The original aviators featured gold frames and green lenses for a reason. Green lenses block out blue light, which is incredibly important for a pilot flying above the clouds. Green lenses also help reduce glare. This color lens is so ubiquitous with aviators that it's been given its own name — G15 because they only let 15% of light in. The Ray Ban Aviator Classic Sunglasses still come in this original colorway. So if you're looking for the most classic aviator style, go for the green lenses and gold frames.
