Arc Eye (Welders Flash)

Arc-eye, also known as welder’s flash, is an inflammation of the cornea and is a result of ultraviolet (UV) radiation released by a welding arc.

Often, the symptoms of arc-eye do not appear immediately. Instead, they will develop over a period of a few hours. Therefore, anyone suffering may be unaware for several hours after exposure.

As the most common source of ocular flash burn, it is important to take adequate precautions to protect the eyes of those working with, or around, welding activities which have an exposed arc.

Two documents are attached:

  1. Explains what Arc Eye is and can be used where details of how to protect people is required.
  2. This document is intended to dispel the myth that circulates approximately every 5 years, that arc welding can cause contact lenses to adhere to the eye!
