Pilots wearing traditional sunglasses face potential permanent damage to their eyesight, Swiss exhibitor Caruso and Freeland warned at the show yesterday.

General manager Guiseppe Caruso said that blue light and infrared 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 (0.78oz), the glasses are very 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 pilot's headphones 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 ($265).
