Arc eye, also known as arc flash, welder's flash, corneal flash burns, or flash burns, is a painful ocular condition sometimes experienced by welders who have failed to use adequate eye protection. It can also occur due to light from sunbeds, light reflected from snow (known as snow blindness), water or sand. The intense ultraviolet light emitted by the arc causes a superficial and painful keratitis.

Ultraviolet (UV) light is electromagnetic radiation with a wavelength shorter than that of visible light, but longer than soft X-rays. ...

Symptoms tend to occur a number of hours after exposure and typically resolve spontaneously within 36 hours. The sensation has been described as having sand poured into the eyes.

This phenomenon results from intense levels of illumination, greater than that of more common over-illumination found in many factories and offices. This cosmetics store has lighting levels over twice recommended levels and sufficient to trigger headaches and other health effects Over-illumination is the presence of lighting intensity (illuminance) beyond that required for a specified activity. ...

Standards

Four principal standards govern arc flash hazards :

• OSHA Standards 29-CFR, Part 1910. Occupational Safety and Health Standards. 1910 sub part S (electrical) Standard number 1910.333 specifically addresses Standards for Work Practices and references NFPA 70E.
• The National Fire Protection Association (NFPA) Standard 70 - 2002 “The National Electrical Code” (NEC) contains requirements for warning labels.
• NFPA 70E 2000 provides guidance on implementing appropriate work practices that are required to safeguard workers from injury while working on or near exposed electrical conductors or circuit parts that could become energized.
• The Institute of Electronics and Electrical Engineers (IEEE) 1584 – 2002 Guide to Performing Arc-Flash Hazard Calculations.

Arc flash hazard software exists that allow businesses to comply with the myriad of government regulations while proving their workforce with an optimally safe environment. Many software companies now offer arc flash hazard solutions. josh is wierd!

Signs

• Intense lacrimation
• Blepharospasm
• Photophobia [1]
• Fluorescein dye staining will reveal corneal ulcers under blue light

Management

• Instill topical anaesthesia
• Inspect the cornea for any foreign body
• Patch the worse of the two eyes and prescribe analgesia
• Topical antibiotics in the form of eye drops or eye ointment or both should be prescribed for prophylaxis against infection

Anesthesia (AE), also anaesthesia (BE), is the process of blocking the perception of pain and other sensations. ... The cornea is the transparent front part of the eye that covers the iris, pupil, and anterior chamber, providing most of an eyes optical power [1]. Together with the lens, the cornea refracts light and, as a result, helps the eye to focus. ...
