallel to the front glass 2 is integrally formed inside the underwater glasses body 1.
A continuous opening 16 having a contour substantially corresponding to the outer shape of the left and right vision correcting lenses 4 and 5 is formed at the center of the lens mounting portion 15, and the inner peripheral surface of the opening 16 is formed. A fitting groove 17 is formed in which the peripheral edges of the lenses 4 and 5 except the inner edges are fitted. The lens mounting part 15
A portion 19 corresponding to the nose knob portion 13 is cut out so as not to interfere with the nose portion of the wearer. A protrusion 18 is formed at the center of the upper portion of the opening 16 to prevent the lenses 4 and 5 fitted in the fitting groove 17 from shifting in the left-right direction.

When the lenses 4 and 5 are attached to the fitting groove 17 of the main body 1 in the hydroscopic glasses having the above configuration, the distance between the viewpoints of the eyes of the user and the distance between the center points of the lenses 4 and 5 are adjusted so that the lenses The outer shapes of 4 and 5 are processed according to the opening 16. This processing can be easily performed at a general eyeglass store. Then, when the processed lenses 4 and 5 are forcibly fitted into the fitting groove 17, the main body 1 is an elastic body, so that the lenses 4 and 5 can be easily mounted without being damaged, and after the mounting, the fitting is performed. The fitting groove 17 and the projection 18 formed at the center of the upper portion of the opening 16 allow the lenses 4 and 5 to be stably held without being displaced in the vertical and horizontal directions. When the lenses 4 and 5 are mounted, a space including the cutout portion 19 is provided at the center of the opening 16 of the lens mounting portion 15. Therefore, a finger is inserted through the space to mount the lenses 4 and 5. It only needs to be attached and has good wearability.

As described above, if the lenses 4 and 5 are attached and diving is performed using the underwater glasses, the field of vision becomes clear even for a person with a weak naked eye,
You can dive without worry. At this time, since the nose of the wearer corresponds to the notch 19 of the lens mounting part 15, the nose does not interfere with the lens mounting part 15. Further, when the front glass 2 or the lenses 4 and 5 are soiled, the dirt can be easily wiped off by inserting the lenses 4 and 5 from the lens mounting portion 15 by inserting the lenses 4 and 5 from the notches 19 of the lens mounting portion 15. In addition to these, the following effects can be expected for the hydroscopic glasses.

(A) The lenses 4 and 5 are smaller in shape than the front glass 2, but since the lenses 4 and 5 are located near the eyes of the user, they do not narrow the field of view as shown in FIG.

(B) Since the lenses 4 and 5 are not subjected to water pressure at all, a lens that has a low strength like a plastic lens but is hard to break and is inexpensive can be used.

(C) The conventional hydroscopic glasses using the prescription lens can be applied only to the twin-lens type in which the front glass is divided into left and right, but the present invention can be applied to the single-lens type, and the single-lens type has a wide field of view.
This is advantageous because it is easy to attach the lenses 4 and 5.

(D) Since the outer surfaces of the lenses 4 and 5 are protected by the front glass 2, even if the main body 1 is accidentally dropped, the lenses 4 and 5 are protected.
5 is not easily scratched or cracked. Therefore, it can be used for a long period of time.

(E) Since the shapes and sizes of the lenses 4 and 5 can be the same as those of general eyeglasses, it is not necessary to use a special hardened glass unlike the conventional ones, and even if it is extremely myopia, even if it is extremely myopia, the eyesight is most Suitable lenses can be easily procured at eyewear stores.

(F) By forming the lens mounting portion 15 into a continuous wall shape, the underwater spectacle body 1 can be reinforced from the inside, the bending when deep diving can be prevented, and the load applied to the lenses 4 and 5 can be reduced.

(G) The visual axis correcting lens always has the optical axis center, and if the optical axis center and the optical axis center of the eyeball deviate, not only the distortion of the visual field but also the eye fatigue is caused. On the other hand, in the present invention, since the fitting groove 17 for fitting and holding the peripheral portions of the lenses 4 and 5 is formed on the inner peripheral surface of the lens mounting portion 15, the lenses 4 and 5 are always stably held at a fixed position. It is possible and there is no displacement. Therefore, there is no deviation of the optical axis, and eye fatigue can be prevented.

(H) It is difficult to attach and detach the lenses 4 and 5 when the hands are wet, but the inner edge portions of the lenses 4 and 5 are exposed even in the attached state. It can be easily attached to and detached from the lens mount 15. Even if the lenses 4 and 5 are repeatedly attached and detached, the optical axis is not displaced.

[Effect of device]

As is apparent from the above description, according to the present invention, the lens mounting portion having the fitting groove for detachably mounting the left and right vision correcting lenses inside the portion where the front glass of the underwater glasses body is fixed. Since it is integrally provided, the eyesight can be corrected at low cost by using a general eyeglass lens.

Further, since the peripheral portion of the lens is stably held at a fixed position by the fitting groove, there is no deviation of the optical axis, and there is an effect that distortion of the visual field and eye fatigue can be prevented.

Further, since the opening of the lens mounting portion communicates with the central portion, the inner edge of the lens is exposed even in the mounted state, and the lens can be easily attached to and detached from the lens mounting portion by grasping the exposed portion.
