Protective glasses are glasses that play a special role. Different glasses are used in different occasions. There are many kinds of protective glasses, such as dustproof glasses, impact-proof glasses, anti-chemical glasses, and anti-radiation glasses. Protective glasses, also known as protective eyewear, are divided into safety glasses and protective masks. They are mainly used to protect the eyes and face from electromagnetic radiation such as ultraviolet rays, infrared rays and microwaves, dust, smoke, metal and gravel debris and chemical solutions. Sputtering damage.

Safety glasses role

1. Anti-solid debris is mainly used to prevent mechanical damage to the eyes, such as metal or gravel debris. Spectacle lenses and spectacle frames should be structurally strong and resistant to impact. Frames are covered around the edges and there should be ventilation holes. Protective glasses can use tempered glass, glue glass or copper mesh protective glasses.

2. Anti-chemical fluid is mainly used to prevent chemical damage to the eyes from irritating or corrosive solutions. Ordinary flat optics can be used, and the frame should be covered to prevent splashing. Usually used in laboratories, hospitals and other places, general medical glasses can be used universally.

There are many types of protective glasses for safety glasses, including dustproof glasses, anti-impact glasses, anti-chemical glasses, and anti-radiation glasses. The first three kinds of glasses look like lenses are colorless glass, but in fact due to different protective effects, the characteristics of the lens are significantly different.

Workers engaged in industrial production are required to wear glasses. These glasses are not used for decoration and fashion, but are used to protect the eyes from harmful factors. Therefore, these glasses are called safety glasses.

Arc radiation

Workers engaged in welding, gas welding, steel making and glass blowing should wear anti-arc radiation glasses. However, the color of the lenses of the anti-arc radiation glasses is deep and shallow, which is designed according to different requirements. The choice should be properly selected according to the strength of the arc during operation. The arc light is strong and the color is dark; otherwise, light colored lenses should be selected. If the arc light wears a light-colored protective goggles, part of the infrared rays will stimulate and damage the eyes through the lens, and will suffer from occupational cataracts in the long term. On the other hand, if the arc is weak and the dark safety glasses are worn for a long time, the vision will be greatly reduced. Dust-proof glasses are used in a dusty environment. Generally, the fastness of the lens is not high. Regardless of the eye mask type or flat mirror type, general flat glass lenses are used.

Shockproof

Anti-impact eyeglasses are used to prevent small particles from flying through the eye. The lenses require impact resistance. For example, laver, sander and mason should wear anti-impact glasses. If these workers wear ordinary dust-proof glasses, then the iron sand When smashed with flying stones, the eyes will suffer more damage. Anti-chemical eyeglass lens anti-acid, corrosion resistance, which is not available in other glasses. Therefore, every worker who needs to wear protective goggles should understand the harmful factors of his operating environment and wear appropriate safety glasses.

Safety glasses features

1. Select goggles to use products that have passed inspection by product inspection agencies;

2, the width and size of the goggles should be suitable for the user's face;

3, rough lens wear, frame damage will affect the operator's vision, should be promptly exchanged;

4. Goggles should be used by professionals to prevent eye infections;

5, welding goggles filter and protective film to be selected and replaced according to the requirements of the operation;

6, to prevent heavy pressure drop, to prevent the hard object friction lens and mask.

Safety glasses cleaning and maintenance

First, the placement method If it is a temporary placement of glasses, please put the convex surface of the glasses, if placed on the convex face down glasses, will wear lenses.

Second, the lens cleaning method Use a special clean lens cloth, be sure to use your hand to hold the mirror side of the mirror side of the wire, gently wipe the lens. Avoid overstressing the frame or lens.

Please avoid contact with corrosive articles such as insect repellent, toilet articles, cosmetics, hair spray, and medicines when it is stored, otherwise it will cause deterioration of lenses and frames, deterioration, and discoloration.

5. When the glasses are deformed, the frames will be deformed and the nose or ears will be burdened. The lenses are also easy to loosen. It is advisable to go to the specialty store for regular adjustments. Prohibition: Do not use the resin lens when it is in violent motion.

It is recommended not to use lenses that have scratches, stains, cracks, etc., as this may cause unclear viewing of the light due to scattered light and cause vision loss.

Six, please do not look directly at the sun Even if the lens has a dark shade of color, do not look directly at the sun or strong light, otherwise it will hurt the eyes. Please be completely accustomed to wearing glasses to see things before driving and operating the lens prism relationship, it is difficult to grasp the sense of distance just purchased glasses, do not completely before driving and operating. Do not place the lens at high temperatures (above 60°C) for a long period of time. The lens may be deformed or cracks may form on the surface of the film. Do not place it in direct sunlight or at a high temperature in the front window of the cab.

7. If the lens gets wet, wipe it dry. If it gets dry naturally, the scale will become stained and it will be difficult to wipe it clean. Wash traces of sweat, cosmetics, and wipe dry.

5, the frame is not tight or loose screws, should be adjusted in time.

6. The coated lens has high definition and cannot touch organic solvent, oil, sweat acid, high temperature, chemicals and hard objects, otherwise it will damage the lens film and affect the clarity and appearance.

7. After using the glasses every day, please rinse with clean water and wipe the water with a special wiper to extend the life of the glasses.
