SUNGLASSES FOR PILOTS are designed to protect the eyes from the intense glare and UV rays encountered during flight while also enhancing visual clarity and reducing fatigue. Polarized and aviation-specific sunglasses are commonly used by pilots, with each offering distinct advantages.
1. Polarized Sunglasses for Pilots:
Function:
- Polarization reduces glare from reflective surfaces like the windshield, water, or snow, improving clarity and reducing eye strain.
- UV Protection: Most polarized sunglasses provide 100% UV protection, which is crucial to protect the eyes from harmful UV radiation, especially at high altitudes.
Benefits:
- Glare Reduction: Polarized lenses block horizontal light waves, which are the primary cause of glare. This allows for clearer visibility of instruments and the horizon.
- Enhanced Contrast and Clarity: Polarized lenses enhance contrast, making it easier to distinguish between different elements of the sky, clouds, and landscape.
- Comfort: Reducing glare can help alleviate eye fatigue, which is important during long flights.
- Safety: By minimizing glare, polarized sunglasses reduce the risk of misjudging distances or terrain visibility, especially during landing approaches.
Considerations:
- Instrument Visibility: Some polarized sunglasses can make it harder to see certain digital displays, particularly those with LCD screens in the cockpit. Pilots must be aware of this and test their sunglasses with their equipment.
- Water Reflection: Polarized lenses are especially effective for pilots flying over water, as they eliminate reflections from the water’s surface, improving visibility.
2. Aviation-Specific Sunglasses:
Aviation-specific sunglasses are designed to meet the unique needs of pilots, combining comfort, durability, and visual clarity while flying.
Features of Aviation-Specific Sunglasses:
- Lens Color and Tints:
- Gray/Neutral: The most common color for aviation sunglasses, providing true color perception and reducing overall brightness without distorting colors.
- Yellow or Amber: These lenses improve contrast and depth perception in low-light conditions, such as during early morning or evening flights. They also enhance visibility when flying in haze or fog.
- Blue or Green: Lenses with a blue or green tint can reduce glare and enhance contrast, though they may not be as versatile as gray or amber for pilots.
- Anti-Reflective Coating: Some aviation sunglasses feature anti-reflective coatings to reduce glare from light reflecting off the inside of the lenses.
- Wraparound Frames: The wraparound style helps eliminate side glare and offers better protection from wind, dust, and debris. This is particularly important during open-cockpit flying or when exposed to high winds.
- Lightweight Frames: Pilots often wear sunglasses for extended periods, so lightweight frames are a common feature. Materials like titanium or durable plastic are often used.
- Comfort: Adjustable nose pads and temples ensure a secure fit, preventing the glasses from slipping during maneuvers. A comfortable, well-fitting pair of sunglasses is crucial to avoid distractions during flight.
- Durability: Aviation sunglasses are designed to withstand the stresses of flying, including pressure changes and exposure to extreme temperatures, ensuring they last longer under demanding conditions.
Popular Brands and Models for Pilots:
- Ray-Ban Aviator: One of the most iconic sunglasses, Ray-Ban’s aviator design is both stylish and functional. Their polarized models offer excellent glare reduction, and their classic metal frame is lightweight and durable.
- Bolle Safety Aviation Glasses: Known for offering high-quality, lightweight sunglasses specifically tailored for aviation use, Bolle’s polarized lenses reduce glare and enhance visual acuity.
- Wiley X Pilot Sunglasses: Designed for military pilots, these sunglasses are built to meet aviation standards, providing impact resistance, UV protection, and high-contrast lenses for enhanced visibility.
- Cebe Veloce: A French brand offering aviation-specific sunglasses with polarized lenses, designed to withstand the rigors of flying while providing clear vision and comfort.
- Serengeti Aviation Sunglasses: Known for their photochromic lenses, Serengeti sunglasses automatically adjust to changing light conditions, ensuring pilots maintain clear vision at all times.
Conclusion:
For pilots, polarized sunglasses are essential for reducing glare, improving clarity, and enhancing comfort during flights, especially in bright conditions. Aviation-specific sunglasses offer specialized features such as anti-reflective coatings, enhanced contrast, and durable frames to meet the unique demands of flight. Whether flying in bright daylight or low-light conditions, the right pair of sunglasses will help protect the eyes, reduce fatigue, and improve safety by maintaining clear visibility of instruments, terrain, and the horizon.
