Exposure of the eyes to welding arc light can cause photokeratoconjunctivitis (also known as “welder’s flash” or “arc eye”). There are no particularly effective home remedies for this condition. If inflammatory symptoms occur at night at home, artificial tears—commonly available over-the-counter—can be instilled into the affected eye(s) to significantly alleviate pain and foreign-body sensation. Artificial tears also support the repair of corneal and conjunctival epithelial cells; therefore, using them provides symptomatic relief. Crucially, avoid touching or rubbing the eyes, as irritation may trigger excessive tearing. Do not wipe or rub the eyes with tissues or towels. Prompt medical evaluation is essential: visit a hospital for a thorough ophthalmic examination. In most cases, damage caused by photokeratoconjunctivitis resolves spontaneously within 2–3 days.
