Safety glasses serve as your first line of defense against flying debris and sparks. These are not your everyday eyeglasses; they are specially designed to offer both side and frontal protection. Often, they come with polycarbonate lenses that are scratch-resistant and can filter out 99% of harmful UV rays. When selecting safety glasses, ensure they meet or exceed the ANSI Z87.1 safety standard for optimal protection. You can read more about the ANSI standard on its Wikipedia page.

Face Shields

While safety glasses provide adequate eye protection, they don’t offer complete face coverage. That’s where face shields come in. A face shield is a clear visor that extends to cover the entire face, offering protection against flying debris, as well as harmful rays emitted during the cutting process. For plasma cutting, it’s advisable to use face shields in conjunction with safety glasses for maximum protection. Some face shields come with built-in UV/IR filters, providing an added layer of security against harmful radiation. To know more about the types of face shields and their applications, you can visit the Wikipedia page on face shields.
