All products are warrantied to be free from defects in materials and/or workmanship for one year from the date of purchase. Frames are warranted against defects in material and workmanship for a period of 5 years.
Optical density, or O.D. as it is commonly known, refers to the attenuation factor of the filter to the base 10. Therefore, a filter with an OD of 2 attenuates the laser by a factor of 10 to the 2nd or 100, an OD of 3 attenuates the laser beam by a factor of 1,000, an OD of 4 by a factor of 10,000.
Some filters may exhibit saturated absorption when exposed to femtosecond laser pulses and may not afford adequate laser eyewear protection for those laser types. Please contact an RLI representative to be sure the eyewear you choose is correct.
Visible Light Transmittance (VLT) is the amount of visible light passing through a filter, weighted for a response of the human eye, expressed as a percentage.
RLI recommends using mild detergent /soap and warm water, or our Optical cleaning kit to keep eyewear clean and in proper working order. Harsh chemicals such as acidic cleaners may harm the lens or frame over time. Do not use ultrasonic waves.
RLI eyewear meets all ANSI Z87.1 impact standards.
