Great product and service... quick delivery

—— Fred Schmidt

This is the first company on all of this website that so far as I can tell does not lie about their products. Getting sick of companies claiming they have 10000, 30000 and even 50000 mw handheld lasers.

Frequently Asked Questions about Laser Safety Glasses


Rapid advances in laser technology have made laser safety more important than ever. New lasers in medicine, defense, research, and industry present unique challenges for safety and personal protection. Below is a list of frequently asked questions from customers, including how to clean laser goggles, how long laser goggles last, and why there are no laser goggles with full wavelength coverage.

Q: What is the lifespan of laser goggles?

A: The lifespan of laser goggles depends on how they are handled. The protective effect of absorbent filters does not diminish over time. Coated laser goggles will provide protection as long as the coating is not scratched. Careful cleaning, proper care, and environmental factors can all affect the lifespan of your glasses.

Do not use glasses with any defects (eg, damaged or scratched filters, color changes of filters, damaged metal fasteners in the frame). If you have any questions, please contact our technical support. Email:Tel:


Q: How do clean laser goggles?

A: Please clean the glasses with a mild neutral cleaner (eg mild household glass cleaner, mild soapy water), then dry gently with a soft cloth.

- Do not dry clean - may grind small particles

- do not immerse them in water

- Do not use chemicals or acidic cleaning fluids for cleaning

- Do not insert it into sanitizer or disinfectant

- Never use ultrasonic to clean them

- Factory-supplied microfiber bag for cleaning glasses

- According to safety guidelines, any repairs to this product should only be carried out by the manufacturer.


Q: Can I wear laser goggles to look directly into the laser beam?

A: Never look directly into the laser beam. Laser goggles are designed to protect against diffuse reflections and protect your eyes from accidental or direct exposure to the laser beam. How long a pair of laser goggles survives a direct hit will depend on the irradiance of the beam.


Q: Can glasses with the same parameters be matched with lenses of other colors?

A: No, even if the wavelength is the same, the color of the plastic filter and the glass filter will be different. The color of the lens depends on the dye or coating that protects the laser wavelengths.


Q: I have a pair of glasses (eg: YAG laser). Can I use them for my new laser too?

A: Laser goggles are marked with attenuation coefficient (optical density OD and EN standard grades) and design wavelength. To use with other lasers, first, calculate the optical density OD or EN standard rating. Damage from new lasers can be prevented if the attenuation coefficient and the wavelength of the markings match the markings on the glasses. Glasses should not be used with new lasers if the wavelength is outside the marked range or the attenuation coefficient is below the marked range.


Q: Why aren't there universal laser goggles that cover all wavelengths?

A: To cover all lasers, you need a material that does not transmit visibly, UV, and IR radiation (like steel, but does not transmit light). The wider the wavelength range required for protection, the more difficult it is. Certain wavelengths, such as UV from 190 nm to 360 nm, are readily available. But for visible infrared light, more wavelengths need to be covered. Assuming that all wavelengths need to be covered, the glasses will not be able to see through (equivalent to a piece of steel).
