Medical and fractional CO₂ lasers are the standard in surgery and aesthetic dermatology, where their energy is used for highly precise tissue ablation. Clinical staff are in close proximity to the beam and therefore require top-quality corneal protection which, however, must not distort skin colours in any way. EN 207 certification, combined with clear lenses, guarantees flawless clinical practice. During specific surface treatments or cleaning using CO₂ lasers, the operator is at risk of massive diffuse reflections in all directions. As the human cornea absorbs almost 100 per cent of the energy at a wavelength of 10,600 nm, comprehensive eye protection is an absolute necessity. Carefully selected filters combine guaranteed protection levels (LB) with a wide field of view and mechanical durability suitable for industrial environments.
