Anti-Blaulicht-Sicherheitsbrille SA24189

Glasses that contain lenses specifically designed to reduce the amount of blue light that reaches the eye.
These lenses filter blue light rays to help prevent them from entering your eye and causing potential damage.
These glasses are made of special plastic that is very elastic, and it is almost impossible to break, so by bending the temple arm we can adjust them to our head so that they are as comfortable as possible.

The size of glasses is 50-17-138, 
Lens Width 50mm
Nasal Spacing 17mm
Temple Arm Length 138mm
Outer Frame Width 135mm

Measurements for Safe-Glasses can be found printed on the inside of the temple arm. Most eyewear brands print these details in a similar spot; if you already have a pair that you like, you can compare measurements to see how a certain frame of ours will fit you.

In that price you get

• Blue Light Blocking Rectangle Safe-Glasses,
• Leather glasses case,
• Cloth glasses bag,
• Microfiber cloth for cleaning, and
• Anti-blue light test kit to check is your glasses have blue light protection.
