Pilots wearing traditional sunglasses face potential permanent damage to their eyesight, Swiss exhibitor Caruso and Freeland has warned.

General manager Guiseppe Caruso warns that blue light and infra red light is not filtered by an aircraft windshield and can cause permanent damage to the retina.

The company had previously been developing anti-uv clothing and coatings and working with medical professionals it developed the Caruso P511 Pilot sunglasses. Weighing just 22g, the glasses are light and have side protection.

I am horrified when I see pilots without side protection - the damage can still be done," Caruso says. The company has integrated a blue light and infrared filter and includes an anti fog system. "We increased the contrast to the pilots more security, the clouds outline is sharper and you get much more depth. The thin arms will fit any pilots head phones or helmets."

Caruso and Freeland is also able to add reading glasses capability to the lenses or even make special adjustments for bi-focal or progressive lens. Prices start from €220 ($284.5).

Caruso also makes the point that you don't need to be a pilot to wear the glasses. "Technology has moved on a long way. The sun is dangerous for our sight whether we are flying or just on the ground. I encourage people to come by and try them - they will see the difference."
