Why use safety glasses?

Laser radiation can cause permanent damage to your eyes even after short-term exposure. These high optical density (OD) glasses effectively block dangerous wavelengths and protect your eyes from both direct and reflected radiation. The clear lenses ensure comfort and good vision even during extended work.

What should you watch out for?

Always check before use that the wavelength of your laser falls within the protective range of these glasses. When working with powerful lasers, we recommend combining it with other safety measures.
