Answer 1

Welders wear special glass goggles or face masks with glass windows to protect their eyes from ultraviolet rays.

Explanation:

Welders wear special glass goggles or face masks with glass windows to protect their eyes from the high amount of ultraviolet (UV) rays produced by welding arcs. These glass filters absorb the harmful UV radiation, which could otherwise cause “welder’s flash” or painful inflammation of the cornea.
