Are Goggles Disposable?
1.Role of goggles
Avoid eye damage from light
Protective glasses are a kind of filter, which can absorb some wavelengths of light, so as to let other wavelengths of light pass through, so as to avoid damage to the eyes caused by radiation. Protective glasses are a kind of special glasses, which are designed to prevent radiation, chemical, mechanical and light damage of different wavelengths. It can also prevent eye damage from strong light sources, lasers, ultraviolet rays and rays.
Anti virus infection
The lens of goggles can isolate the virus from entering the eye conjunctiva. It is an important protective appliance to protect the eyes from virus infection during the high incidence of virus. General medical staff need to wear goggles for protection due to direct contact with patients to avoid virus infection.
Prevent sand and dust from entering eyes
Ordinary goggles can prevent foreign matters from entering the eyes. They are suitable for outdoor travel in the environment with large wind and sand. They can prevent wind and sand, pollen catkins, broken metal, sand and gravel debris, etc.
Protection against chemical injury
In the process of chemical experiment and chemical production, goggles are mainly used to prevent chemical damage to eyes caused by irritating or corrosive solution and smoke.
2.Material of medical goggles
Medical goggles are composed of lens and frame, and the material of frame has no special requirements. The lens can be made of polycarbonate, optical resin and polymethylmethacrylate, with unique optical crystal materials such as anti blue light, anti ultraviolet, anti optical radiation and impact resistance and exclusive special process research and development.
1.)Polycarbonate
Polycarbonate is called PC for short. At present, most goggles on the market are made of polycarbonate. Polycarbonate has the advantages of high transparency, good impact resistance, not easy to break, can withstand steam, cleaning agent, heating and high-dose radiation disinfection, and does not turn yellow and decline in physical properties.
2.) Optical resin
Optical resin refers to the synthetic resin used to glue optical parts in order to achieve some optical properties. Generally used in glasses, indoor lighting products, etc. The optical resin lens has the advantages of light weight, not easy to crack and strong fog resistance.
3.) Polymethylmethacrylate
Also known as plexiglass, which is often called acrylic. It has the advantages of good transparency, chemical stability, mechanical properties and weather resistance, easy dyeing, easy processing, beautiful appearance and so on.
3.Are goggles disposable
There are many types of goggles. Generally, medical goggles are disposable. In order to ensure the safety of medical goggles, clinical medical personnel must discard them after use. Generally, some goggles used in industry, such as tactical goggles, gas welding goggles, blue light goggles and other goggles, are not disposable and can be reused. At ordinary times, they only need to be cleaned and disinfected regularly.
4.How to choose medical goggles
1.) Choose goggles that meet or exceed the requirements of national standards.
2.)Select brands with the following marks, including La labor safety mark, QS quality mark, safety standard number, goggle model, production date, manufacturer's trademark and name.
3. )Understand the protection requirements, select the corresponding protection functions, and select goggles with good quality.
4.) On the premise of meeting the protection requirements, choose to wear comfortable goggles.
