Non-Polarized Vs. Polarized
Pilots typically wear non-polarized sunglasses to ensure they can clearly see their cockpit instruments, which often have their own anti-glare filters. Polarized sunglasses, while reducing glare from ambient light, can interfere with the visibility of these displays.
- Non-polarized lenses protect eyes from sunlight without filtering glare.
- Polarized filters block horizontal light waves, enhancing contrast but may distort instrument readings.
- Gray lenses are recommended due to minimal color distortion.
Eye Protection and Sunglass Features
The demand for effective eye protection for pilots is crucial due to the high UV radiation exposure at altitude. Non-polarized sunglasses that offer protection from UVA and UVB rays are vital for maintaining good eyesight during flights.
- Polycarbonate lenses are popular for their lightweight and impact resistance.
- Different tints like green or dark red can improve visual sharpness or assist with night vision.
- Sunglasses must not obstruct the pilot’s ability to see instruments or during taxiing, takeoff, and landing.
Sunglass Regulations and Preferences
While not legally required, pilots often wear sunglasses to reduce eye fatigue and protect against solar radiation and potential impacts.
- Cockpit displays and instruments necessitate non-polarized sunglasses to avoid vision distortion.
- Prescription sunglasses are permissible, with considerations for clear lenses for night flying.
- Non-polarized aviator sunglasses with gray lenses are preferred for their fit and effectiveness.
- Sunglasses must accommodate other headwear and oxygen masks for pilots when necessary.
