Description

Safety glasses

The invention relates to a safety goggle.

Safety glasses are safety aids that workers must wear when carrying out dangerous work. They can prevent liquids, artifacts, dust, etc. from harming the eyes of workers. For presbyopic workers, in general, in addition to wearing safety glasses, you also need to wear your own reading glasses in safety glasses. At this time, there are many inconveniences: when the external temperature is low, the gas exhaled by the worker himself (due to wearing the mask) will rise from the nose to the safety glasses, causing fogging of the reading glasses and affecting the operation; Safety glasses generally fit well with the skin around the eyes to form a tighter space, which protects the eyes in all directions. However, when wearing the reading glasses inside, the reading glasses are not easy to adjust to the proper position. The person feels extremely tired eyes.

In view of this, it is necessary to provide a safety goggle for a presbyopic wearer without the need to wear reading glasses.

A safety goggles having a frame and a pair of lenses, the frame having a pair of lens receiving portions, the pair of lenses being correspondingly received in the pair of lens receiving portions, each of the lenses comprising at least one progressive The at least one progressive surface includes a distance zone, a near zone, and a gradient gallery; the frame further includes a shield, and the shield extends from the lens receiving portion.

Compared with the prior art, the safety glasses of the technical solution can not only play a safety protection role, but also can be used for the correction of presbyopia without the need to wear the reading glasses, especially the correction of presbyopia in the middle and close distance, thereby reducing the eyeball. Fatigue.

Referring to FIG. 1 , a preferred embodiment of the present technical solution provides a safety goggle 1 that includes a frame 11 and a pair of lenses 13 .

The frame 11 includes a shield 112 for protecting the wearer's eyes and the area around the eyes.

When worn, the shield 112 completely conforms to the wearer's face or covers an area around the wearer's eye that includes the front side, the side, and the like.

Only the structure of the shield 112 is given in this embodiment. In other embodiments, the arrangement of the shield is not limited to the illustrated arrangement.

The frame 11 has a lens receiving portion 114, and the pair of lenses 13 are received in the pair of lens receiving portions 114. The safety goggles 1 have only one pair of lenses 13, ie no other lenses. The shield 112 is formed to extend from the lens receiving portion 114.

The lens receiving portion 114 can be a receiving frame, a carrier bracket or a bearing surface. In this embodiment, the lens receiving portion 114 is a receiving frame.

The lens 13 and the lens receiving portion 114 may be an integrally formed structure, or may be a structure that is joined together by other connecting members. The protective cover 112 may be integrally formed with the lens receiving portion 114 or may be separately fabricated and attached to the lens receiving portion 114.

Each of the lenses 13 includes an optical region 131.

In this embodiment, the optical area 131 corresponds to the actual visual area of the wearer.

In this embodiment, the optical region 131 is substantially circular, and the distance between the centers of the two optical regions 131 corresponds to the lay length of the wearer.

Within the corresponding optical zone 131, each of the lenses 13 includes opposing front and rear surfaces that are remote from the wearer's spectacles, the rear surface being adjacent to the wearer's spectacles. At least one of the front surface and the rear surface is a progressive surface.

In this embodiment, the front surface is a spherical surface, and the rear surface is a progressive surface.

Referring to FIG. 2 together, the progressive surface 14 includes a distance zone 141, a near zone 142, a gradient gallery 143, and a mixing zone 144.

The distance zone 141 is located at an upper position of the lens 13, the near zone 142 is located at a lower position of the lens 13, and the distance zone 141 and the near zone 142 are connected by a gradient gallery 143. The mixing zone 144 is a peripheral zone and contains surface astigmatism that creates blur and distortion and provides only minimal visual utility.

In the embodiment, the gradient gallery 143 is an eccentric double arc curved surface, which is an upper arc and a lower arc respectively, the upper arc corresponds to the far-use area 141, the lower arc corresponds to the near-use area 142, and the gradient gallery 143 and the far side The connecting portion of the area 141 and the near-use area 142 is a continuous curved shape, and the upper arc top and the lower arc are curved toward the inner side of the gradient gallery 143, and the lower arc is offset toward the bridge of the nose to form an eccentric double-arc curved surface.

In this embodiment, the diopter of the distance zone 141 may range from 0.00 degrees to -10.00 degrees (negative 10.00 degrees). Wherein, when the diopter of the distance zone 141 ranges from 0.00 degrees to -6.00 degrees, the refracting grading of the lens 13 in the distance zone 141 may be 0.25 degrees/stage. The diopter grading of the lens 13 in the distance zone 141 may be 0.50 degrees/grade when the diopter range of the distance zone 141 is between -6.50 degrees and -10.00 degrees.

In this embodiment, the diopter of the near zone 142 may range from 0.50 degrees to +5.00 degrees (plus 5.00 degrees). Wherein, the diopter grading of the lens 13 in the near zone 142 may be 0.25 degrees/stage.

The width of the gradient gallery 143 in each of the lenses 13 is a gradation interval.

Preferably, the width difference H between the widest portion and the narrowest portion of the gradient gallery 143 in the same lens 13 is no more than 5 mm.

In this embodiment, the width gradation interval of the gradation gallery 143 is preferably from 6 mm to 7 mm from the gradation interval to between 18 mm and 22 mm in the gradation interval. In other words, the narrowest portion of the gradient gallery 143 may have a width ranging from 6 mm to 18 mm, and the width of the gradient gallery 143 may be selected from the range of 7 mm to 22 mm at the widest point, and is in the same lens 13 The preferred range of the width difference H of the widest width of the gradient gallery 143 at the narrowest point is: 1 mm ≤ H ≤ 4 mm.

The safety goggles 1 of the technical solution can not only play a safety protection role, but also has a pair of lenses, that is, it can be used for the correction of presbyopia without the need to additionally wear presbyopic glasses, especially the middle and close distance presbyopia correction, compared with The prior art can reduce the fatigue of the eyeball; in addition, the surface setting of the optical region of the lens 13 of the safety goggles 1 of the present technical solution reduces the adjustment range of the lens to the eyeball, slows the eyeball fatigue, greatly increases the adjusted visual area, and utilizes the arc. The shape of the gradient corridor connects the far-reaching zone and the near-use zone, and the gentle transition is due to the movement of the eyeball. The visual receiving change is an arc-shaped change. After the main vision enters the far-use zone and the near-use zone, the side-side light vision is again By entering the corresponding viewing zone, a seamless visual transition effect can be achieved. Therefore, when the cross-viewing zone changes, the adjustment of the eyeball is small and gentle, and thus the fatigue of the eyeball can be reduced.

It is to be understood that a person skilled in the art can make various other changes and modifications in accordance with the technical concept of the present invention, and all such changes and modifications are intended to fall within the scope of the present invention.
