Who can I contact for technical questions?

A list of key technical and sales contacts can be found on our website or contact Glendale Customer Service at 1-800-500-4739.

How does laser safety eyewear work?

Glendale uses two types of lenses to properly attenuate laser exposures. Absorbtive technology literally absorbs the wavelength of the laser radiation while allowing the non-laser wavelengths to pass through the lenses. Glendale has two different absorptive technology platforms, dyes infused into polymeric filters or mineral glass (LGT®) and Dielectric (CLT®) technology, which reflects laser radiation. Warning: Laser eyewear is only design to provide protection against the wavelengths listed on the lens. Using the eyewear for any other wavelength can cause serious injury including blindness.

Can I have a scan of your filters?

Glendale can provide optical density scans of its eyewear. It is important to note that Glendale only guarantees the optical density / wavelength specifications that are labeled on the eyewear.

Do you have IPL eyewear that allows you to see better?

Yes, Glendale listened to customer demands for better visibility and developed Light SPEED™ eyewear. This fully patented eyewear uses Liquid Crystal technology that automatically reacts to an IPL pulse. Liquid Crystal Display optics darken during the IPL pulse and return to ambient viewing conditions after each pulse. Light SPEED eyewear has permanent UV and IR protection, as an added feature.

Where are your products manufactured?

All Glendale products are manufactured in our ISO certified, state-of-the-art facility in Smithfield, Rhode Island.

Can you develop a custom filter?

Yes, Glendale has an in-house laboratory, staffed by a Ph.D. Chemist and support staff. We have increased resources to synthesize dye for your application and will assist you in product development.

What do you recommend for patients in IPL, LED and laser procedures?

Glendale has developed a full line of reusable and disposable products for protecting patients in medical procedures such as Derm-Aid®, Laser-Aid® and IPL-Aid™. All of these products are CE marked to allow for worldwide usage. For a complete listing visit the patient care section of our website

How long have you been manufacturing laser safety eyewear?

Since 1968, when we supplied the US military with radiation filters.

Who develops your filter technology?

Our Ph.D. Chemist, with assistance from our sales, marketing and engineering staff.

Tell me about the experience level of your salespeople.

Glendale has the most experienced sales staff in the industry with over 90 years combined knowledge. Many of our staff are members of domestic and international laser safety standard organizations. They have published articles on laser safety, spoken at safety seminars at the big three automotive companies, DOE and DOD facilities. They have also attended basic and advanced laser safety officer training and some have obtained the elite status of a certified laser safety officer (CLSO).

Do you have a price list you can send me?

Yes, please contact our customer service department at 800-500-4739 and ask for a pdf version of our latest price list.

What does optical density or O.D. stand for?

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 1,000

You offer EN 207 and EN 208 certified laser eyewear. Which type do I need?

If you have a visible laser in the range of 400-700nm, and you have to be able to see the laser beam for your application, then you need EN 208 certified alignment eyewear.  In all other cases, you need laser safety eyewear certified to EN 207.

What is the difference between OD and EN 207 L-ratings?

EN 207 L-ratings take the length of time for which protection is guaranteed into account, namely 10 seconds for CW lasers or 100 pulses.  Further, EN 207 demands that both the frame and the lens meet the L-rating.
