Description

An electric heating type waterproof fog glasses

technical field

Background technique

With the development of science and technology, people's eye intensity has increased, and the protection awareness of glasses has become stronger and stronger. Glasses such as myopia glasses, sunglasses and diving glasses are also more and more widely used in people's daily life. There are four types of glasses for vision correction: nearsightedness and farsightedness, reading glasses and astigmatism glasses. In terms of the function of the lens, it can adjust the light entering the glasses and protect the eyesight; the spectacle frame and the spectacle frame play the role of support, and also have the effect of beauty and decoration. Wearing glasses has a certain protective and decorative effect, but sometimes it also brings inconvenience. When a person wearing glasses enters a high temperature environment from a low temperature environment or in rainy and snowy weather, the water molecules in the air liquefy and adhere to the outer surface of the lens, which is likely to produce water mist, which will block the vision and cause inconvenience.

The existing anti-fogging methods usually use anti-fogging sprays to treat the lenses or paste anti-fogging films, but this method is extremely inconvenient and will cause certain damage to the lenses. The effect is not obvious or even invalid. Another type of electric heating anti-fogging glass lens uses electric heating to evaporate water, but it will leave water stains on the surface of the lens. Other anti-fogging safety anti-fogging mirrors use the button to manually drive the brush head to remove the fog, but the complex structure is inconvenient to control and is not suitable for wearing.

Therefore, the present invention provides an electric heating type fog-proof glasses to effectively remove the water mist on the glasses lenses.

Detailed ways

The present invention will be described in detail below with reference to specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that, for those skilled in the art, several changes and improvements can be made without departing from the inventive concept. These all belong to the protection scope of the present invention.

The present invention provides electric heating type waterproof fog glasses. As shown in FIG. 1 , the waterproof fog glasses in this embodiment include a frame 1, a frame 2 and a lens 3. The frame 1 and the frame 2 are rotatably connected, and the lens 3 is fixed on the mirror frame 2; after the mirror frame 1, the mirror frame 2 and the lens 3 are connected, a symmetrical structure is formed.
