Ultraviolet Light Fact Sheet

Overexposure to Ultraviolet (UV) light can cause:

  • Corneal burn
  • Gritty feeling in eye
  • Sunburn to face

Devices that emit UV light:

  • Transilluminator
  • Crosslinker
  • Biosafety cabinets (sterilization)

ANSI Z78.1 safety glasses or safety shields are rated shatterproof ONLY. They may NOT be UV proof.  UV-rated face shields are usually composed of special material that contains a UV coating, like a Lexan product, or have an orange tint.  Glass in hoods or biosafety cabinets may have a statement that it is UV proof. This may mean that the glass will not deteriorate under constant UV exposure, but may not protect you from UV burns.
