PROTOS

Protos glasses are suitable for all heads as the temples vary in length and angles. The nose bridges also adapt to the width of the nose. This ensures good ventilation of the glasses.

Maximum mechanical resistance to extreme temperatures in compliance with EN 166:2002 is no problem for the Protos. This applies to both the lenses and the temples, making them extremely robust but still very light. In addition to stability, the glasses are equipped with a UV filter in compliance with EN 172:2002. This means that the invisible risks of sunlight cannot cause any damage to the eyes.

The glasses are connected directly to the inner shell and do not interfere with comfort and sound insulation when using hearing protection.
