For a long time considered as a simple accessory, sunglasses are the best ally to filter UVA and UVB ligh that is harmful for the eye health.

 

Despite the use of traditional sun lenses, an uncomfortable glare can however be felt under certain conditions of use. The reverberation of the sunrays by reflective surfaces creates a discomfort that is mainly felt under certain driving conditions or during nautical and mountain activities.

 

Polarised lenses include a plastic film of polyvinyl alcohol invisible to a bare eye. Once stretched, the long molecules, act like horizontally aligned wires that prevent the reflected light from going through.

 

Sun lenses with built-in film, only let through the light that contain the information. In addition to UV protection, polarised lenses improve contrast and enhance colours to ensure maximum viewing comfort.
