Photophthalmia, also known as ultraviolet eye inflammation, accounts for 2% of eye injuries. It is more common in metal welders or film workers under mercury lamps, as well as ultraviolet lamps, atomic bombs, etc., which may be caused by direct or indirect radiation. When the amount of exposure in one day accumulates to more than 15 minutes, symptoms can appear after 6 to 10 hours.
