What initial treatment should be given to a patient exposed to ultraviolet light while welding?

The initial treatment for a patient exposed to ultraviolet light while welding should involve protecting the eyes from further damage. Covering the eyes with sterile, moist dressings helps to shield the damaged cornea from additional exposure to light and irritants, which can prevent exacerbating the injury. In instances of ultraviolet light exposure, such as from welding, the corneal surface can become inflamed or burned, leading to significant discomfort and potential complications.

Moist dressings provide a soothing effect and may help with hydration of the damaged tissues, which is important for healing. This approach can also reduce the risk of infection and further irritation while definitive medical treatment is obtained. Immediate eye irrigation or other methods might complicate the situation or be contraindicated in certain cases of corneal injury, which is why this method is considered a suitable initial response.
