For pilots, sunglasses are not a fashion accessory but a critical piece of safety equipment. Between intense glare at altitude, harmful UV exposure that increases with elevation, and the need to read cockpit instruments clearly, the demands placed on aviation eyewear go far beyond what everyday sunglasses are designed to handle. Whether you fly commercially, privately, or recreationally out of one of southern Alberta's many airfields, understanding what makes a great pair of pilot sunglasses is essential.
Why Pilots Face Elevated UV Risk
UV radiation intensity increases approximately 4 to 5 percent for every 1,000 feet of altitude gained. A pilot flying at 10,000 feet is exposed to roughly 40 to 50 percent more UV than someone on the ground. At cruising altitudes of 30,000 feet or higher, the atmosphere provides significantly less filtration, and cockpit windshields, while blocking most UVB, transmit a substantial amount of UVA radiation.
This cumulative exposure over a career contributes to an elevated risk of cataracts, macular degeneration, and other UV-related eye conditions. Pilots who also have a genetic predisposition to these conditions face compounded risk, making proper eye protection even more important.
The Polarization Problem in Aviation
Polarized lenses are celebrated in most outdoor contexts for their ability to cut reflected glare. However, aviation is one of the few environments where polarization can actually create safety hazards. Here is why:
LCD Instrument Interference
Modern glass cockpits use LCD screens for primary flight displays, navigation, and engine monitoring. LCD screens emit polarized light, and when viewed through polarized sunglasses at certain angles, the display can appear to dim, distort, or completely black out. In a critical phase of flight, losing visibility of your instruments even momentarily is unacceptable.
Windscreen Stress Patterns
Aircraft windshields are made from laminated or tempered materials that contain internal stress patterns. Polarized lenses can make these patterns visible as rainbow-coloured bands or patches, which are distracting and can obscure your view of the sky ahead.
Reduced Visibility of Other Aircraft
Polarized lenses can sometimes filter out the glint of sunlight reflecting off another aircraft, which is one of the primary visual cues pilots use to spot traffic. Reducing this glint can delay traffic acquisition, a genuine safety concern in busy airspace.
Transport Canada and the FAA both advise against polarized lenses for pilots. Non-polarized lenses with good UV protection and appropriate tint are the recommended alternative.
Best Lens Tints for the Cockpit
The ideal aviation lens reduces overall brightness without distorting colours, since colour recognition is critical for reading instruments, identifying terrain, and spotting other aircraft. The following tints are widely considered the best options:
- Grey / Neutral Density: The most popular choice among pilots. Grey lenses reduce brightness evenly across the colour spectrum, preserving true colour perception. They work well in bright conditions without altering the appearance of instrument displays or navigation lights.
- Green (G-15): The classic Ray-Ban aviator tint. Green lenses offer excellent contrast and true colour rendering in bright conditions. They provide a slight boost to green and blue tones, which can be helpful for distinguishing terrain features.
- Brown / Amber: Good for enhancing contrast in hazy conditions, which can aid in spotting traffic against a washed-out sky. However, they shift colour perception slightly, so pilots need to ensure they can still accurately identify the colours of navigation lights and instrument warnings.
Gradient tints, which are darker at the top and lighter at the bottom, are another practical option for pilots. They reduce overhead glare from the sun while allowing a lighter view of the instrument panel below.
Frame Design for Aviation
The iconic teardrop-shaped aviator frame was literally designed for pilots, and its design principles remain relevant:
- Large lens coverage: The teardrop shape provides wide vertical and horizontal coverage, protecting against light entering from above and the sides. This is important when the sun is high or when banking the aircraft.
- Thin metal temples: Wire or bayonet-style temples (straight arms rather than curved hooks) fit comfortably under aviation headsets without creating pressure points during long flights.
- Lightweight construction: Titanium and thin metal alloy frames minimize weight and reduce fatigue during multi-hour flights.
- Adjustable nose pads: These allow precise positioning so the lenses sit in the optimal position relative to your eyes, which is especially important if you need to look over the top of the lenses to read close-up instruments.
Prescription Considerations for Pilots
Many pilots require corrective lenses, and Canadian aviation medical standards specify minimum visual acuity requirements. If you need a prescription, aviation sunglasses can be fitted with single-vision or progressive lenses. Progressives are particularly useful for pilots over 40 who need to alternate between scanning the sky, reading instruments at arm's length, and reviewing charts or approach plates up close.
When choosing progressive lenses for aviation, ensure the fitting is optimized so the intermediate zone aligns with your natural instrument-scanning gaze. An experienced optician can adjust the fitting height to account for the specific cockpit geometry you fly in most often.
Recommended Brands for Pilots
Ray-Ban Aviator
The original aviation sunglass, designed in 1936 for US Army Air Corps pilots. The classic RB3025 with G-15 green lenses remains one of the best non-polarized options for the cockpit. The teardrop shape, lightweight metal frame, and optical-quality glass lenses have stood the test of time.
Maui Jim
While Maui Jim is best known for polarized lenses, they also offer non-polarized options with their SuperThin Glass technology, providing excellent clarity and UV protection without the LCD interference concerns. Their lens quality is among the best available.
Oakley
Oakley's High Definition Optics meet ANSI Z87.1 impact standards, and their non-polarized Prizm lenses offer enhanced contrast in specific environments. Their more modern frame designs appeal to pilots who prefer a contemporary look over the classic aviator style.
Caring for Aviation Sunglasses
Flight bags, cockpit sun, and the general wear of aviation life can take a toll on your sunglasses. Store them in a hard case with a microfibre pouch when not in use. Avoid leaving them on the glareshield, where direct sun and heat can damage lens coatings and warp frames. Clean lenses with a proper lens cleaner and microfibre cloth; abrasive materials or dry wiping can scratch coatings and compromise optical quality over time.
