Why do you need laser goggles?

Even with diffused radiation, certain lasers are capable of inflicting lasting eye damage or blindness!

When there's any chance that you could be exposed to laser radiation of any type, you should wear laser safety glasses.

Laser glasses should be worn at all times in the area of a laser.

What are the important specifications of safety goggles?

The wavelength of the laser

It is measured in nanometers, and can help you select the proper lens to protect your eyes from the wavelength of your laser.

• Wavelength of xTool Machines are listed below:
•   M1 455nm
•   D1 450-460 nm
•   D1 Pro 450-460 nm

Optical density/ OD

Optical density quantifies how much light transmitted from a specific wavelength is blocked (also referred to as attenuation) by the lens of laser safety glasses.

The higher the OD value, the better the attenuation and protection level.

Visible Light Transmission/ VLT% and Lens Color

The amount of light that reaches your eyes through the lens is called visible light transmission (VLT). Lighter lens tints have a higher VLT because more light passes through the lens.

In general, with a larger percentage VLT, it is easier to see through the lens in low-light settings, and more color passes through the lens.

Comfortable fit over Rx glasses or alone

If they don't fit, the goggles may not be able to protect your eyes efficiently, and it's not comfortable wearing them.

Below are two examples of xTool safety goggles.
