Description

Industrial corrective eyewear

This invention is about an industrial eyeglass structure with a relatively larger effective visual range.

At present, in order to protect the eyes of workers when welding, grinding or cutting, they will wear goggles to avoid being hurt by foreign objects or flying debris. Although goggles can protect workers' eyes from being hurt, due to the long-term use of 3C products or the increase in age, modern people's vision deteriorates, and almost all of them will have symptoms such as myopia, presbyopia or hyperopia. Therefore, they need to wear corrective glasses in daily life. When wearing goggles at work, wearing two pairs of glasses at the same time will cause inconvenience at work and become troublesome.

Therefore, there is a new patent case No. M479737 "Lens structure with corrective vision" announced on June 11, 2014 in the Republic of China. It is disclosed that: it includes a plano lens area and an optical lens area, and when the lens is cut and installed in the lens frame, the optical lens area is located above the plano lens area, and at the same time, the optical lens area corresponds to the position of the upward line of sight of the human face; accordingly, it can provide the demander with good vision in the upward or normal line of sight. The optical lens area corresponds to the position 0~10mm directly above the direct line of sight of the eye, the diameter range of the optical lens area is 5~40mm, and the optical lens area is a concave lens or a convex lens.

Since the diameter of the optical lens area of the lens of the prior patent is only 5-40mm, the effective visual range of the worker's eyes is too small when working, so he often needs to lower his head to see the working range clearly. In particular, once there are foreign objects or flying debris flying outside the optical lens area, it is difficult to respond quickly and effectively, making the worker vulnerable to injury.

There is also a new patent case No. M554782 for "goggles with optical power" announced on February 1, 2018. It discloses that the goggles are provided with two optical lens areas and goggles area. The optical lens area can be matched with the power required by the user. When the goggles are cut and assembled in the frame, they can be worn by the user, thereby providing a more practical and convenient goggles with optical power. The optical power area of the goggles is set at the position of the user's eyes, and the optical power area of the goggles can be a concave lens or a convex lens.

Since the optical power area of the goggles in the patent application does not clearly define the diameter range, but only generally defines it at the position of the user's eyes, the effective visual range of the worker's eyes is too small, and the worker cannot clearly see other objects in the working range, and needs to lower his head to see the working range clearly. Moreover, when there are foreign objects or flying debris in the area outside the optical lens area, it is difficult to respond quickly and effectively, making the worker vulnerable to injury, so it is not ideal in use.

Therefore, in view of the fact that the current industrial spectacles with corrective lenses have the above-mentioned shortcomings. Therefore, this invention provides an industrial corrective spectacles, comprising: a frame, provided with two lens combining parts, a nose pad is provided between the two lens combining parts, and a lens foot is provided on both sides of the frame; two lenses are fixed to the two lens combining parts after cutting, and the two lenses have a lens surface respectively; two vision correction areas are integrally formed and combined with the two lenses, and the areas of the two vision correction areas are respectively between 1/4 and 3/4 of the total area of the two lenses, and the two vision correction areas are configured as a convex lens or a concave lens, and the refractive power of the lens is between 8D and 10D.

The vision correction zone is defined as a first direction close to the nose pad and a second direction away from the nose pad. The length of the vision correction zone along the lens surface in the first direction and the second direction is between 32 mm and 48 mm.

The vision correction zone is defined as a third direction facing upward, and a fourth direction facing downward. The width of the vision correction zone along the lens surface in the third direction and the fourth direction is between 32 mm and 49 mm.

The diopter of the above lens is 9D.

Each step of the above diopter is 0.25D.

Each step of the above diopter is 0.5D.

According to the above technical features, it has the following advantages:

1. Glasses can be worn on the worker's face to protect the worker's eyes from being injured by foreign objects or flying debris when performing welding, grinding or cutting.

2. The area of the vision correction zone is between 1/4 and 3/4 of the total area of the lens, making the effective visual range of the lens relatively larger. Therefore, workers can clearly see a larger working range without lowering their heads when working. If there are foreign objects or flying debris in the area outside the vision correction zone, the workers can also see it early and respond quickly and effectively to avoid eye damage.

