Eyeglass lens anti-fog structure

The present invention relates to a lens anti-fogging structure for a pair of glasses, and particularly relates to a channel for guiding the outside air to the inside of the lens at the frame and the nose pad to facilitate the fogging prevention of the lens.

According to the popularization of 3C products such as TV, computer and mobile phone, the ratio of myopia is increasing year by year. Modern people need to wear myopia glasses to correct vision. More and more people are prone to hyperopia, presbyopia, etc. Phenomenon, it is also necessary to wear corrections such as farsightedness and reading glasses. In addition to wearing splash goggles and sun, it is often necessary to prevent splashes, intrusion or ultraviolet rays from being damaged by foreign objects in construction sites or when riding locomotives and sports. Eye protection, etc. are protected by glasses.

However, when people wear glasses, eyeglass lenses often occur because when the inside and outside of the glasses are different, moisture is condensed on the lens, causing the lens to be blurred and fogged, which affects the user's line of sight clarity and activity safety. When fogging, although the glasses can be removed and wiped with a soft cloth or toilet paper, the glasses are frequently wiped, which causes inconvenience in use, especially when driving or exercising, because the glasses cannot be removed at will, so when the glasses are worn When fogging, it is more troublesome and troublesome for the user.

In addition, the frames of the existing glasses are mostly made by the factory uniform specifications. Therefore, the height position and angle of the nose pad are fixed, but the height and width of each nose are different, so that when the glasses are worn, the nose pads cannot be properly abutted. The user's nose position is such that when the user wears the glasses, the glasses fall, or the glasses are tilted, the lens focus is shifted, and the like, causing discomfort of the user wearing the glasses.

The reason is that this creator has made many of the above-mentioned shortcomings in view of the use of existing glasses. It has been assisted by many years of ingenuity in research and design experience and knowledge.

The present invention relates to a lens anti-fog structure for glasses, the main purpose of which is to provide a passage for guiding the outside air to the inside of the lens at the frame and the nose pad, so as to prevent fogging of the lens for defogging. structure.

In order to achieve the above-mentioned implementation objectives, the present author has developed a lens anti-fogging structure for the following glasses, which includes:

a frame, wherein the frame is provided with two lens assembly vertical portions, and the frame is respectively disposed at the left and right sides of the inner surface of the nose bridge portion, and corresponding first and second coupling blocks are respectively disposed, and the frame is located at the frame a concave portion is formed at a center of the inner surface of the beam portion above the nose portion, and the inner surface of the middle beam portion is respectively provided with a corresponding third joint block and a fourth joint block at the left and right sides of the concave portion, and The frame has a through hole extending through the front of the frame at the concave portion thereof;

a nose pad, wherein the nose pad comprises a transverse body, and the lateral body is integrally connected with two wings on two sides of the lower side thereof, and the nose pad and the front side of the lateral body are respectively formed with a first combination The groove, the second joint groove and the third joint groove respectively make the first joint block and the second joint block of the left and right sides of the nose bridge portion of the frame frame and the first joint groove of the nose pad of the nose pad respectively And the second joint groove is correspondingly combined, and the third joint block and the fourth joint block of the frame are combined with the third joint groove of the lateral body of the nose pad, and the nose pad is located at the front side of the horizontal body and the two wings. a concave portion is formed at the joint portion, and the concave portion of the nose pad corresponds to the position of the concave portion of the frame, and the concave portion of the nose pad is connected with the third joint groove, and the two wings are corresponding to the concave portion of the nose pad. Each of the positions is provided with a through hole such that the two through holes communicate with the concave portion.

The lens anti-fog structure of the lens as described above, wherein the nose pad is further provided with an air guiding block at a central upper edge of the third coupling groove corresponding to the through hole of the concave portion of the frame.

The anti-fogging structure of the lens of the above-mentioned lens, wherein the inner surface of the frame is formed with two linings which are tapered from the sides of the frame to the adjacent lens group, and A plurality of through holes are formed in the lining.

The anti-fogging structure of the lens of the above-mentioned lens, wherein the inner surface of the frame is formed with two linings which are tapered from the sides of the frame to the adjacent lens group, and A plurality of through holes are formed in the lining.

The anti-fogging structure of the lens of the lens as described above, wherein the first bonding block and the second bonding block of the frame are respectively convexly provided with flanges at both ends thereof, and the third bonding block of the frame and the third Each of the four joint blocks has a flange formed at a position opposite to the concave portion of the frame, and the first joint groove, the second joint groove and the third joint groove of the nose pad are respectively disposed a latching groove extending at both ends thereof, so that the two end flanges of the first joint block and the second joint block are respectively embedded in the embedded groove of the first joint groove and the second joint groove, and The third joint block and the fourth joint block are respectively embedded in the embedded groove of the two ends of the third joint groove.

Therefore, when the user moves, the outside air can flow into the inner surface of the frame through the through hole in the front of the frame, and then flows into the concave portion of the nose pad, and is continuously discharged through the through hole of the nose pad and the concave portion thereof to blow toward the hole. On the inner side of the lens, according to this, when the inside of the lens generates mist due to the temperature difference, the outside air is blown, so that the temperature inside and outside the lens is uniform, so that the lens is defogged, and the inner surface of the lens frame is lined at the corresponding portion of the lens group. The sheet is such that the outside air is blown to the inner side of the lens through the through hole of the lining, and the air blown to the inner side of the lens by the two wings of the nose pad is combined to achieve effective lens defogging effect.
