Laser Eyewear Frequently Asked Questions


What is the lead time for my order?

Most orders for Polymer products are shipped within 72 hours after receipt. If an item is not in stock, you will receive an order acknowledgement with the expected ship date. The lead time for custom orders will be quoted on an individual basis.

What is the warranty on laser eyewear?

All products are warrantied to be free from defects in materials and/or workmanship for one year from date of purchase. If a frame breaks or malfunctions, it will be replaced at no charge for a period of 5 years.

What is optical density or O.D.?"

Optical density, or O.D. as is 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.

What about femtosecond eyewear?"

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 by email, or by calling (800) 94-LASER, to be sure the eyewear you choose is correct.
