Pilots, in particular, need to be concerned about the health of their eyes, and sunglasses maker Caruso & Freeland wants to help them to get the protection they need. Here at the MEBAA show, the Swiss company (Stand 915) is offering to test visitors’ sunglasses for free to evaluate how much protection they provide.

The Caruso & Freeland family of lightweight UV, blue light and infrared sunglasses for adults and children can increase 3D vision, reduce light stress and improve wide-angle view, claimed the company. They can also fit to a headset and helmet, which is ideal for pilots.

The company calls its sunglasses technology “Total Eye Protection.” This is because the sunglasses protect both the front (cornea and crystal lens) and rear (macular and retina) of the eyes from UV and infrared rays, as well as from blue light, which reaches the deepest parts of the eye. The sunglasses also feature filters for UV wavelengths of 400 nm, 450 nm and 460 nm.

Founded in 1996, Caruso & Freeland also makes other sun-protection products such as hats, shirts and shorts. According to a study conducted by the company, 15 percent of UVB rays and 42 percent of UVA rays penetrated a basic cotton shirt while zero percent of UVB rays and 3 percent of UVA rays penetrated its custom-made shirt.
