Introduction
Eye injuries caused by welding arc light: 1. The most serious ocular hazard of electric welding is photokeratitis, which causes conjunctival hyperemia, sharp pain, excessive tearing, and photophobia (inability to open the eyes); it can severely damage the cornea. 2. Repeated long-term exposure to electric welding light gradually leads to visual impairment. 3. Prolonged exposure to welding light impairs the elasticity of the eye’s crystalline lens, predisposing individuals to accommodative dysfunction.

Our eyes are extremely important to us; eye injuries can range from minor to severe. Some individuals, due to occupational exposure—such as welders—may sustain eye injuries. For instance, welding operations generate intense light that can harm the eyes. So, what specific ocular injuries can result from welding arc light? Let’s explore this together.

Ocular Injuries Caused by Welding Arc Light

1. The most serious ocular hazard associated with welding is photokeratitis (also known as “welder’s flash” or “arc eye”), which causes conjunctival injection (redness), sharp pain, excessive tearing, and photophobia (inability to open the eyes). It inflicts significant damage to the cornea.

2. Repeated, long-term exposure to welding light gradually leads to progressive visual impairment and decreased visual acuity.

3. Prolonged exposure to welding light impairs the elasticity of the eye’s crystalline lens, predisposing individuals to accommodative dysfunction.

4. Chronic ultraviolet (UV) radiation emitted during welding can induce lens opacification, ultimately leading to cataract formation.

5. Exposure to welding light increases susceptibility to conjunctivitis and dry eye syndrome.

6. UV radiation from welding causes photochemical damage to ocular tissues, resulting in protein denaturation and coagulation, as well as necrosis and desquamation of the corneal epithelium.

The above outlines the potential ocular injuries caused by welding arc light. Therefore, welders must always implement appropriate protective measures when performing welding tasks—specifically, wearing certified protective face shields or safety goggles to prevent eye injury. Should an injury occur, prompt medical evaluation at a hospital is strongly advised to assess the extent of ocular damage. Under physician guidance, topical antibiotic eye drops may be prescribed to prevent infection, and growth factor–containing eye drops may support corneal healing. We hope this information proves helpful to you.
