Flash burn (welder's keratitis)
This photo shows fluorescein uptake with diffuse punctate lesions of the cornea in a band-like distribution caused by exposure to ultraviolet radiation, in this case from an electric welding arc. Sunlight can also cause such an injury. In this characteristic exposure pattern, the eyelids spare the superior and inferior cornea, which distinguishes this injury from a diffuse infectious process (eg, adenovirus).