3. The vision correction area is designed as a convex lens or a concave lens structure. Therefore, the vision correction area can be used to assist in correcting the worker's myopia, hyperopia or presbyopia. There is no need to wear myopia glasses, hyperopia glasses or presbyopia glasses separately, which can make the vision clearer and help the work go smoothly.

4. Since workers only need to wear industrial glasses with vision correction zones, and do not need to wear two pairs of glasses at the same time, the weight on the face can be reduced, and it will not affect the vision at work, nor cause any hindrance, making work easier and more convenient.

6. Since the vision correction area is integrally formed and combined with the lens, thereby manufacturing an industrial goggle structure, the manufacturing cost is quite low, and it can be used as a disposable industrial corrective spectacles.

In the following embodiments of the present invention, if directional terms such as left, right, front, back, up, and down are mentioned, they are based on the various directions of the worker after the glasses are worn on the worker's face. The directional terms are only for the convenience of explaining the embodiments of the present invention and do not limit the spatial form of the present invention.

Please refer to the first and second figures, the present invention comprises: a frame 1, two lenses 2 and two vision correction areas 3, wherein:

A frame 1 is provided with two lens joints 11 opposite to each other. A nose pad 12 is provided between the two lens joints 11 of the frame 1, and a temple 13 is provided on both sides of the frame 1.

The two lenses 2 can be cut into various shapes to match the different styles of the frame 1. After cutting, the two lenses 2 are fixed to the two lens joints 11 of the frame 1. The surface of the lens 2 is formed with a curved lens surface 21. The refractive power (curvature) of the lens surface 21 of the lens 2 is between 8D and 10D, which can meet the needs of industrial eyeglasses. The best refractive power of the lens 2 is 9D, and each level of the refractive power is 0.25D or 0.5D.

The two vision correction areas 3 are integrally formed and bonded to the two lenses 2. The area of the vision correction area 3 is between 1/4 and 3/4 of the total area of the lens 2. The vision correction area 3 is configured as a convex lens or a concave lens. The direction of the vision correction zone 3 close to the nose pad 12 of the frame 1 is defined as a first direction X1, the direction of the vision correction zone 3 away from the nose pad 12 of the frame 1 is defined as a second direction X2, the upward direction of the vision correction zone 3 is defined as a third direction X3, and the downward direction of the vision correction zone 3 is defined as a fourth direction X4. A length A of the vision correction zone 3 along the lens surface 21 in the first direction X1 and the second direction X2 is between 32 mm and 48 mm, and a width B of the vision correction zone 3 along the lens surface 21 in the third direction X3 and the fourth direction X4 is between 32 mm and 49 mm.

When worn, as shown in the first, second and third figures, the industrial corrective glasses can be worn on the face of a worker C to protect the eyes of the worker C from being injured by foreign objects or flying debris when the worker C is welding, grinding or cutting. The area of the vision correction zone 3 occupies 1/4 to 3/4 of the total area of the lens 2, so that the effective visual range of the lens 2 becomes relatively larger, so the worker C does not need to lower his head at any time when working, and can clearly see a larger working range. If there are foreign objects or flying debris splashing outside the vision correction area 3, or if there are other emergencies, the worker C can see them early because the visual range becomes larger, and can respond quickly and effectively to avoid injury to the worker C. In addition, the vision correction area 3 is configured as a convex lens or a concave lens structure, so the vision correction area 3 can assist in correcting the worker C's myopia, hyperopia or presbyopia. When working, there is no need to wear myopia glasses, hyperopia glasses or presbyopia glasses, which can make the vision clearer and help the work go smoothly. At the same time, the worker C does not need to wear two pairs of glasses at the same time, so the weight on the face can be reduced, and it will not affect the vision during work, nor will it cause any hindrance, which can make work easier and more convenient, and help improve work efficiency.

Since the vision correction area 3 is integrally formed and combined with the lens 2, and thus an industrial goggles structure is manufactured, the overall manufacturing cost is quite low, so it can be used as a disposable industrial corrective eyewear. If the eyewear is damaged, it can be discarded and replaced with a new one. In addition, since the vision correction area 3 occupies a relatively large area of the lens 2, the effective visual range of the lens 2 is relatively large, so the worker C does not need to lower his head to see the surrounding working range clearly, and even looking up, down, left or right, he can see the entire working range clearly, so that the worker C can wear and use it conveniently.
