Description

Anti-reflective protective glasses

technical field

The present invention generally relates to the technical field of protective glasses, and particularly to anti-reflective protective glasses.

Background technique

Protective glasses are protective glasses that can protect the user's glasses. People need to wear protective glasses when they need to protect the eyes to avoid injury to the glasses. In some special occasions, the lenses that require protective glasses cannot have strong reflections. For example, when military and police personnel wear protective glasses in a hidden state, the reflection of the lenses can easily reveal the position of the personnel.

At present, the commonly used measure to reduce the reflection of the lens is to coat the surface of the lens with an anti-reflection coating. Although the anti-reflection coating can reduce the reflectivity, there will still be dazzling reflections, especially in the sun.

SUMMARY OF THE INVENTION

The object of the present invention is to provide a kind of anti-reflection protective glasses, the lens of the protective glasses includes a layer of a porous film covering the mirror and the outer surface of the mirror (relative to the wearer's glasses), through the porous pore diameter of the porous film and Spacing design, blocking the reflection path of light entering the lens, to achieve the effect of reducing the reflection phenomenon.

The technical solution of the present invention is to provide anti-reflection protective glasses, the lenses of the protective glasses include a mirror forming and a blocking porous film, and the blocking porous film covers the mirror forming surface and covers the protective glasses. A surface on the side away from the wearer's eyes when worn.

The lens formed by the mirror forming and blocking porous film of the present invention can not only effectively see objects when wearing glasses, but also can effectively block the reflected light on the mirror forming lens and reduce or eliminate the reflected light.

Further, through holes are uniformly distributed on the above-mentioned blocking porous membrane, the diameter of the through holes is Φ1mm-Φ3mm, and the hole spacing is 4mm-10mm.

The arrangement of the hole diameter and spacing enables the sidewall of the hole to effectively block the optical path of the mirror-reflected light, thereby reducing or eliminating the reflection.

Further, the edges of the contact surfaces of the mirror-forming and blocking porous membranes are respectively provided with holes and bumps matching the holes, so as to realize the connection between the two.

The tight fit between the holes and the bumps can effectively fix the blocking porous membrane on the outer surface of the mirror.

Further, the above-mentioned blocking porous film thermoplastic organic polymer material film, thermosetting organic polymer material film or metal material film.

The surface of the blocking porous membrane away from the contact surface with the mirror is a frosted surface. The frosted surface is to prevent strong reflection when the film itself is irradiated by light.

Further, the protective glasses of the present invention also include a mirror frame, a powerless ventilator and a mirror strap; the mirror frame is a mouth-shaped enclosure, and the peripheral shape of the enclosure close to the wearer's face is a lower edge with a concave arc. The frame, the edge shape of the frame is matched with the eye circumference of the human body to closely fit the eye circumference of the human body, and the concave arc is used to realize the fitting of the frame and the nose bridge of the wearer when wearing; the enclosure is far away from the wearer One side of the face is used to install and fix the lens; the side wall of the enclosure is perpendicular to the lens; the unpowered ventilator is arranged on the outside of the side wall of the enclosure opposite to the side wall of the enclosure where the concave arc is located, and is passed through the side wall of the enclosure. The side wall is communicated with the interior of the enclosure of the spectacle frame for extracting air in the enclosure of the spectacle frame when wearing; the spectacle strap is connected to both sides of the spectacle frame for wearing.

Further, the thickness of the blocking porous membrane is 0.2 mm to 2 mm.

Further, the above-mentioned mirror is made of one or more materials such as CR39 resin, polycarbonate, glass, or polyurethane, and the thickness thereof is 0.5 mm to 4.0 mm.

Compared with the prior art, the present invention has the following beneficial effects:

1) The blocking porous film on the outer surface of the mirror can ensure that the visual ability of personnel is not greatly affected when wearing protective glasses. The hole wall on the porous film can block the reflection path of the reflected light on the surface of the lens and reduce the reflection of the lens. .

2) The prior art mainly coats a layer of anti-reflection film on the surface of the mirror, so that when the light is irradiated on the surface of the mirror, the reflected light is reduced by increasing the transmitted light. This method needs to change the performance of the mirror surface, increasing the The complexity and difficulty of the process also reduces the yield of the mirror. In the present application, on the premise of not changing the existing mirror-forming performance and process, a blocking porous film is installed on the mirror-forming surface to block the optical path of light reflected on the lens surface to reduce or eliminate the phenomenon of reflection. Install the blocking porous film where it is necessary to reduce reflection, and remove it when it is not needed.

In the present invention, a blocking porous film is designed on the outer surface of the mirror, and a large number of pores on the blocking porous film can ensure that the visual ability of personnel is not greatly affected when wearing protective glasses, because the hole wall can block the reflected light on the surface of the lens the reflection path to reduce the reflection of the lens. The invention does not increase the process cost of the protective glasses and is flexible in use.
