Can blurred vision after arc-eye (welder’s flash) heal spontaneously?

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, the intense light generated during welding can damage the eyes. So, can blurred vision following “welder’s flash” (photokeratitis) resolve spontaneously? Let’s explore this further.

Can blurred vision after welder’s flash resolve spontaneously?

Blurred vision resulting from welder’s flash typically resolves within approximately 24 hours, provided no complications develop. Visual acuity usually returns to normal during this period. Treatment may include levofloxacin eye drops (administered six times daily) and sodium hyaluronate eye drops (also six times daily), with a 10-minute interval between the two medications. Additionally, warm compresses applied to closed eyes while resting can accelerate recovery.

Blurred vision following welding is medically termed “arc eye” or “photokeratitis.” Patients often experience sudden, severe ocular pain that awakens them in the middle of the night—typically hours after welding exposure during the day. In addition to eye pain, excessive tearing, and photophobia (inability to open the eyes), patients commonly report significant visual blurring. This condition arises from overexposure of the cornea and conjunctiva to ultraviolet (UV) radiation emitted during welding. The UV exposure causes superficial damage to the corneal epithelium, leading to punctate epithelial erosions. These erosions expose underlying corneal nerve endings, triggering intense pain, lacrimation, and blepharospasm (involuntary eyelid closure). During this time, it is crucial to rest the eyes and avoid rubbing them.

The above addresses whether blurred vision after welder’s flash can resolve spontaneously. If symptoms are mild, topical eye drops and adequate rest may suffice for full recovery. However, if symptoms are severe—or worsen—prompt medical evaluation at a hospital is strongly recommended to prevent complications and ensure timely management.
