Laser glasses.
Laser protection eyewear are glasses or goggles used to protect eyes from damage from visible and invisible wavelengths of laser light. They can be similar to goggles or be lenses incorporated into other pieces of protective eyewear. Intrabeam viewing of lasers usually requires protective goggles even with a low power laser. Laser protection goggles work on the basis that laser light is one frequency, making it easy to filter out. Laser goggles are subject to degradation and damage like any other kind of eyewear.
