Comments

Causes of occupational cataracts include microwaves, TNT, ionizing radiation, infrared radiation, naphthalene, dinitrophenol, dinitro-o-cresol, and ethylene oxide. [Mullan] Intense exposure to UV light in the 295-320 nm range can cause cataracts that usually appear within 24 hours. Cataracts caused by chronic exposure to UV light of wavelength greater than 320 nm have been reported. [LaDou, p. 185] "X-ray radiation in a dose of 500-800 R directed toward the lens surface can cause cataracts, sometimes with a delay of several months to a year before the opacities appear." [LaDou, p. 148]
