Ask the MB: John Lennon's Clip-On Sunglasses
--Scott
A: We've asked our glasses expert for further clarification. "Even people in the industry don't use the terms 'P3' or 'P4' correctly, or at all," he says. "Find 3 people who use the words, and you'll get 3 different explanations, ranging from 'It's a military code word for the frame style,' to 'It's the relationship between the a and b dimensions.'
"Our understanding is that P3 refers to '3 points' -- the P3 shape is like a rounded, upside down triangle ... it has 3 points. Similarly, a P4 has 4 points and is usually a trapezoidal shape. If you look carefully at the photo of Lennon with sunglass clips, you can make out that he has P3 frames underneath and a P4 sunglass clip over them."
To attain the same effect, we recommend you purchase these vintage Polaroid aviator clip-ons. That way, your brain can imagine the world living as one all it wants, but your face will be packing the fire-power of two branches of our Armed Forces.
MB Recommends: If you don't already own a pair of P3s, we like Randolph Engineering's brand-new 49mm take on them.
