When using protective glasses, the glasses we choose must be products that have passed the inspection of the product inspection agency. The width and size of the glasses should fit the shape of the wearer's face. Remove the glasses with both hands and hold them gently, with the convex side of the lens facing the lens if temporary. These are some places that we usually need to pay attention to when using it, so what other precautions should we take? Let us continue to look down.
When not wearing protective glasses, please wrap them in glasses cloth and put them in the glasses case. When storing, do not use insect repellants, toilet cleaners, cosmetics, hairspray, medicines, etc. Do not touch corrosive substances. Frame deterioration, deformation, fading. If the lens is rough and worn, the frame is deformed or damaged, the screws are loose, the lens is easy to loosen, and the frame is not tight, it should be adjusted in time. Protective glasses If the above conditions occur, the deformation of the frame will cause a load on the nose or ears and affect the user's vision. They should be replaced in time. It is recommended to go to a professional store for plastic adjustment. The coated lenses of protective glasses have high clarity, and cannot be exposed to organic solvents, oil, sweat acid, high temperature, chemicals and hard objects, otherwise the lens film will be easily damaged, affecting the clarity and appearance.
To prevent protective glasses from scratches, stains, cracks, etc. It is not recommended to use the lenses you find with them, or the light will spread out and not make everything clear leading to vision loss. Do not place it in high temperature (above 60°C) for a long time. High temperature can easily cause lens deformation or surface film cracking. Do not place it in direct sunlight or a high temperature place such as a windshield.
Safety glasses should have metal frames protected from chemicals to prevent coating peeling and discoloration. Avoid heavy falling and heavy pressure, and prevent hard objects from rubbing the lens and mask. Use a clean special lens cloth, be sure to hold the edge of the frame on the side of the mirror with your hand, and wipe the lens gently. Avoid damaging frames or lenses with excessive force. Dry-wiping lenses are easy to scratch. It is recommended to rinse them with clean water first, then dry them with paper towels, and then dry them with special glasses cloth.

When the lenses of the protective glasses are exposed to rain or sweat, please wipe them clean with a lens cloth in one direction immediately. When wearing progressive multi-focal lenses, try not to use the edge of the lens to look at objects, because there is a sense of distortion and blur, and use the bottom of the lens to look at close-ups. The way to adapt is indoors. Then outdoors. The filter layer and protective layer of welding goggles should be selected and replaced according to the specified process requirements. Due to the prismatic nature of the lenses, please do not drive or operate until you are used to seeing in the glasses. It is difficult to grasp the sense of distance with new glasses. Do not drive or operate without fully seeing.
