Pilots require eye protection that goes above and beyond the standard protection against ultraviolet (UV) radiation. It is only with the use of additional filters that pilots’ eyes can be adequately protected against cataracts, age-related macular degeneration and retinal detachment, further details of which can be found in a press release issued by the Schaffhausen-based glasses manufacturer CARUSO & FREELAND.
For this reason, the company uses both UV and blue light for its modular aviation sunglasses, with infrared filters an optional extra. These also offer properties including contrast enhancement and additional side protection. Moreover, prescription glasses are compatible with the company’s sunglasses.
However, the use of polarization filters is not permitted in the aviation industry. This is due to the fact that polarizing filters in sunglasses and those already built into the displays can obscure the view of cockpit displays depending on the angle of sight. In turn, this would significantly endanger safety.
A two-year scientific study has now proven that CARUSO aviation sunglasses offer the necessary increased level of eye protection. The study, which was published in the journal “Health and Physics”, was carried out in conjunction with the University of Applied Sciences and Arts Northwestern Switzerland (FHNW) in compliance with the global guidelines of the International Commission on Non-Ionizing Radiation Protection. It ultimately found that pilots must be protected more rigorously than is usually the case at present.
