Description
【考案の詳細な説明】 〔産業上の利用分野〕 本考案は水中眼鏡、特に視力矯正が可能な水中眼鏡に関
するものである。[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.
従来、一般の水中眼鏡の前面ガラスには度が入っておら
ず、視力の弱い者には潜水中、周囲が良く見えない欠点
がある。これに対し、前面ガラスとして度付きレンズを
用いた水中眼鏡も市販されている。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.
ところが、水中眼鏡の前面ガラスは視野を確保するため
に大型ガラスが使用され、しかも耐圧性が要求されるた
め、度付きレンズを使用するとしても一般の眼鏡用レン
ズとは異なり、特別注文しなければならないため高価で
あり、しかも極度の近視や乱視の場合、使用者の視力に
正確に適合した度突きレンズが得にくい。また、度付き
の水中眼鏡は、そのレンズが表面に露出しているため、
水中眼鏡を誤って落としたりすると、高価なレンズが損
傷したり、破損する危険性が高い。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.
そこで、本考案の目的は、一般の眼鏡用レンズを用いて
正確に視力矯正ができ、かつレンズを損傷する危険性の
少ない安価な水中眼鏡を提供することにある。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.
上記目的を達成するために、本考案は、顔面に密着する

開口部の内周面に左右の視力矯正用レンズのうち内側縁
部を除く周縁部を着脱可能に嵌合保持するための嵌合溝
を形成したものである。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.
レンズ装着部の中央部に形成された開口部に左右のレン
ズを装着する場合には、レンズの内側縁部を手でつまん
で外側縁部から嵌合溝に嵌合すればよい。特に、開口部

の疲労を防止できる。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.

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.

されている。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.

てレンズ4,5を装着すればよく、装着性がよい。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.
