What glasses are there on the market?

Common glasses on the market are divided into four categories, each with its own characteristics. Consumers can choose according to their own needs. Anti-blue light goggles category 1) 0-degree PerfectSight goggles have a cold brown frame, which is fashionable and anti-protective. It is suitable for office games and other scenes and can filter out 99% of harmful blue light. 2) CAPONI ultra-light rimless gold silk flat-light eyeglass frame weighs only 7 grams. The lens is transparent and stable against blue light, meeting the needs of frequent wear.

The common glasses on the market are mainly divided into four core categories: anti-blue light goggles, fashionable glasses, cheap high-quality frames and China famous brand glasses. Each type of glasses has significant differences in function positioning, design style, adaptation scene and price range. Consumers can make targeted choices in combination with their own use requirements (such as electronic equipment use time, wearing style, face characteristics, budget, etc.). The following is a detailed introduction to each category.

International brand ZEISS Growth Music: It adopts peripheral vision control technology, and the degree of the surrounding area of the lens is gradually changed. It is suitable for children under the age of 12 in development. The unit price is about 1,600 - 4,000 yuan. Heuer Xinlexue: The defocus signal pool is formed by 396 microlenses, and the prevention and control efficiency is about 59%. It is especially suitable for people with initial low myopia. The price ranges from 3,000 to 6,000 yuan.

Argon arc welding is the best glasses for eye protection

1. In argon arc welding operations, it is crucial to protect your eyes. It is necessary to protect yourself from strong light, ultraviolet/infrared radiation and spatters at the same time. The following are professional suggestions: ###Special welding mask Automatic dimming welding mask: The preferred equipment can automatically adjust the lens darkness (usually DIN9-13), and the reaction speed is ≤0.1 milliseconds. It is recommended to choose a design that covers the entire face., with neck protection.

2. Yes, glass flat glasses can prevent or reduce the radiation from welding arc to the glasses. I am also a welder. When I was an apprentice, I didn't wear glasses much, and my eyes often pierced. Later, I became accustomed to wearing flat-light glasses. Occasionally, I was caught by an arc light, and my eyes stopped hurting at night.

3. Core recommended goggles type UV protection welding goggles (argon arc welding/soldering universal model) This is the most suitable type of goggles for soldering. Although soldering does not produce a strong arc like electric welding, the solder melts. Ultraviolet rays and a small amount of infrared rays will be released, and splashing high-temperature tin beads may also hurt eyes.

What are the glasses that can see and prevent welding?

1. There are mainly the following types of glasses that can both see and protect against welding: Anti-glare eyewear These goggles are specially designed for welding and cutting operations, and their core function is to block strong light and ultraviolet rays. The arc light generated during the welding process contains a large amount of ultraviolet and infrared rays. If it is not effectively protected, it may cause electric ophthalmia (commonly known as "eye-piercing"), causing redness, swelling, pain and even loss of vision in the eyes.

2. According to our understanding, protective glasses suitable for spot welding can refer to these two models: UVEX Youvis 9301145 welding protective glasses. This is professional-grade eye protective equipment that can block more than 99% of ultraviolet and infrared rays and avoid arc radiation burns the eyes. At the same time, it also comes with an anti-glare function, which can weaken the stimulation of strong light and improve the clarity of vision and wearing comfort during operation.

3. Recommended automatic light-changing welding glasses: the protection is high. When positioning the welding joints, there is no need to lift and put down the black glass welding cap, making the operation more convenient.

What products do lenses belong to in electric welding

Welding lens materials need to have certain strength, considerable elasticity, and moderate rigidity. It is best to use reinforced PC lenses. There will be sparks when welders are working, so the materials used to make welding glasses cannot be flammable materials.

Welding protective lenses: Used to weaken the harm of ultraviolet, visible and infrared rays in the arc to the human eye. The old protective lenses are composed of filter glass grade 5 - 12 and white glass on the outside; the new ones are generally composed of filter lenses that can change light and adjust. They are mostly installed on the mask, and some are sold separately and can be replaced according to the size of the mask.

The manual arc welding process produces intense ultraviolet (UV), infrared (IR) and dazzling visible light. Handle-welded lenses are made of dark glass added with rare earth elements such as cerium to protect eyes by comprehensively absorbing and attenuating harmful radiation across a wide spectral range. Its protection level is expressed by Shade Number, such as the common number 9-13. The larger the number, the darker the lens, which is suitable for welding operations with higher current.

Ordinary sunglasses cannot be worn when welding, but protective welding glasses are required. Eye protection glasses for gas welding. The colorants used in this lens are mainly iron oxide, cobalt oxide, etc., which are yellow-green and can absorb all light waves with wavelengths below 500urn. The transmittance of visible light is below 1%, and only a small amount of infrared light can pass through. These glasses are specially used during gas welding operations.

What material is good for goggles

The selection of goggles material needs to be determined according to the usage scenarios and needs. Common recommended materials include polycarbonate (PC), glass, resin and TR90/polypropionate. Specific suggestions are as follows: Polycarbonate (PC) material: Sports and protection The preferred PC material has its core advantages of lightness, impact resistance, and ultraviolet resistance, and is suitable for sports scenes (such as basketball, cycling) and outdoor activities. Its impact resistance far exceeds that of glass, and it is not easy to break even if it is impacted by external force, and it is highly safe.

To sum up, from the perspective of durability, goggles made of polycarbonate (PC) are the first choice due to their high transparency, strong impact resistance, non-breakable, and stable chemical and physical properties. However, the specific material to choose still needs to be decided based on the use environment and needs.

The first choice for goggles is polycarbonate (PC), which combines impact resistance, lightness and durability. When selecting the material for goggles, you need to balance protection, comfort and use scenarios. If it is used daily for splash protection or sports protection, polycarbonate (PC) material performs the most balanced-it can withstand splatters of 120 meters per second in impact resistance tests, but it weighs 50% less than glass. Wear for a long time is not easy to fatigue.

What are the common problems when choosing protective glasses?

Protective glasses generally do not interfere with the gas mask, but usually cannot be used at the same time as a full-face mask. For a loosely fitted respirator mask, protective glasses can be worn inside the mask or hood.

Children's visual development: Especially for children, if you wear tinted film radiation-proof glasses, it may reduce the stimulation of light, which is not conducive to visual development. Individual differences: Different people have different eye conditions and needs, and not everyone is suitable for wearing a certain type of protective glasses. Excessive reliance: Neglect of daily protection: Wearing protective glasses cannot replace daily eye protection measures, such as reducing the time spent using electronic products and maintaining correct eye posture.

Precautions for the protection of prevention and control glasses in daily life are as follows: Wear and adjust the frame correctly: Ensure that the prevention and control glasses are comfortable to wear and fit the face. The legs of the glasses should not be too tight or too loose. They should generally be stable on the bridge of the nose and ears. It is advisable not to cause significant pressure on the skin. For example, if the legs of the glasses are too loose, the glasses will easily slide down, affecting the prevention and control effect; if they are too tight, they will cause discomfort and even cause headaches.

Appropriate size can ensure that the protective glasses have good tightness and will not shake or fall off during operation.
