Safely View a Solar Eclipse. Our solar-eclipse glasses provide eclipse safety for viewing all solar eclipses. Eclipse glasses, and eclipse viewers, block out 100% of harmful ultra-violet rays, 100% of infrared, and 99.999% of intense visible light, protecting your eyes and letting you view these spectacular natural phenomena.
Safety glasses (spectacles) are commonly used as protection against impact and optical radiation. Tinted safety glasses used in torch soldering must have a shade number (1.5-3) on the lens, but do not provide adequate protection for gas or arc welding which need shades 4 or higher.
