The pilot wearing sunglasses is an iconic image of the United States, often appearing in movies, magazines, history books, etc. These classic images attract our common appreciation for freedom, courage, innovation and exploration.
Yes, if you are a pilot, you can wear glasses. This is true for both commercial and military pilots. For commercial airlines, all pilots who have refractive errors and affect long-range vision are required to wear prescription glasses or contact lenses to correct their vision to 20/20. Commercial pilots with refractive errors and presbyopia should wear progressive lenses or other multifocal glasses to ensure a clear field of vision at all distances.
It is recommended that all pilots who need prescription glasses or contact lenses to achieve 20/20 vision always carry extra glasses or contact lenses as a backup when flying.
A perfect vision without glasses is not a requirement for military pilots. The vision requirements of military personnel are unique to each department of the military.
The US Air Force has the following visual requirements for its service personnel: The physical examination before admission must fully assess the field of vision of the conscription. The refractive error of all service members cannot exceed +8.00 diopters (D) to -8.00D. The pilot's uncorrected long-distance vision must be no less than 20/70 per eye, and the vision of each eye must be correctable to 20/20 or better. Without corrective lenses, the pilot's myopia must be 20/20 or higher The pilot must have normal color vision.
For pilots, sunglasses are one of the most important assets for protecting pilots. Pilots are more likely to be exposed to strong sunlight and solar radiation than any other occupation, which can fatigue eyes, cause long-term damage to tissues, and even cause cataracts. According to data from the Federal Aviation Administration, for every additional 1,000 feet of altitude, ultraviolet radiation increases by about 5%.
The choice of polit sunglasses depends on your preferences. There are anti-reflective sunglasses, mirrored lens sunglasses, ce uv400 sunglasses, etc.
For frames, it is only recommended that you look for sturdy sunglasses. Regarding lenses, we recommend:
1. Wear sunglasses with 100% UV protection.
2. Look for sunglasses with large lenses.
3. The lens should be dyed to optimize the visual effect, while minimizing color distortion. Look for neutral colors with light transmittance between 15% and 30%.
4. Avoid polarized lenses.
In the cockpit environment, sunglasses are important protective equipment. The following provides guidance for pilots to purchase sunglasses.
Hue should be neutral. In fact, gray or brown is acceptable. The chromaticity shall not be less than 80% of the absorption rate. Gradient colors (the darkest at the top of the lens and the brightest at the bottom of the lens) may be useful.
Photochromic lenses react with ultraviolet radiation by turning black. Because the cabin windshield is designed to block the transmission of ultraviolet light, these lenses will not work effectively in the cabin environment. Therefore it is not recommended to use these sunglasses.
Polarized lenses reduce the amount of light passing through the lens by selectively filtering certain electromagnetic spectral planes. These lenses may cause distorted patterns in some laminated cockpit windshields. They can also change the appearance of clouds and reduce ground reflections useful to VFR pilots. Therefore it is not recommended to use these sunglasses.
All frames should be properly installed and should be large enough to fully protect them from direct sunlight. All pilots who need prescription glasses must have a clear pair of corrective glasses, but the second pair can wear prescription sunglasses. Flat sunglasses cannot be worn on prescription glasses. For night flights, it is recommended not to color both prescription glasses.
We have a wide variety of sunglasses, suitable for both professional pilots and casual pilots. With built-in anti-ultraviolet function and glare reduction function, you can fly safely and observe the surrounding environment clearly and accurately.
